Scientific Reports

What this handout is about.

This handout provides a general guide to writing reports about scientific research you’ve performed. In addition to describing the conventional rules about the format and content of a lab report, we’ll also attempt to convey why these rules exist, so you’ll get a clearer, more dependable idea of how to approach this writing situation. Readers of this handout may also find our handout on writing in the sciences useful.

Background and pre-writing

Why do we write research reports.

You did an experiment or study for your science class, and now you have to write it up for your teacher to review. You feel that you understood the background sufficiently, designed and completed the study effectively, obtained useful data, and can use those data to draw conclusions about a scientific process or principle. But how exactly do you write all that? What is your teacher expecting to see?

To take some of the guesswork out of answering these questions, try to think beyond the classroom setting. In fact, you and your teacher are both part of a scientific community, and the people who participate in this community tend to share the same values. As long as you understand and respect these values, your writing will likely meet the expectations of your audience—including your teacher.

So why are you writing this research report? The practical answer is “Because the teacher assigned it,” but that’s classroom thinking. Generally speaking, people investigating some scientific hypothesis have a responsibility to the rest of the scientific world to report their findings, particularly if these findings add to or contradict previous ideas. The people reading such reports have two primary goals:

  • They want to gather the information presented.
  • They want to know that the findings are legitimate.

Your job as a writer, then, is to fulfill these two goals.

How do I do that?

Good question. Here is the basic format scientists have designed for research reports:

  • Introduction

Methods and Materials

This format, sometimes called “IMRAD,” may take slightly different shapes depending on the discipline or audience; some ask you to include an abstract or separate section for the hypothesis, or call the Discussion section “Conclusions,” or change the order of the sections (some professional and academic journals require the Methods section to appear last). Overall, however, the IMRAD format was devised to represent a textual version of the scientific method.

The scientific method, you’ll probably recall, involves developing a hypothesis, testing it, and deciding whether your findings support the hypothesis. In essence, the format for a research report in the sciences mirrors the scientific method but fleshes out the process a little. Below, you’ll find a table that shows how each written section fits into the scientific method and what additional information it offers the reader.

Thinking of your research report as based on the scientific method, but elaborated in the ways described above, may help you to meet your audience’s expectations successfully. We’re going to proceed by explicitly connecting each section of the lab report to the scientific method, then explaining why and how you need to elaborate that section.

Although this handout takes each section in the order in which it should be presented in the final report, you may for practical reasons decide to compose sections in another order. For example, many writers find that composing their Methods and Results before the other sections helps to clarify their idea of the experiment or study as a whole. You might consider using each assignment to practice different approaches to drafting the report, to find the order that works best for you.

What should I do before drafting the lab report?

The best way to prepare to write the lab report is to make sure that you fully understand everything you need to about the experiment. Obviously, if you don’t quite know what went on during the lab, you’re going to find it difficult to explain the lab satisfactorily to someone else. To make sure you know enough to write the report, complete the following steps:

  • What are we going to do in this lab? (That is, what’s the procedure?)
  • Why are we going to do it that way?
  • What are we hoping to learn from this experiment?
  • Why would we benefit from this knowledge?
  • Consult your lab supervisor as you perform the lab. If you don’t know how to answer one of the questions above, for example, your lab supervisor will probably be able to explain it to you (or, at least, help you figure it out).
  • Plan the steps of the experiment carefully with your lab partners. The less you rush, the more likely it is that you’ll perform the experiment correctly and record your findings accurately. Also, take some time to think about the best way to organize the data before you have to start putting numbers down. If you can design a table to account for the data, that will tend to work much better than jotting results down hurriedly on a scrap piece of paper.
  • Record the data carefully so you get them right. You won’t be able to trust your conclusions if you have the wrong data, and your readers will know you messed up if the other three people in your group have “97 degrees” and you have “87.”
  • Consult with your lab partners about everything you do. Lab groups often make one of two mistakes: two people do all the work while two have a nice chat, or everybody works together until the group finishes gathering the raw data, then scrams outta there. Collaborate with your partners, even when the experiment is “over.” What trends did you observe? Was the hypothesis supported? Did you all get the same results? What kind of figure should you use to represent your findings? The whole group can work together to answer these questions.
  • Consider your audience. You may believe that audience is a non-issue: it’s your lab TA, right? Well, yes—but again, think beyond the classroom. If you write with only your lab instructor in mind, you may omit material that is crucial to a complete understanding of your experiment, because you assume the instructor knows all that stuff already. As a result, you may receive a lower grade, since your TA won’t be sure that you understand all the principles at work. Try to write towards a student in the same course but a different lab section. That student will have a fair degree of scientific expertise but won’t know much about your experiment particularly. Alternatively, you could envision yourself five years from now, after the reading and lectures for this course have faded a bit. What would you remember, and what would you need explained more clearly (as a refresher)?

Once you’ve completed these steps as you perform the experiment, you’ll be in a good position to draft an effective lab report.

Introductions

How do i write a strong introduction.

For the purposes of this handout, we’ll consider the Introduction to contain four basic elements: the purpose, the scientific literature relevant to the subject, the hypothesis, and the reasons you believed your hypothesis viable. Let’s start by going through each element of the Introduction to clarify what it covers and why it’s important. Then we can formulate a logical organizational strategy for the section.

The inclusion of the purpose (sometimes called the objective) of the experiment often confuses writers. The biggest misconception is that the purpose is the same as the hypothesis. Not quite. We’ll get to hypotheses in a minute, but basically they provide some indication of what you expect the experiment to show. The purpose is broader, and deals more with what you expect to gain through the experiment. In a professional setting, the hypothesis might have something to do with how cells react to a certain kind of genetic manipulation, but the purpose of the experiment is to learn more about potential cancer treatments. Undergraduate reports don’t often have this wide-ranging a goal, but you should still try to maintain the distinction between your hypothesis and your purpose. In a solubility experiment, for example, your hypothesis might talk about the relationship between temperature and the rate of solubility, but the purpose is probably to learn more about some specific scientific principle underlying the process of solubility.

For starters, most people say that you should write out your working hypothesis before you perform the experiment or study. Many beginning science students neglect to do so and find themselves struggling to remember precisely which variables were involved in the process or in what way the researchers felt that they were related. Write your hypothesis down as you develop it—you’ll be glad you did.

As for the form a hypothesis should take, it’s best not to be too fancy or complicated; an inventive style isn’t nearly so important as clarity here. There’s nothing wrong with beginning your hypothesis with the phrase, “It was hypothesized that . . .” Be as specific as you can about the relationship between the different objects of your study. In other words, explain that when term A changes, term B changes in this particular way. Readers of scientific writing are rarely content with the idea that a relationship between two terms exists—they want to know what that relationship entails.

Not a hypothesis:

“It was hypothesized that there is a significant relationship between the temperature of a solvent and the rate at which a solute dissolves.”

Hypothesis:

“It was hypothesized that as the temperature of a solvent increases, the rate at which a solute will dissolve in that solvent increases.”

Put more technically, most hypotheses contain both an independent and a dependent variable. The independent variable is what you manipulate to test the reaction; the dependent variable is what changes as a result of your manipulation. In the example above, the independent variable is the temperature of the solvent, and the dependent variable is the rate of solubility. Be sure that your hypothesis includes both variables.

Justify your hypothesis

You need to do more than tell your readers what your hypothesis is; you also need to assure them that this hypothesis was reasonable, given the circumstances. In other words, use the Introduction to explain that you didn’t just pluck your hypothesis out of thin air. (If you did pluck it out of thin air, your problems with your report will probably extend beyond using the appropriate format.) If you posit that a particular relationship exists between the independent and the dependent variable, what led you to believe your “guess” might be supported by evidence?

Scientists often refer to this type of justification as “motivating” the hypothesis, in the sense that something propelled them to make that prediction. Often, motivation includes what we already know—or rather, what scientists generally accept as true (see “Background/previous research” below). But you can also motivate your hypothesis by relying on logic or on your own observations. If you’re trying to decide which solutes will dissolve more rapidly in a solvent at increased temperatures, you might remember that some solids are meant to dissolve in hot water (e.g., bouillon cubes) and some are used for a function precisely because they withstand higher temperatures (they make saucepans out of something). Or you can think about whether you’ve noticed sugar dissolving more rapidly in your glass of iced tea or in your cup of coffee. Even such basic, outside-the-lab observations can help you justify your hypothesis as reasonable.

Background/previous research

This part of the Introduction demonstrates to the reader your awareness of how you’re building on other scientists’ work. If you think of the scientific community as engaging in a series of conversations about various topics, then you’ll recognize that the relevant background material will alert the reader to which conversation you want to enter.

Generally speaking, authors writing journal articles use the background for slightly different purposes than do students completing assignments. Because readers of academic journals tend to be professionals in the field, authors explain the background in order to permit readers to evaluate the study’s pertinence for their own work. You, on the other hand, write toward a much narrower audience—your peers in the course or your lab instructor—and so you must demonstrate that you understand the context for the (presumably assigned) experiment or study you’ve completed. For example, if your professor has been talking about polarity during lectures, and you’re doing a solubility experiment, you might try to connect the polarity of a solid to its relative solubility in certain solvents. In any event, both professional researchers and undergraduates need to connect the background material overtly to their own work.

Organization of this section

Most of the time, writers begin by stating the purpose or objectives of their own work, which establishes for the reader’s benefit the “nature and scope of the problem investigated” (Day 1994). Once you have expressed your purpose, you should then find it easier to move from the general purpose, to relevant material on the subject, to your hypothesis. In abbreviated form, an Introduction section might look like this:

“The purpose of the experiment was to test conventional ideas about solubility in the laboratory [purpose] . . . According to Whitecoat and Labrat (1999), at higher temperatures the molecules of solvents move more quickly . . . We know from the class lecture that molecules moving at higher rates of speed collide with one another more often and thus break down more easily [background material/motivation] . . . Thus, it was hypothesized that as the temperature of a solvent increases, the rate at which a solute will dissolve in that solvent increases [hypothesis].”

Again—these are guidelines, not commandments. Some writers and readers prefer different structures for the Introduction. The one above merely illustrates a common approach to organizing material.

How do I write a strong Materials and Methods section?

As with any piece of writing, your Methods section will succeed only if it fulfills its readers’ expectations, so you need to be clear in your own mind about the purpose of this section. Let’s review the purpose as we described it above: in this section, you want to describe in detail how you tested the hypothesis you developed and also to clarify the rationale for your procedure. In science, it’s not sufficient merely to design and carry out an experiment. Ultimately, others must be able to verify your findings, so your experiment must be reproducible, to the extent that other researchers can follow the same procedure and obtain the same (or similar) results.

Here’s a real-world example of the importance of reproducibility. In 1989, physicists Stanley Pons and Martin Fleischman announced that they had discovered “cold fusion,” a way of producing excess heat and power without the nuclear radiation that accompanies “hot fusion.” Such a discovery could have great ramifications for the industrial production of energy, so these findings created a great deal of interest. When other scientists tried to duplicate the experiment, however, they didn’t achieve the same results, and as a result many wrote off the conclusions as unjustified (or worse, a hoax). To this day, the viability of cold fusion is debated within the scientific community, even though an increasing number of researchers believe it possible. So when you write your Methods section, keep in mind that you need to describe your experiment well enough to allow others to replicate it exactly.

With these goals in mind, let’s consider how to write an effective Methods section in terms of content, structure, and style.

Sometimes the hardest thing about writing this section isn’t what you should talk about, but what you shouldn’t talk about. Writers often want to include the results of their experiment, because they measured and recorded the results during the course of the experiment. But such data should be reserved for the Results section. In the Methods section, you can write that you recorded the results, or how you recorded the results (e.g., in a table), but you shouldn’t write what the results were—not yet. Here, you’re merely stating exactly how you went about testing your hypothesis. As you draft your Methods section, ask yourself the following questions:

  • How much detail? Be precise in providing details, but stay relevant. Ask yourself, “Would it make any difference if this piece were a different size or made from a different material?” If not, you probably don’t need to get too specific. If so, you should give as many details as necessary to prevent this experiment from going awry if someone else tries to carry it out. Probably the most crucial detail is measurement; you should always quantify anything you can, such as time elapsed, temperature, mass, volume, etc.
  • Rationale: Be sure that as you’re relating your actions during the experiment, you explain your rationale for the protocol you developed. If you capped a test tube immediately after adding a solute to a solvent, why did you do that? (That’s really two questions: why did you cap it, and why did you cap it immediately?) In a professional setting, writers provide their rationale as a way to explain their thinking to potential critics. On one hand, of course, that’s your motivation for talking about protocol, too. On the other hand, since in practical terms you’re also writing to your teacher (who’s seeking to evaluate how well you comprehend the principles of the experiment), explaining the rationale indicates that you understand the reasons for conducting the experiment in that way, and that you’re not just following orders. Critical thinking is crucial—robots don’t make good scientists.
  • Control: Most experiments will include a control, which is a means of comparing experimental results. (Sometimes you’ll need to have more than one control, depending on the number of hypotheses you want to test.) The control is exactly the same as the other items you’re testing, except that you don’t manipulate the independent variable-the condition you’re altering to check the effect on the dependent variable. For example, if you’re testing solubility rates at increased temperatures, your control would be a solution that you didn’t heat at all; that way, you’ll see how quickly the solute dissolves “naturally” (i.e., without manipulation), and you’ll have a point of reference against which to compare the solutions you did heat.

Describe the control in the Methods section. Two things are especially important in writing about the control: identify the control as a control, and explain what you’re controlling for. Here is an example:

“As a control for the temperature change, we placed the same amount of solute in the same amount of solvent, and let the solution stand for five minutes without heating it.”

Structure and style

Organization is especially important in the Methods section of a lab report because readers must understand your experimental procedure completely. Many writers are surprised by the difficulty of conveying what they did during the experiment, since after all they’re only reporting an event, but it’s often tricky to present this information in a coherent way. There’s a fairly standard structure you can use to guide you, and following the conventions for style can help clarify your points.

  • Subsections: Occasionally, researchers use subsections to report their procedure when the following circumstances apply: 1) if they’ve used a great many materials; 2) if the procedure is unusually complicated; 3) if they’ve developed a procedure that won’t be familiar to many of their readers. Because these conditions rarely apply to the experiments you’ll perform in class, most undergraduate lab reports won’t require you to use subsections. In fact, many guides to writing lab reports suggest that you try to limit your Methods section to a single paragraph.
  • Narrative structure: Think of this section as telling a story about a group of people and the experiment they performed. Describe what you did in the order in which you did it. You may have heard the old joke centered on the line, “Disconnect the red wire, but only after disconnecting the green wire,” where the person reading the directions blows everything to kingdom come because the directions weren’t in order. We’re used to reading about events chronologically, and so your readers will generally understand what you did if you present that information in the same way. Also, since the Methods section does generally appear as a narrative (story), you want to avoid the “recipe” approach: “First, take a clean, dry 100 ml test tube from the rack. Next, add 50 ml of distilled water.” You should be reporting what did happen, not telling the reader how to perform the experiment: “50 ml of distilled water was poured into a clean, dry 100 ml test tube.” Hint: most of the time, the recipe approach comes from copying down the steps of the procedure from your lab manual, so you may want to draft the Methods section initially without consulting your manual. Later, of course, you can go back and fill in any part of the procedure you inadvertently overlooked.
  • Past tense: Remember that you’re describing what happened, so you should use past tense to refer to everything you did during the experiment. Writers are often tempted to use the imperative (“Add 5 g of the solid to the solution”) because that’s how their lab manuals are worded; less frequently, they use present tense (“5 g of the solid are added to the solution”). Instead, remember that you’re talking about an event which happened at a particular time in the past, and which has already ended by the time you start writing, so simple past tense will be appropriate in this section (“5 g of the solid were added to the solution” or “We added 5 g of the solid to the solution”).
  • Active: We heated the solution to 80°C. (The subject, “we,” performs the action, heating.)
  • Passive: The solution was heated to 80°C. (The subject, “solution,” doesn’t do the heating–it is acted upon, not acting.)

Increasingly, especially in the social sciences, using first person and active voice is acceptable in scientific reports. Most readers find that this style of writing conveys information more clearly and concisely. This rhetorical choice thus brings two scientific values into conflict: objectivity versus clarity. Since the scientific community hasn’t reached a consensus about which style it prefers, you may want to ask your lab instructor.

How do I write a strong Results section?

Here’s a paradox for you. The Results section is often both the shortest (yay!) and most important (uh-oh!) part of your report. Your Materials and Methods section shows how you obtained the results, and your Discussion section explores the significance of the results, so clearly the Results section forms the backbone of the lab report. This section provides the most critical information about your experiment: the data that allow you to discuss how your hypothesis was or wasn’t supported. But it doesn’t provide anything else, which explains why this section is generally shorter than the others.

Before you write this section, look at all the data you collected to figure out what relates significantly to your hypothesis. You’ll want to highlight this material in your Results section. Resist the urge to include every bit of data you collected, since perhaps not all are relevant. Also, don’t try to draw conclusions about the results—save them for the Discussion section. In this section, you’re reporting facts. Nothing your readers can dispute should appear in the Results section.

Most Results sections feature three distinct parts: text, tables, and figures. Let’s consider each part one at a time.

This should be a short paragraph, generally just a few lines, that describes the results you obtained from your experiment. In a relatively simple experiment, one that doesn’t produce a lot of data for you to repeat, the text can represent the entire Results section. Don’t feel that you need to include lots of extraneous detail to compensate for a short (but effective) text; your readers appreciate discrimination more than your ability to recite facts. In a more complex experiment, you may want to use tables and/or figures to help guide your readers toward the most important information you gathered. In that event, you’ll need to refer to each table or figure directly, where appropriate:

“Table 1 lists the rates of solubility for each substance”

“Solubility increased as the temperature of the solution increased (see Figure 1).”

If you do use tables or figures, make sure that you don’t present the same material in both the text and the tables/figures, since in essence you’ll just repeat yourself, probably annoying your readers with the redundancy of your statements.

Feel free to describe trends that emerge as you examine the data. Although identifying trends requires some judgment on your part and so may not feel like factual reporting, no one can deny that these trends do exist, and so they properly belong in the Results section. Example:

“Heating the solution increased the rate of solubility of polar solids by 45% but had no effect on the rate of solubility in solutions containing non-polar solids.”

This point isn’t debatable—you’re just pointing out what the data show.

As in the Materials and Methods section, you want to refer to your data in the past tense, because the events you recorded have already occurred and have finished occurring. In the example above, note the use of “increased” and “had,” rather than “increases” and “has.” (You don’t know from your experiment that heating always increases the solubility of polar solids, but it did that time.)

You shouldn’t put information in the table that also appears in the text. You also shouldn’t use a table to present irrelevant data, just to show you did collect these data during the experiment. Tables are good for some purposes and situations, but not others, so whether and how you’ll use tables depends upon what you need them to accomplish.

Tables are useful ways to show variation in data, but not to present a great deal of unchanging measurements. If you’re dealing with a scientific phenomenon that occurs only within a certain range of temperatures, for example, you don’t need to use a table to show that the phenomenon didn’t occur at any of the other temperatures. How useful is this table?

A table labeled Effect of Temperature on Rate of Solubility with temperature of solvent values in 10-degree increments from -20 degrees Celsius to 80 degrees Celsius that does not show a corresponding rate of solubility value until 50 degrees Celsius.

As you can probably see, no solubility was observed until the trial temperature reached 50°C, a fact that the text part of the Results section could easily convey. The table could then be limited to what happened at 50°C and higher, thus better illustrating the differences in solubility rates when solubility did occur.

As a rule, try not to use a table to describe any experimental event you can cover in one sentence of text. Here’s an example of an unnecessary table from How to Write and Publish a Scientific Paper , by Robert A. Day:

A table labeled Oxygen requirements of various species of Streptomyces showing the names of organisms and two columns that indicate growth under aerobic conditions and growth under anaerobic conditions with a plus or minus symbol for each organism in the growth columns to indicate value.

As Day notes, all the information in this table can be summarized in one sentence: “S. griseus, S. coelicolor, S. everycolor, and S. rainbowenski grew under aerobic conditions, whereas S. nocolor and S. greenicus required anaerobic conditions.” Most readers won’t find the table clearer than that one sentence.

When you do have reason to tabulate material, pay attention to the clarity and readability of the format you use. Here are a few tips:

  • Number your table. Then, when you refer to the table in the text, use that number to tell your readers which table they can review to clarify the material.
  • Give your table a title. This title should be descriptive enough to communicate the contents of the table, but not so long that it becomes difficult to follow. The titles in the sample tables above are acceptable.
  • Arrange your table so that readers read vertically, not horizontally. For the most part, this rule means that you should construct your table so that like elements read down, not across. Think about what you want your readers to compare, and put that information in the column (up and down) rather than in the row (across). Usually, the point of comparison will be the numerical data you collect, so especially make sure you have columns of numbers, not rows.Here’s an example of how drastically this decision affects the readability of your table (from A Short Guide to Writing about Chemistry , by Herbert Beall and John Trimbur). Look at this table, which presents the relevant data in horizontal rows:

A table labeled Boyle's Law Experiment: Measuring Volume as a Function of Pressure that presents the trial number, length of air sample in millimeters, and height difference in inches of mercury, each of which is presented in rows horizontally.

It’s a little tough to see the trends that the author presumably wants to present in this table. Compare this table, in which the data appear vertically:

A table labeled Boyle's Law Experiment: Measuring Volume as a Function of Pressure that presents the trial number, length of air sample in millimeters, and height difference in inches of mercury, each of which is presented in columns vertically.

The second table shows how putting like elements in a vertical column makes for easier reading. In this case, the like elements are the measurements of length and height, over five trials–not, as in the first table, the length and height measurements for each trial.

  • Make sure to include units of measurement in the tables. Readers might be able to guess that you measured something in millimeters, but don’t make them try.
  • Don’t use vertical lines as part of the format for your table. This convention exists because journals prefer not to have to reproduce these lines because the tables then become more expensive to print. Even though it’s fairly unlikely that you’ll be sending your Biology 11 lab report to Science for publication, your readers still have this expectation. Consequently, if you use the table-drawing option in your word-processing software, choose the option that doesn’t rely on a “grid” format (which includes vertical lines).

How do I include figures in my report?

Although tables can be useful ways of showing trends in the results you obtained, figures (i.e., illustrations) can do an even better job of emphasizing such trends. Lab report writers often use graphic representations of the data they collected to provide their readers with a literal picture of how the experiment went.

When should you use a figure?

Remember the circumstances under which you don’t need a table: when you don’t have a great deal of data or when the data you have don’t vary a lot. Under the same conditions, you would probably forgo the figure as well, since the figure would be unlikely to provide your readers with an additional perspective. Scientists really don’t like their time wasted, so they tend not to respond favorably to redundancy.

If you’re trying to decide between using a table and creating a figure to present your material, consider the following a rule of thumb. The strength of a table lies in its ability to supply large amounts of exact data, whereas the strength of a figure is its dramatic illustration of important trends within the experiment. If you feel that your readers won’t get the full impact of the results you obtained just by looking at the numbers, then a figure might be appropriate.

Of course, an undergraduate class may expect you to create a figure for your lab experiment, if only to make sure that you can do so effectively. If this is the case, then don’t worry about whether to use figures or not—concentrate instead on how best to accomplish your task.

Figures can include maps, photographs, pen-and-ink drawings, flow charts, bar graphs, and section graphs (“pie charts”). But the most common figure by far, especially for undergraduates, is the line graph, so we’ll focus on that type in this handout.

At the undergraduate level, you can often draw and label your graphs by hand, provided that the result is clear, legible, and drawn to scale. Computer technology has, however, made creating line graphs a lot easier. Most word-processing software has a number of functions for transferring data into graph form; many scientists have found Microsoft Excel, for example, a helpful tool in graphing results. If you plan on pursuing a career in the sciences, it may be well worth your while to learn to use a similar program.

Computers can’t, however, decide for you how your graph really works; you have to know how to design your graph to meet your readers’ expectations. Here are some of these expectations:

  • Keep it as simple as possible. You may be tempted to signal the complexity of the information you gathered by trying to design a graph that accounts for that complexity. But remember the purpose of your graph: to dramatize your results in a manner that’s easy to see and grasp. Try not to make the reader stare at the graph for a half hour to find the important line among the mass of other lines. For maximum effectiveness, limit yourself to three to five lines per graph; if you have more data to demonstrate, use a set of graphs to account for it, rather than trying to cram it all into a single figure.
  • Plot the independent variable on the horizontal (x) axis and the dependent variable on the vertical (y) axis. Remember that the independent variable is the condition that you manipulated during the experiment and the dependent variable is the condition that you measured to see if it changed along with the independent variable. Placing the variables along their respective axes is mostly just a convention, but since your readers are accustomed to viewing graphs in this way, you’re better off not challenging the convention in your report.
  • Label each axis carefully, and be especially careful to include units of measure. You need to make sure that your readers understand perfectly well what your graph indicates.
  • Number and title your graphs. As with tables, the title of the graph should be informative but concise, and you should refer to your graph by number in the text (e.g., “Figure 1 shows the increase in the solubility rate as a function of temperature”).
  • Many editors of professional scientific journals prefer that writers distinguish the lines in their graphs by attaching a symbol to them, usually a geometric shape (triangle, square, etc.), and using that symbol throughout the curve of the line. Generally, readers have a hard time distinguishing dotted lines from dot-dash lines from straight lines, so you should consider staying away from this system. Editors don’t usually like different-colored lines within a graph because colors are difficult and expensive to reproduce; colors may, however, be great for your purposes, as long as you’re not planning to submit your paper to Nature. Use your discretion—try to employ whichever technique dramatizes the results most effectively.
  • Try to gather data at regular intervals, so the plot points on your graph aren’t too far apart. You can’t be sure of the arc you should draw between the plot points if the points are located at the far corners of the graph; over a fifteen-minute interval, perhaps the change occurred in the first or last thirty seconds of that period (in which case your straight-line connection between the points is misleading).
  • If you’re worried that you didn’t collect data at sufficiently regular intervals during your experiment, go ahead and connect the points with a straight line, but you may want to examine this problem as part of your Discussion section.
  • Make your graph large enough so that everything is legible and clearly demarcated, but not so large that it either overwhelms the rest of the Results section or provides a far greater range than you need to illustrate your point. If, for example, the seedlings of your plant grew only 15 mm during the trial, you don’t need to construct a graph that accounts for 100 mm of growth. The lines in your graph should more or less fill the space created by the axes; if you see that your data is confined to the lower left portion of the graph, you should probably re-adjust your scale.
  • If you create a set of graphs, make them the same size and format, including all the verbal and visual codes (captions, symbols, scale, etc.). You want to be as consistent as possible in your illustrations, so that your readers can easily make the comparisons you’re trying to get them to see.

How do I write a strong Discussion section?

The discussion section is probably the least formalized part of the report, in that you can’t really apply the same structure to every type of experiment. In simple terms, here you tell your readers what to make of the Results you obtained. If you have done the Results part well, your readers should already recognize the trends in the data and have a fairly clear idea of whether your hypothesis was supported. Because the Results can seem so self-explanatory, many students find it difficult to know what material to add in this last section.

Basically, the Discussion contains several parts, in no particular order, but roughly moving from specific (i.e., related to your experiment only) to general (how your findings fit in the larger scientific community). In this section, you will, as a rule, need to:

Explain whether the data support your hypothesis

  • Acknowledge any anomalous data or deviations from what you expected

Derive conclusions, based on your findings, about the process you’re studying

  • Relate your findings to earlier work in the same area (if you can)

Explore the theoretical and/or practical implications of your findings

Let’s look at some dos and don’ts for each of these objectives.

This statement is usually a good way to begin the Discussion, since you can’t effectively speak about the larger scientific value of your study until you’ve figured out the particulars of this experiment. You might begin this part of the Discussion by explicitly stating the relationships or correlations your data indicate between the independent and dependent variables. Then you can show more clearly why you believe your hypothesis was or was not supported. For example, if you tested solubility at various temperatures, you could start this section by noting that the rates of solubility increased as the temperature increased. If your initial hypothesis surmised that temperature change would not affect solubility, you would then say something like,

“The hypothesis that temperature change would not affect solubility was not supported by the data.”

Note: Students tend to view labs as practical tests of undeniable scientific truths. As a result, you may want to say that the hypothesis was “proved” or “disproved” or that it was “correct” or “incorrect.” These terms, however, reflect a degree of certainty that you as a scientist aren’t supposed to have. Remember, you’re testing a theory with a procedure that lasts only a few hours and relies on only a few trials, which severely compromises your ability to be sure about the “truth” you see. Words like “supported,” “indicated,” and “suggested” are more acceptable ways to evaluate your hypothesis.

Also, recognize that saying whether the data supported your hypothesis or not involves making a claim to be defended. As such, you need to show the readers that this claim is warranted by the evidence. Make sure that you’re very explicit about the relationship between the evidence and the conclusions you draw from it. This process is difficult for many writers because we don’t often justify conclusions in our regular lives. For example, you might nudge your friend at a party and whisper, “That guy’s drunk,” and once your friend lays eyes on the person in question, she might readily agree. In a scientific paper, by contrast, you would need to defend your claim more thoroughly by pointing to data such as slurred words, unsteady gait, and the lampshade-as-hat. In addition to pointing out these details, you would also need to show how (according to previous studies) these signs are consistent with inebriation, especially if they occur in conjunction with one another. To put it another way, tell your readers exactly how you got from point A (was the hypothesis supported?) to point B (yes/no).

Acknowledge any anomalous data, or deviations from what you expected

You need to take these exceptions and divergences into account, so that you qualify your conclusions sufficiently. For obvious reasons, your readers will doubt your authority if you (deliberately or inadvertently) overlook a key piece of data that doesn’t square with your perspective on what occurred. In a more philosophical sense, once you’ve ignored evidence that contradicts your claims, you’ve departed from the scientific method. The urge to “tidy up” the experiment is often strong, but if you give in to it you’re no longer performing good science.

Sometimes after you’ve performed a study or experiment, you realize that some part of the methods you used to test your hypothesis was flawed. In that case, it’s OK to suggest that if you had the chance to conduct your test again, you might change the design in this or that specific way in order to avoid such and such a problem. The key to making this approach work, though, is to be very precise about the weakness in your experiment, why and how you think that weakness might have affected your data, and how you would alter your protocol to eliminate—or limit the effects of—that weakness. Often, inexperienced researchers and writers feel the need to account for “wrong” data (remember, there’s no such animal), and so they speculate wildly about what might have screwed things up. These speculations include such factors as the unusually hot temperature in the room, or the possibility that their lab partners read the meters wrong, or the potentially defective equipment. These explanations are what scientists call “cop-outs,” or “lame”; don’t indicate that the experiment had a weakness unless you’re fairly certain that a) it really occurred and b) you can explain reasonably well how that weakness affected your results.

If, for example, your hypothesis dealt with the changes in solubility at different temperatures, then try to figure out what you can rationally say about the process of solubility more generally. If you’re doing an undergraduate lab, chances are that the lab will connect in some way to the material you’ve been covering either in lecture or in your reading, so you might choose to return to these resources as a way to help you think clearly about the process as a whole.

This part of the Discussion section is another place where you need to make sure that you’re not overreaching. Again, nothing you’ve found in one study would remotely allow you to claim that you now “know” something, or that something isn’t “true,” or that your experiment “confirmed” some principle or other. Hesitate before you go out on a limb—it’s dangerous! Use less absolutely conclusive language, including such words as “suggest,” “indicate,” “correspond,” “possibly,” “challenge,” etc.

Relate your findings to previous work in the field (if possible)

We’ve been talking about how to show that you belong in a particular community (such as biologists or anthropologists) by writing within conventions that they recognize and accept. Another is to try to identify a conversation going on among members of that community, and use your work to contribute to that conversation. In a larger philosophical sense, scientists can’t fully understand the value of their research unless they have some sense of the context that provoked and nourished it. That is, you have to recognize what’s new about your project (potentially, anyway) and how it benefits the wider body of scientific knowledge. On a more pragmatic level, especially for undergraduates, connecting your lab work to previous research will demonstrate to the TA that you see the big picture. You have an opportunity, in the Discussion section, to distinguish yourself from the students in your class who aren’t thinking beyond the barest facts of the study. Capitalize on this opportunity by putting your own work in context.

If you’re just beginning to work in the natural sciences (as a first-year biology or chemistry student, say), most likely the work you’ll be doing has already been performed and re-performed to a satisfactory degree. Hence, you could probably point to a similar experiment or study and compare/contrast your results and conclusions. More advanced work may deal with an issue that is somewhat less “resolved,” and so previous research may take the form of an ongoing debate, and you can use your own work to weigh in on that debate. If, for example, researchers are hotly disputing the value of herbal remedies for the common cold, and the results of your study suggest that Echinacea diminishes the symptoms but not the actual presence of the cold, then you might want to take some time in the Discussion section to recapitulate the specifics of the dispute as it relates to Echinacea as an herbal remedy. (Consider that you have probably already written in the Introduction about this debate as background research.)

This information is often the best way to end your Discussion (and, for all intents and purposes, the report). In argumentative writing generally, you want to use your closing words to convey the main point of your writing. This main point can be primarily theoretical (“Now that you understand this information, you’re in a better position to understand this larger issue”) or primarily practical (“You can use this information to take such and such an action”). In either case, the concluding statements help the reader to comprehend the significance of your project and your decision to write about it.

Since a lab report is argumentative—after all, you’re investigating a claim, and judging the legitimacy of that claim by generating and collecting evidence—it’s often a good idea to end your report with the same technique for establishing your main point. If you want to go the theoretical route, you might talk about the consequences your study has for the field or phenomenon you’re investigating. To return to the examples regarding solubility, you could end by reflecting on what your work on solubility as a function of temperature tells us (potentially) about solubility in general. (Some folks consider this type of exploration “pure” as opposed to “applied” science, although these labels can be problematic.) If you want to go the practical route, you could end by speculating about the medical, institutional, or commercial implications of your findings—in other words, answer the question, “What can this study help people to do?” In either case, you’re going to make your readers’ experience more satisfying, by helping them see why they spent their time learning what you had to teach them.

Writing an Introduction for a Scientific Paper

Dr. michelle harris, dr. janet batzli, biocore.

This section provides guidelines on how to construct a solid introduction to a scientific paper including background information, study question , biological rationale, hypothesis , and general approach . If the Introduction is done well, there should be no question in the reader’s mind why and on what basis you have posed a specific hypothesis.

Broad Question : based on an initial observation (e.g., “I see a lot of guppies close to the shore. Do guppies like living in shallow water?”). This observation of the natural world may inspire you to investigate background literature or your observation could be based on previous research by others or your own pilot study. Broad questions are not always included in your written text, but are essential for establishing the direction of your research.

Background Information : key issues, concepts, terminology, and definitions needed to understand the biological rationale for the experiment. It often includes a summary of findings from previous, relevant studies. Remember to cite references, be concise, and only include relevant information given your audience and your experimental design. Concisely summarized background information leads to the identification of specific scientific knowledge gaps that still exist. (e.g., “No studies to date have examined whether guppies do indeed spend more time in shallow water.”)

Testable Question : these questions are much more focused than the initial broad question, are specific to the knowledge gap identified, and can be addressed with data. (e.g., “Do guppies spend different amounts of time in water <1 meter deep as compared to their time in water that is >1 meter deep?”)

Biological Rationale : describes the purpose of your experiment distilling what is known and what is not known that defines the knowledge gap that you are addressing. The “BR” provides the logic for your hypothesis and experimental approach, describing the biological mechanism and assumptions that explain why your hypothesis should be true.

The biological rationale is based on your interpretation of the scientific literature, your personal observations, and the underlying assumptions you are making about how you think the system works. If you have written your biological rationale, your reader should see your hypothesis in your introduction section and say to themselves, “Of course, this hypothesis seems very logical based on the rationale presented.”

  • A thorough rationale defines your assumptions about the system that have not been revealed in scientific literature or from previous systematic observation. These assumptions drive the direction of your specific hypothesis or general predictions.
  • Defining the rationale is probably the most critical task for a writer, as it tells your reader why your research is biologically meaningful. It may help to think about the rationale as an answer to the questions— how is this investigation related to what we know, what assumptions am I making about what we don’t yet know, AND how will this experiment add to our knowledge? *There may or may not be broader implications for your study; be careful not to overstate these (see note on social justifications below).
  • Expect to spend time and mental effort on this. You may have to do considerable digging into the scientific literature to define how your experiment fits into what is already known and why it is relevant to pursue.
  • Be open to the possibility that as you work with and think about your data, you may develop a deeper, more accurate understanding of the experimental system. You may find the original rationale needs to be revised to reflect your new, more sophisticated understanding.
  • As you progress through Biocore and upper level biology courses, your rationale should become more focused and matched with the level of study e ., cellular, biochemical, or physiological mechanisms that underlie the rationale. Achieving this type of understanding takes effort, but it will lead to better communication of your science.

***Special note on avoiding social justifications: You should not overemphasize the relevance of your experiment and the possible connections to large-scale processes. Be realistic and logical —do not overgeneralize or state grand implications that are not sensible given the structure of your experimental system. Not all science is easily applied to improving the human condition. Performing an investigation just for the sake of adding to our scientific knowledge (“pure or basic science”) is just as important as applied science. In fact, basic science often provides the foundation for applied studies.

Hypothesis / Predictions : specific prediction(s) that you will test during your experiment. For manipulative experiments, the hypothesis should include the independent variable (what you manipulate), the dependent variable(s) (what you measure), the organism or system , the direction of your results, and comparison to be made.

If you are doing a systematic observation , your hypothesis presents a variable or set of variables that you predict are important for helping you characterize the system as a whole, or predict differences between components/areas of the system that help you explain how the system functions or changes over time.

Experimental Approach : Briefly gives the reader a general sense of the experiment, the type of data it will yield, and the kind of conclusions you expect to obtain from the data. Do not confuse the experimental approach with the experimental protocol . The experimental protocol consists of the detailed step-by-step procedures and techniques used during the experiment that are to be reported in the Methods and Materials section.

Some Final Tips on Writing an Introduction

  • As you progress through the Biocore sequence, for instance, from organismal level of Biocore 301/302 to the cellular level in Biocore 303/304, we expect the contents of your “Introduction” paragraphs to reflect the level of your coursework and previous writing experience. For example, in Biocore 304 (Cell Biology Lab) biological rationale should draw upon assumptions we are making about cellular and biochemical processes.
  • Be Concise yet Specific: Remember to be concise and only include relevant information given your audience and your experimental design. As you write, keep asking, “Is this necessary information or is this irrelevant detail?” For example, if you are writing a paper claiming that a certain compound is a competitive inhibitor to the enzyme alkaline phosphatase and acts by binding to the active site, you need to explain (briefly) Michaelis-Menton kinetics and the meaning and significance of Km and Vmax. This explanation is not necessary if you are reporting the dependence of enzyme activity on pH because you do not need to measure Km and Vmax to get an estimate of enzyme activity.
  • Another example: if you are writing a paper reporting an increase in Daphnia magna heart rate upon exposure to caffeine you need not describe the reproductive cycle of magna unless it is germane to your results and discussion. Be specific and concrete, especially when making introductory or summary statements.

Where Do You Discuss Pilot Studies? Many times it is important to do pilot studies to help you get familiar with your experimental system or to improve your experimental design. If your pilot study influences your biological rationale or hypothesis, you need to describe it in your Introduction. If your pilot study simply informs the logistics or techniques, but does not influence your rationale, then the description of your pilot study belongs in the Materials and Methods section.  

How will introductions be evaluated? The following is part of the rubric we will be using to evaluate your papers.

How to write a scientific report at university

David foster, professor in science and engineering at the university of manchester, explains the best way to write a successful scientific report.

David H Foster's avatar

At university, you might need to write scientific reports for laboratory experiments, computing and theoretical projects, and literature-based studies – and some eventually as research dissertations. All have a similar structure modelled on scientific journal articles. Their special format helps readers to navigate, understand and make comparisons across the research field.

Scientific report structure

The main components are similar for many subject areas, though some sections might be optional.

If you can choose a title, make it informative and not more than around 12 words. This is the average for scientific articles. Make every word count.  

The abstract summarises your report’s content in a restricted word limit. It might be read separately from your full report, so it should contain a micro-report, without references or personalisation.  

Usual elements you can include:  

  • Some background to the research area.
  • Reason for the work.
  • Main results.
  • Any implications.

Ensure you omit empty statements such as “results are discussed”, as they usually are.  

Introduction  

The introduction should give enough background for readers to assess your work without consulting previous publications.  

It can be organised along these lines:  

  • An opening statement to set the context.  
  • A summary of relevant published research.
  • Your research question, hypothesis or other motivation.  
  • The purpose of your work.
  • An indication of methodology.
  • Your outcome.

Choose citations to any previous research carefully. They should reflect priority and importance, not necessarily recency. Your choices signal your grasp of the field.  

Literature review  

Dissertations and literature-based studies demand a more comprehensive review of published research than is summarised in the introduction. Fortunately, you don’t need to examine thousands of articles. Just proceed systematically.  

  • Use two to three published reviews to familiarise yourself with the field.  
  • Use authoritative databases such as Scopus or Web of Science to find the most frequently cited articles.  
  • Read these articles, noting key points. Experiment with their order and then turn them into sentences, in your own words.  
  • Get advice about expected review length and database usage from your individual programme.

Aims and objectives  

Although the introduction describes the purpose of your work, dissertations might require something more accountable, with distinct aims and objectives.

The aim or aims represent the overall goal (for example, to land people on the moon). The objectives are the individual tasks that together achieve this goal (build rocket, recruit volunteers, launch rocket and so on).

The method section must give enough detail for a competent researcher to repeat your work. Technical descriptions should be accessible, so use generic names for equipment with proprietary names in parentheses (model, year, manufacturer, for example). Ensure that essential steps are clear, especially any affecting your conclusions.

The results section should contain mainly data and analysis. Start with a sentence or two to orient your reader. For numeric data, use graphs over tables and try to make graphs self-explanatory. Leave any interpretations for the discussion section.

The purpose of the discussion is to say what your results mean. Useful items to include:  

  • A reminder of the reason for the work.
  • A review of the results. Ensure you are not repeating the results themselves; this should be more about your thoughts on them.
  • The relationship between your results and the original objective.
  • Their relationship to the literature, with citations.  
  • Any limitations of your results.  
  • Any knowledge you gained, new questions or longer-term implications.

The last item might form a concluding paragraph or be placed in a separate conclusion section. If your report is an internal document, ensure you only refer to your future research plans.  

Try to finish with a “take-home” message complementing the opening of your introduction. For example: “This analysis has shown the process is feasible, but cost will decide its acceptability.”

Acknowledgements  

If appropriate, thank colleagues for advice, reading your report and technical support. Make sure that you secure their agreement first. Thank any funding agency. Avoid emotional declarations that you might later regret. That is all that is required in this section.  

Referencing  

Giving references ensures other authors’ ideas, procedures, results and inferences are credited. Use Web of Science or Scopus as mentioned earlier. Avoid databases giving online sources without journal publication details because they might be unreliable.

Don’t refer to Wikipedia. It isn’t a citable source.  

Use one referencing style consistently and make sure it matches the required style of your degree or department. Choose either numbers or author and year to refer to the full references listed near the end of your report. Include all publication details, not just website links. Every reference should be cited in the text.  

Figures and tables  

Each figure should have a caption below with a label, such as “Fig. 1”, with a title and a sentence or two about what it shows. Similarly for tables, except that the title appears above. Every figure and table should be cited in the text.

Theoretical studies  

More flexibility is possible with theoretical reports, but extra care is needed with logical development and mathematical presentation. An introduction and discussion are still needed, and possibly a literature review.

Final steps

Check that your report satisfies the formatting requirements of your department or degree programme. Check for grammatical errors, misspellings, informal language, punctuation, typos and repetition or omission.

Ask fellow students to read your report critically. Then rewrite it. Put it aside for a few days and read it afresh, making any new edits you’ve noticed. Keep up this process until you are happy with the final report.

Defining a Report

A report is a type of writing that represents information, data, and research findings on a specific topic. The writer is expected to deliver a well-structured, credible, and informative text that dives into the small details of a certain topic, discussing its benefits and challenges.

Reports serve many important purposes. They provide recorded facts and findings. They are used to analyze data and draw insights that can be used for decision-making. Some reports serve as compliance checks to ensure that organizations meet certain standards and requirements. Also, reports are a formal way to communicate valuable information to decision-makers and stakeholders.

A report paper can be academic or about sales, science, business, etc. But unlike other texts, report writing takes much more than getting acquainted with the subject and forming an opinion about it. Report preparation is the most important stage of the writing process. Whether you are assigned to write an academic or a sales paper, before you start writing, you must do thorough research on the topic and ensure that every source of information is trustworthy.

Report writing has its rules. In this article, we will cover everything from how to start a report to how to format one. Below you will find a student research report sample. Check our paper writer service if you want one designed specifically for your requirements.

Student Research Report Sample

Explore and learn more about comprehensive but concise reports.

What are the Report Types

As mentioned, there are plenty of different types of report papers. Even though they are very formal, academic reports are only one of many people will come across in their lifetime. Some reports concentrate on the annual performance of a company, some on a project's progress, and others on scientific findings.

Next, we will elaborate more on different sorts of reports, their contents, and their purpose. Don't forget to also check out our report example that you can find below.

report types

Academic Reports

An academic report represents supported data and information about a particular subject. This could be a historical event, a book, or a scientific finding. The credibility of such academic writing is very important as it, in the future, could be used as a backup for dissertations, essays, and other academic work.

Students are often assigned to write reports to test their understanding of a topic. They also provide evidence of the student's ability to critically analyze and synthesize information. It also demonstrates the student's writing skills and ability to simply convey complex findings and ideas.

Remember that the report outline will affect your final grade when writing an academic report. If you want to learn about the correct report writing format, keep reading the article. If you want to save time, you can always buy essays online .

Project Reports

Every project has numerous stakeholders who like to keep an eye on how things are going. This can be challenging if the number of people who need to be kept in the loop is high. One way to ensure everyone is updated and on the same page is periodic project reports.

Project managers are often assigned to make a report for people that affect the project's fate. It is a detailed document that summarizes the work done during the project and the work that needs to be completed. It informs about deadlines and helps form coherent expectations. Previous reports can be used as a reference point as the project progresses.

Sales Reports

Sales reports are excellent ways to keep your team updated on your sales strategies. It provides significant information to stakeholders, including managers, investors, and executives, so they can make informed decisions about the direction of their business.

A sales report usually provides information about a company's sales performance over a precise period. These reports include information about the revenue generated, the total number of units sold, and other metrics that help the company define the success of sales performance.

Sales report preparation is a meticulous job. To communicate information engagingly, you can put together graphs showing various information, including engagement increase, profit margins, and more.

Business Reports

If you were assigned a business report, something tells us you are wondering how to write a report for work. Let us tell you that the strategy is not much different from writing an academic report. A Strong thesis statement, compelling storytelling, credible sources, and correct format are all that matter.

Business reports can take many forms, such as marketing reports, operational reports, market research reports, feasible studies, and more. The purpose of such report writing is to provide analysis and recommendations to support decision-making and help shape a company's future strategy.

Most business reports include charts, graphs, and other visual aids that help illustrate key points and make complex information easy to digest. 

Scientific Reports

Scientific reports present the results of scientific research or investigation to a specific audience. Unlike book reports, a scientific report is always reviewed by other experts in the field for its accuracy, quality, and relevance.

If you are a scientist or a science student, you can't escape writing a lab report. You will need to provide background information on the research topic and explain the study's purpose. A scientific report includes a discussion part where the researcher interprets the results and significance of the study.

Whether you are assigned to write medical reports or make a report about new findings in the field of physics, your writing should always have an introduction, methodology, results, conclusion, and references. These are the foundation of a well-written report.

Annual Reports

An annual report is a comprehensive piece of writing that provides information about a company's performance over a year. In its nature, it might remind us of extended financial reports.

Annual reports represent types of longer reports. They usually include an overview of a company's activities, a financial summary, detailed product and service information, and market conditions. But it's not just a report of the company's performance in the sales market, but also an overview of its social responsibility programs and sustainability activities.

The format of annual report writing depends on the company's specific requirements, the needs of its stakeholder, and the regulation of the country it's based.

Writing Reports Are Not Your Thing?

Our professional writers will get you any report type meeting your requirements in no time

Report Format

As we've seen throughout this article, various types of reports exist. And even though their content differs, they share one essential element: report writing format. Structure, research methods, grammar, and reference lists are equally important to different reports.

Keep in mind that while the general format is the same for every type, you still need to check the requirements of the assigned report before writing one. School reports, lab reports, and financial reports are three different types of the same category.

We are now moving on to discuss the general report format. Let's direct our attention to how to start a report.

Title : You need a comprehensive but concise title to set the right tone and make a good impression. It should be reflective of the general themes in the report.

Table of Contents : Your title page must be followed by a table of contents. We suggest writing an entire report first and creating a table of content later.

Summary : The table of contents should be followed by an executive report summary. To create a comprehensive summary, wait until you have finished writing the full report.

Introduction : A major part of the report structure is an introduction. Make sure you convey the main idea of the report in just a few words. The introduction section must also include a strong thesis statement.

Body : The central part of your work is called the report's body. Here you should present relevant information and provide supported evidence. Make sure every paragraph starts with a topic sentence. Here you can use bullet points, graphs, and other visual aids.

Conclusion : Use this part to summarize your findings and focus on the main elements and what they bring to the table. Do not introduce new ideas. Good report writing means knowing the difference between a summary and a conclusion.

Recommendations : A report is designed to help decision-makers or provide crucial information to the conversation, including a set of goals or steps that should be taken to further advance the progress.

Appendices : As a finishing touch, include a list of source materials on which you based the information and facts. If you want your report to get acknowledged, don't neglect this part of the report format.

How to Write a Report Like a PRO

Mastering the report writing format is only a fraction of the job. Writing an exceptional report takes more than just including a title page and references.

Next, we will offer report-writing tips to help you figure out how to write a report like a PRO. Meanwhile, if you need someone to review your physics homework, our physics helper is ready to take on the job.

Start With a Strong Thesis

A strong thesis is essential to a good paper because it sets the direction for the rest. It should provide a well-defined but short summary of the main points and arguments made in the report.

A strong thesis can help you collect your thoughts and ensure that the report has a course and a coherent structure. It will help you stay focused on key points and tie every paragraph into one entity.

A clear thesis will make your report writing sound more confident and persuasive. It will make finding supporting evidence easier, and you will be able to effectively communicate your ideas to the reader.

Use Simple Wording

Reports are there to gather and distribute as much information to as many people as possible. So, the content of it should be accessible and understandable for everyone, despite their knowledge in the field. We encourage you to use simple words instead of fancy ones when writing reports for large audiences.

Other academic papers might require you to showcase advanced language knowledge and extensive vocabulary. Still, formal reports should present information in a way that does not confuse.

If you are wondering how to make report that is easy to read and digest, try finding simpler alternatives to fancy words. For example, use 'example' instead of 'paradigm'; Use 'relevant' instead of 'pertinent'; 'Exacerbate' is a fancier way to say 'worsen,' and while it makes you look educated, it might cause confusion and make you lose the reader. Choose words that are easier to understand.

Present Only One Concept in Each Phrase

Make your reports easier to understand by presenting only one concept in each paragraph. Simple, short sentences save everyone's time and make complex concepts easier to digest and memorize. 

Report writing is not a single-use material. It will be reread and re-used many times. Someone else might use your sales report to support their financial report. So, to avoid confusion and misinterpretation, start each paragraph with a topic sentence and tie everything else into this main theme.

Only Present Reliable Facts

You might have a strong hunch about future events or outcomes, but a research report is not a place to voice them. Everything you write should be supported by undisputed evidence.

Don't forget that one of the essential report preparation steps is conducting thorough research. Limit yourself to the information which is based on credible information. Only present relevant facts to the topic and add value to your thesis.

One of our report writing tips would be to write a rough draft and eliminate all the information not supported by reliable data. Double-check the credibility of the sources before finalizing the writing process.

Incorporate Bullet Points

When writing a research report, your goal is to make the information as consumable as possible. Don't shy away from using visual aids; this will only help you connect with a wider audience.

Bullet points are a great way to simplify the reading process and draw attention to the main concepts of the report. Use this technique in the body part of the report. If you notice that you are writing related information, use bullet points to point out their relation.

Incorporating bullet points and other visual aids in your report writing format will make a report easy to comprehend and use for further research.

While you are busy coming up with effective visual aids, you may not have enough time to take care of other assignments. Simply say, ' write my argumentative essay ,' and one of our expert writers will answer your prayer.

Review the Text for Accuracy and Inconsistencies

After completing report preparation and writing, ensure you don't skip the final stage. Even the greatest writers are not immune to grammatical mistakes and factual mix-ups.

Reviewing what you wrote is just as important as the research stage. Make sure there are no inconsistencies, and everything smoothly ties into the bigger scheme of events. Look out for spelling mistakes and word count.

Writing a "good" results section

Figures and Captions in Lab Reports

"Results Checklist" from: How to Write a Good Scientific Paper. Chris A. Mack. SPIE. 2018.

Additional tips for results sections.

  • LITERATURE CITED
  • Bibliography of guides to scientific writing and presenting
  • Peer Review
  • Presentations
  • Lab Report Writing Guides on the Web

This is the core of the paper. Don't start the results sections with methods you left out of the Materials and Methods section. You need to give an overall description of the experiments and present the data you found.

  • Factual statements supported by evidence. Short and sweet without excess words
  • Present representative data rather than endlessly repetitive data
  • Discuss variables only if they had an effect (positive or negative)
  • Use meaningful statistics
  • Avoid redundancy. If it is in the tables or captions you may not need to repeat it

A short article by Dr. Brett Couch and Dr. Deena Wassenberg, Biology Program, University of Minnesota

  • Present the results of the paper, in logical order, using tables and graphs as necessary.
  • Explain the results and show how they help to answer the research questions posed in the Introduction. Evidence does not explain itself; the results must be presented and then explained. 
  • Avoid: presenting results that are never discussed;  presenting results in chronological order rather than logical order; ignoring results that do not support the conclusions; 
  • Number tables and figures separately beginning with 1 (i.e. Table 1, Table 2, Figure 1, etc.).
  • Do not attempt to evaluate the results in this section. Report only what you found; hold all discussion of the significance of the results for the Discussion section.
  • It is not necessary to describe every step of your statistical analyses. Scientists understand all about null hypotheses, rejection rules, and so forth and do not need to be reminded of them. Just say something like, "Honeybees did not use the flowers in proportion to their availability (X2 = 7.9, p<0.05, d.f.= 4, chi-square test)." Likewise, cite tables and figures without describing in detail how the data were manipulated. Explanations of this sort should appear in a legend or caption written on the same page as the figure or table.
  • You must refer in the text to each figure or table you include in your paper.
  • Tables generally should report summary-level data, such as means ± standard deviations, rather than all your raw data.  A long list of all your individual observations will mean much less than a few concise, easy-to-read tables or figures that bring out the main findings of your study.  
  • Only use a figure (graph) when the data lend themselves to a good visual representation.  Avoid using figures that show too many variables or trends at once, because they can be hard to understand.

How to Write Discussions and Conclusions

The discussion section contains the results and outcomes of a study. An effective discussion informs readers what can be learned from your experiment and provides context for the results.

What makes an effective discussion?

When you’re ready to write your discussion, you’ve already introduced the purpose of your study and provided an in-depth description of the methodology. The discussion informs readers about the larger implications of your study based on the results. Highlighting these implications while not overstating the findings can be challenging, especially when you’re submitting to a journal that selects articles based on novelty or potential impact. Regardless of what journal you are submitting to, the discussion section always serves the same purpose: concluding what your study results actually mean.

A successful discussion section puts your findings in context. It should include:

  • the results of your research,
  • a discussion of related research, and
  • a comparison between your results and initial hypothesis.

Tip: Not all journals share the same naming conventions.

You can apply the advice in this article to the conclusion, results or discussion sections of your manuscript.

Our Early Career Researcher community tells us that the conclusion is often considered the most difficult aspect of a manuscript to write. To help, this guide provides questions to ask yourself, a basic structure to model your discussion off of and examples from published manuscripts. 

scientific report essay example

Questions to ask yourself:

  • Was my hypothesis correct?
  • If my hypothesis is partially correct or entirely different, what can be learned from the results? 
  • How do the conclusions reshape or add onto the existing knowledge in the field? What does previous research say about the topic? 
  • Why are the results important or relevant to your audience? Do they add further evidence to a scientific consensus or disprove prior studies? 
  • How can future research build on these observations? What are the key experiments that must be done? 
  • What is the “take-home” message you want your reader to leave with?

How to structure a discussion

Trying to fit a complete discussion into a single paragraph can add unnecessary stress to the writing process. If possible, you’ll want to give yourself two or three paragraphs to give the reader a comprehensive understanding of your study as a whole. Here’s one way to structure an effective discussion:

Writing Tips

While the above sections can help you brainstorm and structure your discussion, there are many common mistakes that writers revert to when having difficulties with their paper. Writing a discussion can be a delicate balance between summarizing your results, providing proper context for your research and avoiding introducing new information. Remember that your paper should be both confident and honest about the results! 

What to do

  • Read the journal’s guidelines on the discussion and conclusion sections. If possible, learn about the guidelines before writing the discussion to ensure you’re writing to meet their expectations. 
  • Begin with a clear statement of the principal findings. This will reinforce the main take-away for the reader and set up the rest of the discussion. 
  • Explain why the outcomes of your study are important to the reader. Discuss the implications of your findings realistically based on previous literature, highlighting both the strengths and limitations of the research. 
  • State whether the results prove or disprove your hypothesis. If your hypothesis was disproved, what might be the reasons? 
  • Introduce new or expanded ways to think about the research question. Indicate what next steps can be taken to further pursue any unresolved questions. 
  • If dealing with a contemporary or ongoing problem, such as climate change, discuss possible consequences if the problem is avoided. 
  • Be concise. Adding unnecessary detail can distract from the main findings. 

What not to do

Don’t

  • Rewrite your abstract. Statements with “we investigated” or “we studied” generally do not belong in the discussion. 
  • Include new arguments or evidence not previously discussed. Necessary information and evidence should be introduced in the main body of the paper. 
  • Apologize. Even if your research contains significant limitations, don’t undermine your authority by including statements that doubt your methodology or execution. 
  • Shy away from speaking on limitations or negative results. Including limitations and negative results will give readers a complete understanding of the presented research. Potential limitations include sources of potential bias, threats to internal or external validity, barriers to implementing an intervention and other issues inherent to the study design. 
  • Overstate the importance of your findings. Making grand statements about how a study will fully resolve large questions can lead readers to doubt the success of the research.

Ultra-precise ‘nuclear’ clock in sight

Researchers have used a laser to prompt tiny energy shifts in an atomic nucleus — a major step towards building nuclear clocks. These could be around 10 times more accurate than the world’s current best timekeepers, known as optical clocks, and less sensitive to disturbances. “We will be able to probe scenarios of dark matter and of fundamental physics that are currently inaccessible to other methods,” says theoretical physicist Elina Fuchs. To turn the system into an actual clock, physicists will need to build higher-resolution lasers that nudge the nucleus with more precision.

Hot super-Earth has atmosphere

Investigations using the James Webb Space Telescope have confirmed that the exoplanet 55 Cancri e has a carbon-based atmosphere — the first time an atmosphere has been detected surrounding a rocky planet similar to Earth outside the Solar System. The planet orbits very close to its Sun-like star and can’t support life as we know it, in part because it is probably covered by a magma ocean. “Earth probably went through at least one magma-ocean stage, maybe several,” says planetary geologist Laura Schaefer. “Having actual present-day examples of magma oceans can help us understand the early history of our Solar System.”

Brazilian universities hit by strikes

Academic workers at some Brazilian institutions are entering their fourth week of strikes for better wages and more university funding . They say the country’s president has come up short in his promise to boost science and education funding, in part because of opposition from legislators. “We are not against the government,” says botanist Thiago André. “We are in negotiation with the government.” The strikes have halted classes on many campuses, although many scientists are continuing their research. It’s unclear when the strike will end.

“If you’re passionate about research, about science, I think my advice is to never give up,'' says Syrian biochemist Aref Kyyaly. He recalls being close to abandoning his work when, in 2013, he decided to flee war-torn Aleppo with his family . The Council for At-Risk Academics helped Kyyaly secure a visa and job in the United Kingdom. “It was like a door was opened for me.” Kyyaly has been granted permission to stay in the country and has secured a permanent job as a biomedical science lecturer, but his immigration status has hindered his career: “I have friends who started four or five years after me and now they’re way ahead of me.”

‘Nanopore’ sequencing: now for proteins

By squeezing a protein through a nanopore — a tiny opening created by another protein — researchers are starting to decipher the string of amino acid building blocks that proteins are made of . This nanopore sequencing is mostly used for DNA whose building blocks can be ‘read out’ as it passes through the nanopore, driven by an electrical current. Proteins can’t be moved consistently by a current, so researchers have found ways to push or pull them through a pore using water, enzymes or molecular motors. “All the pieces are there to start with to do single-molecule proteomics and identify proteins and their modifications using nanopores,” says chemical biologist Giovanni Maglia.

How to illuminate the ‘ugly’ side of science

Data repositories, workshops and alternative journals allow scientists to share and discuss negative results, which could help to solve the reproducibility crisis and give machine learning a boost . Publishing negative results is often seen as not worth the time and effort, yet “understanding the reasons for null results can really test and expand our theoretical understanding”, says psychologist Wendy Ross. And highlighting negative results can help students to see that “you are not a bad researcher because you fail”, adds computer scientist Ella Peltonen.

A newly formed crater of Italy’s Etna volcano puffs out perfect 'smoke rings' . These volcanic vortex rings form when cold air above the volcano causes hot gases travelling up the walls of a round vent to condense. Such displays are rare: the vent must have a circular shape and sides of the same height for such well-defined rings to form.

Climate Change Added a Month’s Worth of Extra-Hot Days in Past Year

Since last May, the average person experienced 26 more days of abnormal warmth than they would have without global warming, a new analysis found.

By Raymond Zhong

Over the past year of record-shattering warmth, the average person on Earth experienced 26 more days of abnormally high temperatures than they otherwise would have, were it not for human-induced climate change, scientists said Tuesday.

The past 12 months have been the planet’s hottest ever measured, and the burning of fossil fuels, which has added huge amounts of heat-trapping gases to the atmosphere, is a major reason. Nearly 80 percent of the world’s population experienced at least 31 days of atypical warmth since last May as a result of human-caused warming, the researchers’ analysis found.

Hypothetically, had we not heated the globe to its current state , the number of unusually warm days would have been far fewer, the scientists estimated, using mathematical modeling of the global climate.

The precise difference varies place to place. In some countries, it is just two or three weeks, the researchers found. In others, including Colombia, Indonesia and Rwanda, the difference is upward of 120 days.

“That’s a lot of toll that we’ve imposed on people,” said one of the researchers who conducted the new analysis, Andrew Pershing, the vice president for science at Climate Central, a nonprofit research and news organization based in Princeton, N.J., adding, “It’s a lot of toll that we’ve imposed on nature.” In parts of South America and Africa, he said, it amounts to “120 days that just wouldn’t be there without climate change.”

Currently, the world’s climate is shifting toward the La Niña phase of the cyclical pattern known as the El Niño-Southern Oscillation. This typically portends cooler temperatures on average. Even so, the recent heat could have reverberating effects on weather and storms in some places for months to come. Forecasters expect this year’s Atlantic hurricane season to be extraordinarily active, in part because the ocean waters where storms form have been off-the-charts warm.

The analysis issued Tuesday was a collaboration between several groups: Climate Central, the Red Cross Red Crescent Climate Centre and World Weather Attribution, a scientific initiative that examines extreme weather episodes. The report’s authors considered a given day’s temperature to be abnormally high in a particular location if it exceeded 90 percent of the daily temperatures recorded there between 1991 and 2020.

The average American experienced 39 days of such temperatures as a result of climate change since last May, the report found. That’s 19 more days than in a hypothetical world without human-caused warming. In some states, including Arizona and New Mexico in the Southwest and Washington and Oregon in the Northwest, the difference is 30 days or more, a full extra month.

The scientists also tallied up how many extreme heat waves the planet had experienced since last May. They defined these as episodes of unseasonable warmth across a large area, lasting three or more days, with significant loss of life or disruption to infrastructure and industry.

In total, the researchers identified 76 such episodes over the past year, affecting 90 countries, on every continent except Antarctica. There was the punishing hot spell in India last spring. There was the extreme heat that worsened wildfires and strained power grids in North America, Europe and East Asia last summer. And, already this year, there has been excessive warmth from Africa to the Middle East to Southeast Asia .

The Ethical and Practical Drawbacks of Animal Testing

This essay is about the ethical and practical drawbacks of animal testing. It discusses the suffering inflicted on animals during experiments, raising serious moral concerns, especially with the availability of alternative methods. The essay questions the scientific validity of animal testing, noting that biological differences between animals and humans can lead to inaccurate results. It highlights advancements in technology, such as in vitro testing and organ-on-a-chip, which offer more humane and effective alternatives. Economic considerations and public opposition to animal testing are also examined, alongside the impact of consumer demand for cruelty-free products. The essay concludes that prioritizing humane research methods is both a moral and scientific necessity.

How it works

Animal experimentation has remained a contentious subject, evoking substantial moral, scientific, and pragmatic considerations. Despite its historical contributions to medical and scientific progress, the deficiencies inherent in employing animals for investigative purposes are significant and warrant careful scrutiny. The ethical quandaries, compounded by uncertainties regarding the reliability and indispensability of such assessments, necessitate meticulous evaluation.

Foremost among the concerns surrounding animal testing is the ethical conundrum it engenders. Numerous experiments entail procedures that inflict anguish, torment, and enduring detriment upon animals.

This raises profound ethical dilemmas regarding the justification of such practices, particularly in the presence of viable alternatives. The ethos of minimizing harm occupies a central position in ethical scientific inquiry, yet animal experimentation frequently runs counter to this ethos. Creatures subjected to research, such as rodents, lagomorphs, and primates, endure conditions and interventions that precipitate considerable physical and psychological anguish. Their captivity in constrained confines, deprivation of natural behaviors, and exposure to intrusive procedures exacerbate their plight, exacerbated by their incapacity to provide consent, rendering their utilization inherently exploitative.

Furthermore, the scientific validity of animal-based experiments is increasingly being scrutinized. Animals exhibit biological disparities from humans, potentially yielding results that are either inaccurate or inapplicable. Pharmaceuticals and therapies that demonstrate efficacy in animal models often falter in human clinical trials, underscoring the limitations of such modalities. Despite extensive testing in animal subjects, a significant proportion of prospective medications flounder during human clinical trials due to unforeseen side effects or ineffectiveness. This not only impugns the reliability of animal experimentation but also implies that resources could be more judiciously allocated to the development and deployment of alternative methodologies, likely yielding data that is more germane to human health outcomes.

Technological advancements have yielded viable substitutes for animal testing that are both humane and scientifically rigorous. In vitro assays, computational modeling, and human-derived tissue methodologies frequently obviate the necessity for animal models. These alternatives proffer more precise prognostications of human reactions to drugs and other substances, curtailing the risk of clinical trial setbacks. For instance, microfluidic organ-on-a-chip platforms employ human cellular substrates to simulate physiological responses, affording a more pertinent context for experimentation than animal counterparts. Such approaches not only assuage ethical misgivings but also harbor the potential to enhance the efficiency and efficacy of scientific inquiry.

The economic dimension of animal experimentation constitutes another salient consideration. The upkeep of animal facilities and execution of experiments entail considerable expenditure. The fiscal onus of these practices can be formidable, diverting resources from potentially more efficacious and ethical investigative methodologies. Investments in alternative testing modalities often prove more financially prudent in the long term, necessitating fewer resources and facilitating scalability relative to animal-based paradigms. Furthermore, diminishing reliance on animal experimentation accords with public sentiment and consumer demand for products untainted by cruelty, thereby burnishing the reputations and marketability of enterprises embracing more humane methodologies.

Public sentiment has increasingly turned against animal experimentation, propelled by burgeoning awareness of animal rights and the availability of alternative testing methodologies. Many individuals are disinclined to patronize products and endorse research entailing animal suffering, prompting intensified pressure on corporations and institutions to espouse ethical practices. Legislative initiatives in diverse jurisdictions have likewise mirrored this perceptual shift, culminating in the enactment of statutes and regulations curbing or proscribing animal experimentation, particularly concerning cosmetics and household products. This legal and societal transformation underscores the imperative for the scientific community to explore and invest in alternative modalities.

In addition to ethical, scientific, and economic considerations, the matter of species-specific responses merits attention. Animals frequently manifest divergent reactions to substances vis-à-vis humans, confounding the interpretation of experimental outcomes. For instance, a substance toxic to a rodent may prove innocuous to a human, and vice versa. This variability introduces an additional stratum of complexity to the elucidation of animal testing results, further impugning the utility of such approaches. Emphasizing alternative methodologies predicated on human-centric data can ameliorate these challenges and yield outcomes that are more precise and dependable.

Moreover, there exists the contention that the conditions prevailing in laboratory settings do not faithfully replicate the real-life circumstances to which humans are exposed, thereby impinging upon the validity of findings. Animals inhabiting laboratories contend with perpetual stressors that can engender physiological and psychological perturbations, potentially skewing experimental results. This regimented milieu diverges starkly from the intricate and variegated environments humans inhabit, casting doubt upon the applicability of findings derived from animal testing to human contexts.

Furthermore, the ascendancy of ethical consumerism has precipitated heightened scrutiny of corporate practices. Consumers are increasingly discerning and conscientious concerning the provenance and production methods of commodities. Enterprises persisting in animal experimentation confront censure and boycotts, with deleterious ramifications for their financial viability. Conversely, those embracing cruelty-free practices often enjoy augmented patronage and loyalty from an expanding demographic that esteems ethical production. This consumer-driven metamorphosis is impelling industries to innovate and devise alternatives to animal experimentation.

Additionally, animal experimentation portends a pronounced risk of exacerbating environmental imbalances. A plethora of animals earmarked for research are bred explicitly for this purpose, prompting inquiries into biodiversity and the ecological ramifications of sustaining these populations. The breeding and utilization of myriad animals annually for testing purposes engender far-reaching repercussions transcending immediate ethical and scientific apprehensions.

As we advance in genetics, biotechnology, and computational sciences, the rationale for animal experimentation becomes increasingly tenuous. Technologies such as CRISPR gene editing, 3D bioprinting, and sophisticated computer simulations furnish potent tools for researchers capable of replicating human physiological processes with greater fidelity than animal models. These innovations hold the promise of bridging the lacuna between preclinical investigations and human trials, potentially expediting the development of novel therapeutics and attenuating dependence on animal testing.

In summation, while animal experimentation has historically underwritten scientific and medical progress, its ethical and practical limitations warrant acknowledgment. The suffering inflicted upon animals, the dubious reliability of animal models, and the availability of alternative methodologies militate against sustained reliance on animal experimentation. As technology burgeons and public sentiments evolve, it is incumbent upon the scientific community to accord primacy to humane and efficacious research modalities. By doing so, we can uphold ethical benchmarks, enhance scientific precision, and foster a more compassionate approach to inquiry. The transition toward alternative testing methodologies is not merely a moral imperative but also a scientific exigency, ensuring that forthcoming research is both ethical and efficacious.
