How to Do a Science Investigatory Project

Last Updated: February 2, 2024 Fact Checked

This article was co-authored by Bess Ruff, MA . Bess Ruff is a Geography PhD student at Florida State University. She received her MA in Environmental Science and Management from the University of California, Santa Barbara in 2016. She has conducted survey work for marine spatial planning projects in the Caribbean and provided research support as a graduate fellow for the Sustainable Fisheries Group.

A Science Investigatory Project (SIP) uses the scientific method to study and test an idea about how something works. It involves researching a topic, formulating a working theory (or hypothesis) that can be tested, conducting the experiment, and recording and reporting the results. You will probably need to follow this procedure if you are planning to enter a project in a school science fair, for instance. However, knowing how to do an SIP is useful for anyone interested in the sciences as well as anyone who wants to improve their problem-solving skills.

Employing the Scientific Method

Step 1 Ask a question.

  • Think about something that interests, surprises, or confuses you, and consider whether it is something you can reasonably investigate for a project. Formulate a single question that sums up you would like to examine. [1] X Research source
  • For instance, say you've heard that you can make a simple solar oven out of a pizza box. [2] X Research source You may, however, be skeptical as to whether this can be done, or done consistently at least. Therefore, your question might be: "Can a simple solar oven be made that works consistently in various conditions?"
  • Make sure the topic you select is manageable within your time frame, budget, and skill level, and that it doesn't break any rules for the assignment/fair/competition (for example, no animal testing). You can search for ideas online if you need help, but don't just copy a project you find there; this will also be against the rules and is unethical.
  • However, you can modify an existing project to test a different hypothesis or look into a question that was not answered by previous experiments. This isn't an ethical breach, and can often make for interesting results and discussions.

Step 2 Research your topic.

  • Be aware of the requirements for your project. Many science fairs require that you have at least three reputable academic sources such as peer-reviewed journal publications to use as references. [4] X Research source
  • Your sources will need to be unbiased (not tied to a product for sale, for instance), timely (not an encyclopedia from 1965), and credible (not some anonymous comment on a blog post). Web sources that are supported by a scientific organization or journal are a good bet. Ask your teacher or project director for guidance if you need it.
  • For instance, the search query "how to make a solar oven out of a pizza box" will produce a bounty of sources, some more scientifically-grounded (and thus reliable) than others. The hit on an on-topic article in a recognized, reputable periodical should be considered a valid source. [5] X Research source
  • On the other hand, blog posts, anonymous articles, and crowd-sourced materials probably won't make the cut. As valuable a resource as wikiHow is, it may not be considered a valid source for your SIP. It can, however, be helpful in introducing you to your chosen experiment and pointing you toward more academic sources. Choosing well-developed articles with numerous footnotes (that link to solid sources themselves) will improve the odds of acceptance, but discuss the issue with your instructor, fair organizer, etc.

Step 3 Form a hypothesis...

  • It is often helpful to turn your question into a hypothesis by thinking in "if / then" terms. You may want to frame your hypothesis (at least initially) as "If [I do this], then [this will happen]."
  • For our example, the hypothesis might be: "A solar oven made from a pizza box can consistently heat foods any time there is abundant sunshine."

Step 4 Design your experiment.

  • Consideration of variables is key in setting up your experiment. Scientific experiments have three types of variables: independent (those changed by you); dependent (those that change in response to the independent variable); and controlled (those that remain the same). [8] X Trustworthy Source Science Buddies Expert-sourced database of science projects, explanations, and educational material Go to source
  • When planning your experiment, consider the materials that you will need. Make sure they are readily available and affordable, or even better, use materials that are already in your house.
  • For our pizza box solar oven, the materials are easy to acquire and assemble. The oven, item cooked (s'mores, for instance), and full sunshine will be controlled variables. Other environmental conditions (time or day or time of year, for instance) could be the independent variable; and "done-ness" of the item the dependent variable.

Step 5 Conduct your experiment.

  • Closely follow the steps that you have planned to test your experiment. However, if your test can not be conducted as planned, reconfigure your steps or try different materials. (If you really want to win the science fair, this will be a big step for you!)
  • It is common practice for science fairs that you will need to conduct your test at least three times to ensure a scientifically-valid result. [10] X Trustworthy Source Science Buddies Expert-sourced database of science projects, explanations, and educational material Go to source
  • For our pizza box oven, then, let's say you decide to test your solar oven by placing it in direct sun on three similar, 90-degree Fahrenheit days in July, at three times each day (10 am, 2 pm, 6 pm).

Step 6 Record and analyze your results.

  • Sometimes your data may be best recorded as a graph, chart, or just a journal entry. However you record the data, make sure it is easy to review and analyze. Keep accurate records of all your results, even if they don't turn out the way you hoped or planned. This is also part of science! [11] X Research source
  • As per the solar oven tests at 10 am, 2 pm, and 6 pm on three sunny days, you will need to utilize your results. By recording the done-ness of your s'mores (by how melted the chocolate and marshmallow is, for instance), you may find that only the 2 pm placement was consistently successful. [12] X Research source

Step 7 Make your conclusion.

  • If you started out with a simple, clear, straightforward question, and a similar hypothesis, it should be easier to craft your conclusion.
  • Remember, concluding that your hypothesis was completely wrong does not make your SIP a failure. If you make clear, scientifically-grounded findings, and present them well, it can and will be a success.
  • In the pizza box solar oven example, our hypothesis was "A solar oven made from a pizza box can consistently heat foods any time there is abundant sunshine." Our conclusion, however, might be: "A solar oven made from a pizza box can only be consistently successful in heating foods in mid-day sun on a hot day."

Explaining and Presenting Your Project

Step 1 Know how your project will be evaluated.

  • For a science fair, for example, the judging could be based on the following criteria (adding up to 100%): research paper (50%); oral presentation (30%); display poster (20%).

Step 2 Create an abstract.

  • SIP abstracts are often limited to one page in length, and perhaps 250 words. In this short space, focus on the purpose of your experiment, procedures, results, and any possible applications. [14] X Research source

Step 3 Write a research paper

  • Use the guidelines provide by your teacher or the science fair director for information on how to construct your research paper.
  • As one example, your paper may need to be broken down into categories such as: 1) Title Page; 2) Introduction (where you identify your topic and hypothesis); 3) Materials & Methods (where you describe your experiment); 4) Results & Discoveries (where you identify your findings); 5) Conclusion & Recommendations (where you "answer" your hypothesis); 6) References (where you list your sources).

Step 4 Prepare your oral presentation.

  • Write up your research paper first, and use it as your guide in constructing your oral presentation. Follow a similar framework in outlining your hypothesis, experiments, results, and conclusions.
  • Focus on clarity and concision. Make sure everyone understands what you did, why you did it, and what you discovered in doing it.

Step 5 Make a visual aid.

  • Science fairs commonly use a standard size, three panel display board, approximately 36 inches high by 48 inches wide.
  • You should lay out your poster like the front page of a newspaper, with your title at the top, hypothesis and conclusion front and center, and supporting materials (methods, sources, etc.) clearly placed under headings on either side.
  • Use images, diagrams, and the like to spruce up the visual appeal of your poster, but don't sacrifice content for visual pizzazz.

About This Article

Bess Ruff, MA

To do a science investigatory project, start by thinking about a question you'd like to answer. For example, you may be wondering “Does the same kind of mold grow on different types of bread?” Then, once you have a question that's specific, form a hypothesis about what you think the answer will be. For this experiment, a good hypothesis might be “While all bread will produce the same kind of mold, the type of bread will impact how fast the mold grows.” With this hypothesis in mind, grab a few different kinds of of bread, set up your work station, and do your experiment at least 3 times to make sure the results are right.

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.

Hypothesis Examples

Hypothesis Examples

A hypothesis is a prediction of the outcome of a test. It forms the basis for designing an experiment in the scientific method . A good hypothesis is testable, meaning it makes a prediction you can check with observation or experimentation. Here are different hypothesis examples.

Null Hypothesis Examples

The null hypothesis (H 0 ) is also known as the zero-difference or no-difference hypothesis. It predicts that changing one variable ( independent variable ) will have no effect on the variable being measured ( dependent variable ). Here are null hypothesis examples:

  • Plant growth is unaffected by temperature.
  • If you increase temperature, then solubility of salt will increase.
  • Incidence of skin cancer is unrelated to ultraviolet light exposure.
  • All brands of light bulb last equally long.
  • Cats have no preference for the color of cat food.
  • All daisies have the same number of petals.

Sometimes the null hypothesis shows there is a suspected correlation between two variables. For example, if you think plant growth is affected by temperature, you state the null hypothesis: “Plant growth is not affected by temperature.” Why do you do this, rather than say “If you change temperature, plant growth will be affected”? The answer is because it’s easier applying a statistical test that shows, with a high level of confidence, a null hypothesis is correct or incorrect.

Research Hypothesis Examples

A research hypothesis (H 1 ) is a type of hypothesis used to design an experiment. This type of hypothesis is often written as an if-then statement because it’s easy identifying the independent and dependent variables and seeing how one affects the other. If-then statements explore cause and effect. In other cases, the hypothesis shows a correlation between two variables. Here are some research hypothesis examples:

  • If you leave the lights on, then it takes longer for people to fall asleep.
  • If you refrigerate apples, they last longer before going bad.
  • If you keep the curtains closed, then you need less electricity to heat or cool the house (the electric bill is lower).
  • If you leave a bucket of water uncovered, then it evaporates more quickly.
  • Goldfish lose their color if they are not exposed to light.
  • Workers who take vacations are more productive than those who never take time off.

Is It Okay to Disprove a Hypothesis?

Yes! You may even choose to write your hypothesis in such a way that it can be disproved because it’s easier to prove a statement is wrong than to prove it is right. In other cases, if your prediction is incorrect, that doesn’t mean the science is bad. Revising a hypothesis is common. It demonstrates you learned something you did not know before you conducted the experiment.

What is a Science Investigatory Project?

Dr Harry Hothi

  • By Dr Harry Hothi
  • August 27, 2020

Science Investigatory Project

Many of the STEM (science, technology, engineering and mathematics) PhD students that we’ve interviewed on our site have also been active STEM ambassadors. This means that they engage with school children to help them learn more about scientific research and become enthused with STEM subjects. This can be in the form of giving talks at schools, producing online videos and also becoming involved as mentors in science investigatory projects. This page gives you more detail about the latter.

A science investigatory project (SIP) refers to a science-based research project or study that is performed by school children. An SIP is usually a science experiment performed in a classroom setting with the class separated into small groups, but can also form part of a scientific exhibition or fair project.

The main aim of a science investigatory project is for it to provide school aged children with an engaging way to learn more about science and the concept of performing scientific research. The approaches used are often broadly aligned with those used by PhD students carrying out a research project. The hope here is that it sparks an interest in the children about scientific concepts or STEM subjects in general and that this interest is carried forward to the university level.

These are intended to be a fun way to learn about the scientific process and research. If you as PhD student have the opportunity to become involved in an SIP, then definitely take it up! If you do, then approach the exercise with the aim of teaching the school children about the following 6 research concepts:

  • Defining a Research Question . This could happen after a classroom lesson introducing the children to a new concept. Depending on their age, encourage them to spend time reading up about the subject independently (i.e. a first review of literature using Google searches). Guide them in coming up with a research question that they genuinely don’t know the answer to yet. Can they find out what a dependent variable is and an independent variable? Also help them understand what constitutes a controlled experiment. A popular investigatory project is one based around finding out if used cooking oil can be purified using a sedimentation method so that it can be recycled.
  • Formulating a Null Hypothesis . Help the children understand the concept of the hypothesis and null hypothesis and refine the research question into this format. The null hypothesis for the above example could be ‘sedimentation is not able to purify used cooking oil’.
  • Agreeing a Study Design . Come up with the scientific method needed to test the hypothesis and run the experiments to collect data.
  • Collecting and Interpreting Results . Encourage the children to discuss the results they find and what they could mean. Using our example, can they see any differences between unused oil and oil that they tried to purify? Did the process work?
  • Concluding the Study . Have them think about their results and what their original null hypothesis was. Do they think the null hypothesis is true – i.e. did they show that sedimentation was not able to purify used cooking oil?
  • Presenting the Work . This should be a fun way to learn about the important skill of presenting your research. This might be in the form of a written page describing what they did and what they found and including a summary graph of results. Another good approach is to encourage them to give short presentations using photos of their experimental setup.

Science Investigatory Project STEM

Getting involved in a science investigatory project can be a great outreach activity to promote STEM subjects and scientific research to children. Running a science experiment with them and teaching them to think about the scientific method used can be a lot of fun too. I definitely recommend trying it even just once during your time as a PhD student.

Concept Paper

A concept paper is a short document written by a researcher before starting their research project, explaining what the study is about, why it is needed and the methods that will be used.

Step 3: State your hypothesis

Now it's time to state your hypothesis . The hypothesis is an educated guess as to what will happen during your experiment. 

The hypothesis is often written using the words "IF" and "THEN." For example, " If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables . 

The hypothesis should relate back to your original question and must be testable .

A word about variables...

Your experiment will include variables to measure and to explain any cause and effect. Below you will find some useful links describing the different types of variables.

Yale Shield

Science & Quantitative Reasoning Education

Yale undergraduate research, how to write a proposal.

The abstract should summarize your proposal. Include one sentence to introduce the problem you are investigating, why this problem is significant, the hypothesis to be tested, a brief summary of experiments that you wish to conduct and a single concluding sentence. (250 word limit)

Introduction

The introduction discusses the background and significance of the problem you are investigating. Lead the reader from the general to the specific. For example, if you want to write about the role that Brca1 mutations play in breast cancer pathogenesis, talk first about the significance of breast cancer as a disease in the US/world population, then about familial breast cancer as a small subset of breast cancers in general, then about discovery of Brca1 mutations in familial breast cancer, then Brca1’s normal functions in DNA repair, then about how Brca1 mutations result in damaged DNA and onset of familial breast cancer, etc. Definitely include figures with properly labeled text boxes (designated as Figure 1, Figure 2, etc) here to better illustrate your points and help your reader wade through unfamiliar science. (3 pages max)

Formulate a hypothesis that will be tested in your grant proposal. Remember, you are doing hypothesis-driven research so there should be a hypothesis to be tested! The hypothesis should be focused, concise and flow logically from the introduction. For example, your hypothesis could be “I hypothesize that overexpressing wild type Brca1 in Brca1 null tumor cells will prevent metastatic spread in a mouse xenograph model.” Based on your hypothesis, your Specific Aims section should be geared to support it. The hypothesis is stated in one sentence in the proposal. 

Specific Aims (listed as Specific Aim 1, Specific Aim 2)

This is where you will want to work with your mentor to craft the experimental portion of your proposal. Propose two original specific aims to test your hypothesis. Don’t propose more than two aims-you will NOT have enough time to do more. In the example presented, Specific Aim 1 might be “To determine the oncogenic potential of Brca1 null cell lines expressing wild type Brca1 cDNA”. Specific aim 2 might be “To determine the metastatic potential of Brca1 null cells that express WT Brca1”. You do not have to go into extensive technical details, just enough for the reader to understand what you propose to do. The best aims yield mechanistic insights-that is, experiments proposed address some mechanisms of biology. A less desirable aim proposes correlative experiments that does not address mechanistically how BRCA1 mutations generate cancer. It is also very important that the two aims are related but NOT interdependent. What this means is that if Aim 1 doesn’t work, Aim 2 is not automatically dead. For example, say you propose in Aim 1 to generate a BRCA1 knockout mouse model, and in Aim 2 you will take tissues from this mouse to do experiments. If knocking out BRCA1 results in early embryonic death, you will never get a mouse that yields tissues for Aim 2. You can include some of your mentor’s data here as “Preliminary data”. Remember to carefully cite all your sources. (4 pages max; 2 pages per Aim)

Potential pitfalls and alternative strategies

This is a very important part of any proposal. This is where you want to discuss the experiments you propose in Aims 1 and 2. Remember, no experiment is perfect. Are there any reasons why experiments you proposed might not work? Why? What will you do to resolve this? What are other possible strategies you might use if your experiments don’t work? If a reviewer spots these deficiencies and you don’t propose methods to correct them, your proposal will not get funded. You will want to work with your mentor to write this section. (1/2 page per Aim)

Cite all references, including unpublished data from your mentor. Last, First, (year), Title, Journal, volume, pages.

*8 page proposal limit (not including References), 1.5 spacing, 12pt Times New Roman font

What is a Science Investigatory Project?

Imagine stepping into the shoes of a scientist – asking questions, running experiments, and discovering the secrets of the world around you. That’s exactly what a Science Investigatory Project, or SIP, is all about.

At its core, a SIP is a thrilling journey of scientific exploration. It’s a project that challenges you to pick a problem, make educated guesses (that’s your hypothesis), roll up your sleeves for experiments, collect data, and connect the dots to find answers.

Here’s how it works

Step 1: the mystery.

You start with a question – something that piques your curiosity. It could be anything from “Why do plants grow towards the light?” to “What makes the sky blue?” Your SIP is your ticket to unravel these mysteries.

Step 2: The Guess

Next comes your hypothesis – a fancy word for your best guess at the answer. It’s like saying, “I think this is what’s happening, and here’s why.”

Step 3: The Detective Work

Now, it’s time for the fun part – experimenting! You set up tests, tweak variables, and observe closely. Whether you’re mixing chemicals, observing insects, or measuring temperature, you’re the scientist in charge.

Step 4: Clues and Evidence

As you experiment, you collect clues in the form of data – numbers, measurements, observations. It’s like gathering puzzle pieces.

Step 5: The “Aha!” Moment

When you analyze your data, patterns start to emerge. You connect those puzzle pieces until you have a clear picture. Does your data support your guess (hypothesis), or do you need to rethink things?

Step 6: Sharing Your Discovery

Scientists don’t keep their findings to themselves. They share them with the world. Your SIP report or presentation is your chance to do just that. You explain what you did, what you found, and why it matters.

So, why do SIPs matter? They’re not just school projects. They’re your chance to think like a scientist, ask questions like a detective, and discover like an explorer. They’re where you become the expert, the innovator, the problem-solver.

From the mysteries of biology to the wonders of chemistry and the enigmas of physics, SIPs open doors to countless adventures in science. So, what question will you ask? What mystery will you solve? Your SIP journey awaits – embrace it, and you might just uncover something amazing.

A hypothesis is an educated guess about what you think will happen in a scientific experiment, based on your observations. Before conducting the experiment, you propose a hypothesis so that you can determine if your prediction is supported.

There are several ways you can state a hypothesis, but the best hypotheses are ones you can test and easily refute. Why would you want to disprove or discard your own hypothesis? Well, it is the easiest way to demonstrate that two factors are related. Here are some good scientific hypothesis examples:

  • Hypothesis: All forks have three tines. This would be disproven if you find any fork with a different number of tines.
  • Hypothesis: There is no relationship between smoking and lung cancer. While it is difficult to establish cause and effect in health issues, you can apply statistics to data to discredit or support this hypothesis.
  • Hypothesis: Plants require liquid water to survive. This would be disproven if you find a plant that doesn't need it.
  • Hypothesis: Cats do not show a paw preference (equivalent to being right- or left-handed). You could gather data around the number of times cats bat at a toy with either paw and analyze the data to determine whether cats, on the whole, favor one paw over the other. Be careful here, because individual cats, like people, might (or might not) express a preference. A large sample size would be helpful.
  • Hypothesis: If plants are watered with a 10% detergent solution, their growth will be negatively affected. Some people prefer to state a hypothesis in an "If, then" format. An alternate hypothesis might be: Plant growth will be unaffected by water with a 10% detergent solution.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.

What's an Investigatory Project Exactly?

An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you've created your hypothesis or proposal, you can conduct a controlled experiment using the scientific method to arrive at a conclusion.

What's the Scientific Method?

For those of us who have forgotten the various steps of the scientific method, let me clear that up right here:

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome. The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail.

What Kind of Investigatory Projects Are There?

In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be.

I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea.

Project #1: Making Soap Out of Guava

Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? This is a great question that makes you think about scientific alternatives to store-bought soap.

Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen .

Project #2: Used Cooking Oil as a Substitute for Diesel

We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet? With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting.

Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project. And who knows, maybe in doing this you'll actually figure out what was missing from previous attempts . Being an instant billionaire doesn't sound too bad to me.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

If you're interested in trying it for yourself, there's a great step-by-step guide with a full ingredients list and photos over on Make .

Project #3: Create Another Alternative Fuel

If biodiesel isn't your forte, you can try making oxyhydrogen gas or creating hydrogen gas via electrolysis or vice versa, creating electricity from hydrogen gas .

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Project #4: Purifying Used Cooking Oil

Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. But what if you could clean that oil and use it over and over again? Not only would that save money, but it would also benefit the environment since most people do not properly dispose of used cooking oil (no, pouring it down the drain doesn't count).

Your project goal would be to research methods of filtration or purification and test it on cooking oils. To easily demonstrate which method works best, try cooking some food in the oil produced by each one. Good food can go a long way when it comes to winning people over.

Check out the abstract and description of a similar project here .

Project #5: Alternative Methods of Producing Iodized Salt

In areas isolated from the sea, IDD or Iodine Deficiency Disease, is very common. Since these areas do not have easy access to marine foods or grocery stores, the population becomes very susceptible to the disease due to a lack of iodine in the diet. In order to combat this, researchers and doctors have begun infusing iodine into regular table salts.

If not iodine is readily available, it can be chemically made either with sulfuric acid and alkali metal iodide or hydrochloric acid and hydroxide peroxide .

But perhaps there are other more accessible ways to create an iodized salt that people could make at home. For a starting point, take a look at this previous experiment .

Project #6: Making Biodegradable Plastic

Plastic bags are actually illegal in Santa Monica , CA (and soon to be Los Angeles ) because of their threat to the environment due to insane resistance to biodegradation. I didn't think they were that bad, but one plastic bag can take up to 1,000 years to break down completely, and it can even ruin your car along the way. So, creating a better biodegradable plastic bag would be a huge achievement.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

The only question is how one would go about doing so, and what materials could be used? That's the question you can answer for your project. This project used cassava starch as an effective component for a biodegradable plastic, but you could try using a few different starches and see what works best.

Project #7: Solar Water Purification

One of the biggest world problems is finding clean water. While we in the states can find purified or drinkable tap water almost anywhere, millions of people around the world don't have access to clean drinking water.

A few students decided to investigate a potential purification process using the sun's energy and an aluminum sheet. Watch the video below for more information and a complete walkthrough of their scientific process.

And if you're an overachiever, you can step it up a notch and try purifying pee instead .

Project #8: Perfecting the Paper Bridge

Of course, an investigatory project doesn't always have to answer such grand questions. This experiment looks to discover how to build the strongest paper bridge by varying how the pieces are held together. So, the question is, "How do design changes affect a load bearing structure?"

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Check out the video below for more information on replicating the project yourself.

Project #9: Making Instant Ice

It's summer time and the degrees are already hitting triple digits in some areas. When it's this hot, there are few things better than a glass of ice chilled water or lemonade. But what happens if you don't have ice? Can you create your own ice or cool drinks quickly by another method? Check out this clip from King of Random .

Cool, huh? But how does it work? Is there any other way to replicate this? Well, let the investigation begin. Figure out what your hypotheses will be and follow along with this video for you own investigatory project.

For more information and additional photos, be sure to check out the King of Random's full tutorial .

Project #10: Increase the Shelf-Life of Fruits and Veggies

Extending the shelf-life of perishable fruits and vegetables can make a huge difference for small farmers, street-side vendors and even your average Joe—groceries aren't cheap. What is an inexpensive and easily accessible way to make produce stay fresh longer?

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

That's the question behind this great investigatory science project featured here . While these researchers focused exclusively on chitosan coating on bananas, you can branch out (no pun intended) and try an assortment of other fruits, veggies and possible coating materials.

For more information on how to keep your fruits and vegetables fresh for longer, check out my previous article , or Yumi's recent illustration for other ideas.

Project #11: Slow the Ripening of Sliced or Chopped Produce

You could also focus your project on keeping fruits and vegetables from browning after they've already been cut up. There are various methods and materials you can use to slow down the ripening process, such as honey and lemon juice. Watch the video below and read this tutorial for more information and ideas.

Your project could revolve around finding the best option, and testing out some of your own browning-prevention solutions to see if you can come up with a better one.

Project #12: Improve Memory by Thinking Dirty

If my memory was any good I would be fluent in Spanish and never need to look up the Quadratic Formula again. But my problems are more superficial, like forgetting where I put my keys or what time my dentist appointment was supposed to be. There are folks out there who do suffer from real memory problems, so figuring out how to help improve memory makes for a great investigatory project.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

There are tons of studies on memory and memory loss that you can research. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out. Does using colors to form associations help with memory? Does linking an image with a memory increase its hold in the carrier's head? What about drinking grape juice or sniffing rosemary ? These are the types of questions you may look to answer.

This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. Come up with your own theory and let the brain hacking begin.

Project #13: Improving Social Anxiety by Manipulating the Body & Mind

Science experiments don't always have to include chemicals or test tubes. The science of the mind can be just as interesting. So what's the investigation consist of?

Can you truly affect the way you act and feel by simply changing your posture? Does acting a certain way manipulate the mind drastically enough to actually change the way you feel?

Check out Amy Cuddy's awesome TED Talk for more ideas for additional questions you could ask.

Project #14: Kitchen DNA Extraction

You may think studying DNA is only for professionals with super expensive lab equipment, but you can actually extract DNA from any living thing with a few basic ingredients you probably have in your kitchen like dish soap and rubbing alcohol.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Decide on something to vary, like different fruits and vegetables or types of dish soap, and come up with a hypothesis regarding which will allow you to collect the most DNA material.

You can also find more information, as well as another way to perform the experiment, here .

Project #15: Make Homemade Glue from Milk

With milk, white vinegar and baking soda, you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster, or work on different materials (wood vs. plastic vs. paper).

Fish swimming together fare better in turbulent waters

By Laura Baisas

Posted on Jun 6, 2024 2:00 PM EDT

3 minute read

Deposit Photos

Schooling fish including zebrafish , rainbowfish, and opahs/moonfish like to stick together in the big blue. Scientists believe that traveling in schools has numerous evolutionary benefits , but it also could be more beneficial to their general movements . They also may have an easier time swimming through the ocean’s more turbulent waters than those that go it alone. The findings are described in a study published June 6 in the open-access journal PLOS Biology .

Do the locomotion

Locomotion –the way animals move from one place to another–is critical to several aspects of their behavior. Various movements are needed during their migration periods , reproduction, and when feeding. Many species have different adaptations to make moving around more efficient to compensate. Fish have sleek and streamlined bodies that create little resistance in the water, scales that allow for flexible movements and physical protection, and gills that extract oxygen.

“Generating movement through the environment is one of the defining features of animals. Yet the environment can be very challenging with obstacles and animals often face difficult conditions that increase the cost of movement,” study co-authors and evolutionary biologists Yangfan Zhang and George Lauder of Harvard University, tell Popular Science .

[Related: Why do we send so many fish to space? ]

Scientists in different fields have proposed several hypotheses for why the collective movements of animals are beneficial. It could enhance mating success, help them avoid predators, or make it easier for animals to communicate when finding food. 

In this study , the team proposes a new hypothesis for navigating more challenging waters. Their turbulent sheltering hypothesis suggests that traveling in schools allows fish to shield each other from more disruptive water currents. 

“The turbulence sheltering hypothesis has not been previously proposed so this study is the first to both propose and test it,” says Zhang. “For many years now, there have not been any substantially new ideas on why fish in particular might school and move as a collective group.  The turbulence sheltering hypothesis provides a new idea for why fishes might gain an energetic advantage by moving as a school.”

Testing the turbulence sheltering hypothesis

To put this hypothesis to the test, the team ran trials with giant danios ( Devario aeqipinnatus ). These types of carp regularly swim in schools and are only about one to two inches long, despite the superlative in their name. The team observed the danios swimming alone or in groups of eight in both turbulent and more steadily flowing water. High-speed cameras captured the animals’ movements as they swam and the team simultaneously measured the fishes’ respiration rate and energy expenditure.

[Related: Making babies may take 10 times more energy than we thought .]

They found that the schooling fish spent up to 79 percent less energy when swimming in turbulent water compared to swimming alone. Schooling fish also clustered more closely together in the turbulent water compared to the more steady streams. Solitary fish had to beat their tails more vigorously to keep their same speed in more turbulent currents.

This activity is somewhat similar to competitive cyclists drafting off of one another during a triathlon to reduce drag. 

“A significant difference between humans in a triathlon, or cyclists moving behind each other and benefiting from the reduced flow (called a drag wake) is that fish are accelerating the flow behind them,” says Zhang. “Previous research has shown that fish can even benefit from thrust wake (an increased fluid velocity). Fish move a bit more elegantly through the fluid than humans.”

‘Dramatic benefits’

The results add some support to the turbulence sheltering hypothesis, indicating that locomotion efficiency might be a driving factor behind whey schooling behavior evolved. 

“The most surprising part of the study is the dramatic benefits that moving in a group confers when fish swim in turbulence,” says Zhang. “It’s much, much, better to swim in a school if the environmental flows are turbulent and challenging than it is to swim as a solitary individual.  In future experiments, the team plans to conduct experiments to understand what specific mechanisms enable energy saving in individual animals when they move within a group. This data is valuable in general for understanding fish ecology and the fundamentals of hydrodynamics . It could also potentially be applied to the design and maintenance of habitats that are meant to harbor protected fish species or to hinder more invasive ones.
