Solving problems in Smart Technology

Consider the hottest topic in industry today – Smart Manufacturing, or Industry 4.0, sometimes called the Industrial Internet of Things (IIOT). Industry 4.0 is just one facet of the global push towards Smart Cities, Smart Homes, and Smart Agriculture.

All these concepts center on wireless connectivity between machines using cellular networks. So, for Smart Homes, this means your utilities, fridge, lights, security, HVAC, and other systems would be connected through an app on your smartphone. From there you can track and control these systems to keep your home safe and comfortable, while reducing water and energy use.

For Industry 4.0, companies are connecting the machines used in their manufacturing and power generation plants at different locations around the world. On top of that, they are creating “digital twins” of each machine, which are 3D animated computer models of the machines.

The idea is to collect real-time data from each machine and then use that data, along with artificial intelligence (AI), machine vision, and even virtual reality simulations, to:

• Design new products
• Predict when a machine will need maintenance BEFORE something goes wrong
• Optimize the output of the machines and harmonize them to work together

Solving problems in Robotics

Another major topic in industry is  robotics and automation . Automation means that machines are programmed to perform tasks without human help. Some robots are standalone, “service” robots, like the Roomba. Others, like robotic arms in factories and warehouses, pick and place items to be processed.

The more human-friendly “collaborative” robots can improve human capacity and are safe to work around. Put together, these technologies allow some manufacturing plants to run “lights out,” without any human input for days.

Robots are boosting agriculture, both in planting and harvesting fields and in packaging food. With Smart Agriculture technology, farmers collect data in their fields with mobile apps applying artificial intelligence (AI) software to reduce fertilizer needs and optimize water use.

STEM learning is largely about designing creative solutions for real-world problems. When students learn within the context of authentic, problem-based STEM design, they can more clearly see the genuine impact of their learning. That kind of authenticity builds engagement, taking students from groans of “When will I ever use this?” to a genuine connection between skills and application.

Using STEM to promote critical thinking and innovation

“Educational outcomes in traditional settings focus on how many answers a student knows. We want students to learn how to develop a critical stance with their work: inquiring, editing, thinking flexibly, and learning from another person’s perspective,” says Arthur L. Costa in his book Learning and Leading with Habits of Mind . “The critical attribute of intelligent human beings is not only having information but also knowing how to act on it.”

Invention and problem-solving aren’t just for laboratory thinkers hunkered down away from the classroom. Students from elementary to high school can wonder, design, and invent a real product that solves real problems. “ Problem-solving involves finding answers to questions and solutions for undesired effects. STEM lessons revolve around the engineering design process (EDP) — an organized, open-ended approach to investigation that promotes creativity, invention, and prototype design, along with testing and analysis,” says Ann Jolly in her book STEM by Design . “These iterative steps will involve your students in asking critical questions about the problem, and guide them through creating and testing actual prototypes to solve that problem.”

E-I-E-I-Annoying Grunt (Season 11, Episode 5)

Final example:  Less of a “traditional” project, but as the Simpsons are hiding out on a farm, Homer decides to try planting crops.  When Marge suggests fertilizer, Homer borrows plutonium from the power plant.  The result – a new hybrid tomato is born!

CONCLUSION:  It’s not whether you win or lose…  it’s how you do your science!

I’ll never forget my younger daughter’s second science fair experience.  She and her partner did a great job brainstorming ideas.  Then, the enthusiasm waned a bit.  Then, it came back!  After ~3 weekends the final project came together.  Overall, the parents really stood back and let them run with things.

While I helped construct a demo volcano, the board was entirely done by them (3rd grader style complete with Christmas lights!).  You might imagine that it might not have been as sharp in quality as others that had more parental assistance.  🙂

You know what?  It didn’t matter…

At the presentation, they knew their stuff!

They clearly communicated their hypothesis, their experimental design, results and conclusions.

Then…

THEY BLEW UP A VOLCANO!!  WOOHOO!!

When they came back to find a 1st place ribbon, the smiles were ear to ear!  Tons of shrieks and giggles!  Winning science fair projects don’t always start that way.  In the end, what’s most important — have a positive experience.

If you’ve won a science fair competition, share your project in the comments and what your winning strategy involved!  Or, if you’re struggling to narrow it down, share some ideas.

15 Cool Science Fair Projects

Hoping to enter a science fair for kids but not sure where to begin? The purpose of science fair projects are about more than simply coming up with a cool idea and sharing it with others.

Aside from the competitive glory of competing (and maybe winning) at a science fair, kids gain experience working with the scientific method: asking questions, forming hypotheses, testing, collecting data, and sharing results with others. Aside from these fundamental STEM skills, kids also gain valuable experience in collaboration, organizational skills, problem solving, communication, and creativity, turning that cool science fair project into a stepping stone on the path towards a career in science.

Join live online, small-group science classes led by an expert, to learn new skills to give you all sorts of science project ideas, including in Quantum Frontiers , NASA Science , Smart Devices , and Minecraft Redstone Engineering .

Discover cool science fair projects

In this list, we will share some awesome ideas for students and educators to get inspired and to make a project that will leave a lasting impression. Of course, there’s a huge gap between a beginner’s project and that of a competitive high schooler, but we have arranged it so you can easily find something for young explorers of all ages.

Explore the best science fair projects for elementary kids

While classic projects like making a cyclone in a bottle or stacking liquids to teach density can make a lasting impact on kids, these projects offer some unique ways of getting elementary schoolers to engage with science.

1. LEGO Zipline

Kids love LEGO and this project only requires a few blocks and some lengths of string. Projects can teach kids about Physics concepts like gravity, tension, friction, as well as Math ideas like slope, angle, and weight. Set a large slope to make the zip line fast, and add slack to the line to slow it down. You could even arrange this project as a race.

2. Slow Ball Race

Another race idea involves building a tower of ramps to allow a ball to roll down. To give your students a unique challenge, instead of making the ball rush to the bottom, you can have them compete to see who makes the ball reach the bottom slowest. All you need are some building materials (paper, cardboard, or plastic) and a ball, ideally something small and smooth like a ping pong ball.

3. Hot/Cold Water Density Project

For this project, students will only need some clear containers of the same size, hot and cold water and food coloring. Students will study the characteristics of water and how its density changes based on temperature. By adding one color to the cold and another to the hot, students then will stack the openings on top of each other, and if done correctly, the different temperature liquids will remain separate. Pretty cool.

4. Soil Erosion in a Bottle

This simple project requires garden soil, some plants with roots in the soil, and three clear soda bottles. After cutting out the side of each bottle, they will then be filled with different materials. In one bottle there will be simple soil, in another the soil could be mixed with rocks, branches, and other large chunks. In the final bottle, students will plant some flowers, whose roots will prevent the soil from eroding. As water is poured through the others, students will witness how plants help preserve and retain our most precious resource: the Earth.

5. Water Filtration

In another climate science project, students will use a variety of materials to experiment with water filtration. By pouring dirty water through a mix of sand, charcoal, rocks, and debris, students can collect the filtered water and demonstrate how clean it is by passing through the filter. This could be a supplement to conversations about the water cycle.

See the best science fair project ideas for middle school kids

Middle schoolers will be able to do more independent projects, and they should have a higher bar for formulating a hypothesis and repeatedly testing it. By analyzing the data in a group, students can improve their verbal reasoning skills in a team.

6. Seed Sprouting Experiment

With some seeds and some containers filled with various growing media (sand, soil, mulch, compost, etc.), students can test which material is ideal for sprouting seeds. Students can also study ideas of sustainability, food security, and climate change/soil erosion as part of their project.

7. Newton’s Balloon Car

“For every action there is an equal and opposite reaction,” is one of the most famous quotes in science and engineering, and one of Sir Isaac Newton’s most famous Laws of the physical world. Middle school students can experience this law first hand by building a toy car that propels itself with the expelled air of an inflated balloon. Kids love this experiment because it can be presented as a race.

8. Geodesic Domes

The geodesic dome joins the arch as one of the strongest physical structures in architecture and engineering. Students can test different materials and design strategies to build a dome that supports as much load as possible. Maybe teams can try to build a structure that carries the load of a human being!

9. The Greenhouse Effect

All students need for this experiment are a jar, some cellophane wrap, a thermometer, and a sunny window. If you want, students can opt for a heat lamp as well. By covering one jar and leaving one uncovered, this experiment can demonstrate in miniature how the atmosphere captures heat and warms the planet. This of course is a perfect experiment to introduce younger kids about the fundamentals of weather and climate science.

10. Coding in LEGO

As Computer Science plays a huge role in shaping the technologies kids love (Did someone say ‘video games’?), no age is too young to learn about coding and computer science concepts like algorithms, loops, functions, and Binary. In these exciting games, students combine their LEGO creation skills to build an algorithm that can be played like a game, using binary to help a LEGO figurine move through a LEGO environment. LEGO was one of our favorite toys as a kid, and this would be an amazing chance to get kids excited about coding early.

To learn beginner-friendly coding with the help of a live expert, join our free Scratch class:

Check out the best science fair projects for high school students

High school science fair projects should be sophisticated and nuanced in their design, analysis, and reporting. Since science fairs can be an important part of getting scholarships and advanced academic placements, high schoolers should be challenged to do college level work in their projects, and hopefully these ideas will help them find something.

11. Enzymes, Yeast, and Cheesemaking

Say Cheese! No, seriously, who doesn’t love cheese? Well, actually the science says that most people are at least a little bit lactose intolerant, but that shouldn’t stop aspiring chefs and chemists from trying out this cool project where students try to use cheesemaking kits to test the chemistry behind this delicious cheese. Kits like the one below are available online and contain not only the materials to make cheese, but also guidelines to build a proper science experiment.

12. Robotics

There has never been a better time to become a robotics scientist. (Seriously, check out the history of robotics !) With the advent of semiconductors, advanced circuits, and tools like 3-D printers and tiny Raspberry Pi computers, students can build a robot from the ground up to solve everyday problems, to interact with humans or nature, to complete human tasks, or to simply tell a story. The possibilities are endless!

To learn more about robotics with the help of a purposeful curriculum and live expert, join our award-winning robotics class.

13. Raspberry Pi

Did we mention Raspberry Pi? Do you want to build your own computer from the circuit board up? These cool little computers are a lot more powerful than their size makes it seem. Students can customize their circuits to build a video-streaming device, a musical instrument like a synthesizer or a drum machine, or a game. There's a bunch of models out there for different budgets or for different purposes, so students should begin with an idea or something they want to do before buying one.

14. Bioassay for Toxicity

In this type of experiment students can test crops for resiliency against drought, flood, or other extreme weather conditions. Students could test to see what level of salt in the soil is ideal for growing crops, and at what point does the salt become toxic? Environmental engineering is a major part in the fight against climate change, and we need scientists to propose solutions to ensure greater food security in the future.

15. Electrolytes in Various Liquids

Is it better to drink sports drinks or a glass of water after a period of exercise? Many products are sold on the promise of delivering electrolytes to help the body recover, but are sports drinks better than a simple glass of orange juice? Using an electrically charged wire, students can test the levels of electrolytes in liquids to both study chemistry and nutrition science in one project.

Bonus. Coding Projects

Now is a great time to learn how to code software. Students have a limitless supply of resources on the Internet, and learning how to do proper Internet research is a fundamental skill for academic success. Students will work in a programming environment like Scratch or Python to build a unique project such as a game to demonstrate their understanding of variables , algorithms , loops , functions, and other CS fundamentals. This project suggests building a program in Python that tests the hackability and strength of passwords.

Enjoy the best science fair project ideas

So that’s our list so far, but there’s a lot of great ideas out there for students heading to their first science fair in elementary school or competing at the national level against the best students in the country. Whether young or old, these projects can turn the key and get kids excited about learning in STEM . Whatever you choose, try to make it stand out by making it your own!

• Problem Solving in STEM

Solving problems is a key component of many science, math, and engineering classes.  If a goal of a class is for students to emerge with the ability to solve new kinds of problems or to use new problem-solving techniques, then students need numerous opportunities to develop the skills necessary to approach and answer different types of problems.  Problem solving during section or class allows students to develop their confidence in these skills under your guidance, better preparing them to succeed on their homework and exams. This page offers advice about strategies for facilitating problem solving during class.

How do I decide which problems to cover in section or class?

In-class problem solving should reinforce the major concepts from the class and provide the opportunity for theoretical concepts to become more concrete. If students have a problem set for homework, then in-class problem solving should prepare students for the types of problems that they will see on their homework. You may wish to include some simpler problems both in the interest of time and to help students gain confidence, but it is ideal if the complexity of at least some of the in-class problems mirrors the level of difficulty of the homework. You may also want to ask your students ahead of time which skills or concepts they find confusing, and include some problems that are directly targeted to their concerns.

You have given your students a problem to solve in class. What are some strategies to work through it?

• Try to give your students a chance to grapple with the problems as much as possible.  Offering them the chance to do the problem themselves allows them to learn from their mistakes in the presence of your expertise as their teacher. (If time is limited, they may not be able to get all the way through multi-step problems, in which case it can help to prioritize giving them a chance to tackle the most challenging steps.)
• When you do want to teach by solving the problem yourself at the board, talk through the logic of how you choose to apply certain approaches to solve certain problems.  This way you can externalize the type of thinking you hope your students internalize when they solve similar problems themselves.
• Start by setting up the problem on the board (e.g you might write down key variables and equations; draw a figure illustrating the question).  Ask students to start solving the problem, either independently or in small groups.  As they are working on the problem, walk around to hear what they are saying and see what they are writing down. If several students seem stuck, it might be a good to collect the whole class again to clarify any confusion.  After students have made progress, bring the everyone back together and have students guide you as to what to write on the board.
• It can help to first ask students to work on the problem by themselves for a minute, and then get into small groups to work on the problem collaboratively.
• If you have ample board space, have students work in small groups at the board while solving the problem.  That way you can monitor their progress by standing back and watching what they put up on the board.
• If you have several problems you would like to have the students practice, but not enough time for everyone to do all of them, you can assign different groups of students to work on different – but related - problems.

When do you want students to work in groups to solve problems?

• Don’t ask students to work in groups for straightforward problems that most students could solve independently in a short amount of time.
• Do have students work in groups for thought-provoking problems, where students will benefit from meaningful collaboration.
• Even in cases where you plan to have students work in groups, it can be useful to give students some time to work on their own before collaborating with others.  This ensures that every student engages with the problem and is ready to contribute to a discussion.

What are some benefits of having students work in groups?

• Students bring different strengths, different knowledge, and different ideas for how to solve a problem; collaboration can help students work through problems that are more challenging than they might be able to tackle on their own.
• In working in a group, students might consider multiple ways to approach a problem, thus enriching their repertoire of strategies.
• Students who think they understand the material will gain a deeper understanding by explaining concepts to their peers.

What are some strategies for helping students to form groups?  

• Instruct students to work with the person (or people) sitting next to them.
• Count off.  (e.g. 1, 2, 3, 4; all the 1’s find each other and form a group, etc)
• Hand out playing cards; students need to find the person with the same number card. (There are many variants to this.  For example, you can print pictures of images that go together [rain and umbrella]; each person gets a card and needs to find their partner[s].)
• Based on what you know about the students, assign groups in advance. List the groups on the board.
• Note: Always have students take the time to introduce themselves to each other in a new group.

What should you do while your students are working on problems?

• Walk around and talk to students. Observing their work gives you a sense of what people understand and what they are struggling with. Answer students’ questions, and ask them questions that lead in a productive direction if they are stuck.
• If you discover that many people have the same question—or that someone has a misunderstanding that others might have—you might stop everyone and discuss a key idea with the entire class.

After students work on a problem during class, what are strategies to have them share their answers and their thinking?

• Ask for volunteers to share answers. Depending on the nature of the problem, student might provide answers verbally or by writing on the board. As a variant, for questions where a variety of answers are relevant, ask for at least three volunteers before anyone shares their ideas.
• Use online polling software for students to respond to a multiple-choice question anonymously.
• If students are working in groups, assign reporters ahead of time. For example, the person with the next birthday could be responsible for sharing their group’s work with the class.
• Cold call. To reduce student anxiety about cold calling, it can help to identify students who seem to have the correct answer as you were walking around the class and checking in on their progress solving the assigned problem. You may even want to warn the student ahead of time: "This is a great answer! Do you mind if I call on you when we come back together as a class?"
• Have students write an answer on a notecard that they turn in to you.  If your goal is to understand whether students in general solved a problem correctly, the notecards could be submitted anonymously; if you wish to assess individual students’ work, you would want to ask students to put their names on their notecard.  
• Use a jigsaw strategy, where you rearrange groups such that each new group is comprised of people who came from different initial groups and had solved different problems.  Students now are responsible for teaching the other students in their new group how to solve their problem.
• Have a representative from each group explain their problem to the class.
• Have a representative from each group draw or write the answer on the board.

What happens if a student gives a wrong answer?

• Ask for their reasoning so that you can understand where they went wrong.
• Ask if anyone else has other ideas. You can also ask this sometimes when an answer is right.
• Cultivate an environment where it’s okay to be wrong. Emphasize that you are all learning together, and that you learn through making mistakes.
• Do make sure that you clarify what the correct answer is before moving on.
• Once the correct answer is given, go through some answer-checking techniques that can distinguish between correct and incorrect answers. This can help prepare students to verify their future work.

How can you make your classroom inclusive?

• The goal is that everyone is thinking, talking, and sharing their ideas, and that everyone feels valued and respected. Use a variety of teaching strategies (independent work and group work; allow students to talk to each other before they talk to the class). Create an environment where it is normal to struggle and make mistakes.
• See Kimberly Tanner’s article on strategies to promoste student engagement and cultivate classroom equity. 

A few final notes…

• Make sure that you have worked all of the problems and also thought about alternative approaches to solving them.
• Board work matters. You should have a plan beforehand of what you will write on the board, where, when, what needs to be added, and what can be erased when. If students are going to write their answers on the board, you need to also have a plan for making sure that everyone gets to the correct answer. Students will copy what is on the board and use it as their notes for later study, so correct and logical information must be written there.

 45+ Engineering Science Fair Projects (and advice!)

Before I started Innovative Arts class, I was a science teacher. The science and engineering fairs were ultra engaging and everyone learned so much! I hope you are excited by the possibilities that lie ahead. A lot of the resources I have created can help you have a great experience.

What is so great about engineering science fair projects?

Engineering science fair projects can be a great way for students to develop problem solving, critical thinking, and research skills in a fun and engaging way. They are challenging! We do our best learning and growing when we are challenged. If you’re looking for some ideas for engineering science fair projects that your child can do at home or in school, here are my best ideas and resources. 

Do some popsicle stick engineering!

This one is my favorite. With a little patience and way to drill a hole in a popsicle stick, you can make a very cool project! Check out my entire page of movements and example videos .

Build Your Own Wind-Powered Car 

For this project, students create a wind-powered car out of everyday materials like cardboard or Styrofoam. It’s great for kids who are interested in renewable energy sources because it gives them hands-on experience building something that runs on wind power instead of electricity or gasoline. Plus, it helps them learn about aerodynamics and basic physics concepts like drag force and momentum—all while having fun!  

If you bring a fan to the fair, you could have a pretty cool demonstration set up for people to play with! Look at possible car projects.

Designing the Strongest Bridge 

In this project, students must design the most durable bridge out of everyday materials such as toothpicks, popsicle sticks, straws, string, etc. It teaches them problem solving skills as they figure out which materials will make their bridge strong enough to withstand certain levels of pressure without breaking down. Additionally, it helps them understand basic physics principles such as tension and compression forces.  

To take it a little further, you could test different designs and display the broken bridges with how much weight it took to break them. Possible bridge projects

Designing Windmills

 Windmills are becoming more popular these days due to renewable energy initiatives around the world. Designing windmills is another great engineering project because it involves researching different types of wind turbines and their associated components like blades and hubs. After researching wind turbine designs students can then go ahead with designing their own prototype using cardboard or other available materials. 

Bring a fan and let your windmill turn while the fair is being judged! Start looking for windmill projects here .

 Creating an Effective Water Filter System 

This project requires students to use everyday items such as coffee filters and gravel to construct an effective water filter system that can clean dirty water into drinkable water. It’s ideal for children who want to learn how filtration systems work since it gives them first-hand experience designing one from start to finish! Plus, it provides important lessons about water purification methods too!  

To do this, research some simple water filter setups and choose an easy option. Make sure you demonstrate it at the fair! I would start here .

Creating Robots

 Another great engineering project is creating robots. Robotics is becoming increasingly important in our society and more companies are investing in robotics research and development every day. To create a robot, students need to understand the components needed such as motors, microcontrollers, sensors, etc., as well as the coding language used to program them. Once these basics are understood students can start designing their own robot prototype! 

There are a lot of kits available for this. I recommend using a robot that can be programmed using Scratch because you can learn it so quickly! See my tutorials below.

Other project ideas available!

I’ve spent years figuring out what works in a middle school classroom using cheap materials. Here are just a few projects from class!

 Engineering science fair projects are a great way for students to apply their knowledge in STEM topics in real life situations while getting creative with their designs at the same time! Whether your child is interested in robotics or renewable energy sources, there’s bound to be an engineering science fair project that fits his/her interests perfectly!

I am creating this site to advance student creativity and help students to take ownership of their learning . The resources on this site are intentionally open-ended and a part of my Innovative Arts curriculum .

Real-World STEM Problems

by Anne Jolly · Published 12/16/2012 · Updated 10/27/2021

A MiddleWeb Blog

Links checked and updated January 2019. See Anne’s recent posts for more real-world STEM.

STEM teachers pose problems and combine problem solving with project-based learning across disciplines. They work together with students on activities to develop students’ critical thinking, communication, assessment, and inquiry skills.

That’s an impressive job description; however, one source describes the teacher preparation system for STEM teachers as “chaotic, incoherent, and uncoordinated, filled with ‘excellent programs, terrible programs, and many in between.’” That’s not surprising, since the STEM acronym has only been around for a few years. But it certainly needs to improve.

What Good STEM Lessons Do

While things seem a bit muddled on the STEM teacher preparation front, we do know some things about STEM curriculum. We know, for example, that a good STEM lesson accomplishes these things:

• Helps students apply math and science through authentic, hands-on learning
• Includes the use of (or creation of) technology
• Involves students in using an engineering design process
• Engages students in working in collaborative teams
• Appeals equally to girls and boys
• Reinforces relevant math and science standards
• Addresses a real-world problem

Providing students with real-world problems and asking them to brainstorm solutions will bring their higher order thinking skills into play. But for me, identifying real-world problems that students can solve is one of the hardest parts of creating STEM lessons.

They have to be problems that students can reasonably grapple with. And those all-important problems may need to synchronize with a specific set of math and/or science standards from the school system’s pacing guide. Hopefully you don’t have that constraint, but realistically you probably do.

Sites for Real-World Problems

I’ve located some sites that help me come up with real-world problems, and I’m always on the look-out for more. I’m going to share several sites I’ve identified, and I hope that you’ll share some as well. I invite you to click on these sites and mull over the possibilities.

In the Greening STEM section on this site you’ll find ideas for relevant problems. Most environmental topics can fit under standards for either life or physical science, so these may provide you with some real “kid-catchers,” or ideas that snag students’ interest.

Topics include areas such as:

•    Oil spills •    Water pollution •    Air quality •    Endangered species •    Environmental Health

Another favorite site of mine is the Design Squad Nation . They have some real-world problems there that I find intriguing. For example student teams might invent these:

•    Band Instrument •    Electric Gamebox •    Confetti Launcher •    Solar Water Heater •    Speedy Shelter

How cool are those ideas? As a middle school science teacher, I found STEM to be a natural fit for most of the topics I taught. Math, however, seems to be a different matter.

The Problem with Math

One issue I hear repeatedly is that math teachers find it difficult to identify real-world problems and implement STEM projects in math classes. (Note that these math teachers are not able to work collaboratively with science teachers to develop/implement lessons, and must therefore “go-it-alone.”) However, the math teachers who mentioned this are looking determinedly for ways to implement STEM lessons.

The Common Core Standards state: “Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace.” This adds urgency to the search for real-world problems that bring in appropriate math standards.

Math standards addressed by the lessons on this site include these and more:

•    Fractions, decimals, percents •    Ratios and proportions •    Estimating and predicting •    Rates and unit rate •    Modeling problems with graphs, tables, and equations •    Comparing, graphing, and interpreting data •    Scale factors •    Geometry and measurement •    Probability •    Proportional reasoning

Another site that links math to real problems is Middle School Math and Science . Students solve problems involving train races, global sun temperature, amount of water usage, and so on. Most of these are Internet-based, so you may want to design some of them as hands-on projects for students. (UPDATE: This Ohio State University site is now an archive, but you’ll still find plenty of useful resources.)

Teach Engineering

No list of real-world problem ideas would be complete without mentioning the Teach Engineering lessons. As you peruse these, read the summary of the lessons rather than relying on the titles. Look for projects that include hands-on ideas, such as those involving microbes, rocket-powered boats, solid fuel reactants, the fisheries bycatch problem , and so on. Notice that many of the lessons have hands-on “Associated Activities.” These generally hands-on investigations bring the “E” in STEM to your students.

I hope these sites will be of value to you, and will assist you in brainstorming ideas for real-world problems. Feel free to share comments or sites of your own. We’re inventing a new specialty and need all the help we can get and share!

Hello Anne. As a new STEM coordinator, I have to give a STEM presentation to principals for my charter schools. Can you suggest and lessons, books. power points,etc. that would be advantageous? Fondly, Linda Schwerer Pinellas Academy of Math & Science

Hi, Linda – I have a couple of ideas . . . If you contact Susan Pruet – Director if Engaging Youth through Engineering (you can google it) she will send you a copy of a free STEM launcher. It’s a lesson intended to demonstrate the STEM process. You could lead your principals through it if you think they really need a better understanding of the difference in STEM and science experimentation. You could also distribute it to your schools for teachers to use as a launcher into the STEM way of thinking. It has PowerPoint slides with it.

An online document that you might like to look at is “STEM Teachers in Professional Learning Communities: From Good Teachers to Great Teaching.” You can google this document online as well as a National Academies Press document titled “Successful K-12 STEM Education: Identifying Effective Approaches in Science, Technology, Engineering, and Mathematics.”

I’m not sure if you’re trying to introduce these principals to the idea of STEM and convince them that they need to do this, or if you’re trying to show your principals how to do this. Those are two separate presentations – at least.

Good luck with your preparation! You have a lot of research to back up the need for STEM!

Thank you so much Anne! I will get to work! Your advice is very helpful!

I realize this comment is 3 years old, but I came across it just now. I would like to know if Susan Pruet is still available to get that free STEM launcher you mentioned – a lesson intended to demo the STEM process. I would love this.

Harry – thanks for asking. This is still a popular post at MiddleWeb! Anne Jolly’s January 2017 blog post shares the Launcher activity: Launch the New Year with STEM Mini-Lessons!

Thank you! Much appreciated from a fellow Alabaman. (correct use of that word? :) )

I love the STEM idea. But, as a 7th grade math teacher, I don’t see a place in STEM programs to ensure that students understand the basic math skills required by educational standards. For many kids, it takes a long time to understand and be able to apply math concepts. With STEM programming focusing on the project-based approach, where does mastering basic skills fit in?

Mastering math skills and applying them through STEM isn’t actually an either-or situation. If kids see reasons for what they are learning, they tend to learn more deeply and quickly because they are actually engaged in the content. I’ve worked with STEM courses that made use of math that the kids had already learned. I’ve also worked with STEM projects that taught the math kids needed in order to solve the problem. Both were effective. The real purpose of STEM is to ensure that math and science students learn their content more deeply. If that isn’t working, then we’ll need to keep adjusting until we get there. Thanks for asking!

Hi Ann, I am a third grade teacher and currently co-chair a curriculum committee to develop a summer program for Kindergarten through 3rd grade. I am having trouble finding age appropriate STEM lessons for kindergarten through 3rd grade. Do you have ideas or suggestiosn as to where I can start? Thank you.

Hi, Mary! So glad you’re working on developing a summer program. I know someone who’s been there, done that, and I’m going to put you in touch with her. Her name is Susan Pruet and her email is [email protected] . Please shoot her an email and she’ll be happy to tell you about what materials, etc. she uses.

I’d also take a look at the Engineering is Elementary (EiE) curriculum from the Boston Museum of Science. Those are quite thorough and good.

Hi Ann I am a seventh grade science teacher and we are in the early stages of implementing STEMS at our school site.Can this program incorporate all content areas, history, language arts, math and science all in the science classroom? This is not my understanding of how it should be taught. I understand the math and science but to include what the history and language art teacher is teaching doesnt seem to work. I am hoping you can clarify this for me.

Hi, Darren. Wow. You’re gonna be sorry you asked me this . . . my answer won’t be short!

For me personally, STEM includes an indepth, integrated focus on science and math, and on using the engineering design process to solve real-world problems. Technology may be used to help with the solution, or teams of kids may create technology as part of the solution. (Anything made by humans to meet a want or need is designated as technology). This in-depth focus on science and math through STEM has come about as the result of a 21st Century workforce with an increasing need in STEM fields and a lack of STEM-prepared workers. The math and science deficits are sending our industries abroad to find workers qualified for our 21st century workforce.

Now to your question. I see a place for art in the STEM product design – it could be used to make the product teams produce more appealing and desirable – although that may be for the art teacher to work with if it’s going to involve knowing art design principles.

Likewise, you have to use some form of language arts in the communication process (communication is part of the engineering design process); however, it’s used naturally as teams work together to solve the engineering (STEM) challenge and to publicize their solutions. It’s not used try to accomplish specific language arts objectives.

History might be incorporated if you need to set some sort of context for the engineering challenge. But I can’t visualize incorporating specific history objectives during a STEM challenge unless they happen to be a natural fit. And unless you need a historical context for the challenge.

Doing a “force fit” with other subjects doesn’t make much sense to me. Not to mention – class time is already at a premium. STEM work, with its inquiry-based approach, already requires more time than a traditional science (or math) class.

The fact that all subjects are not taught directly in an engineering challenge doesn’t lessen the value of those other subjects. Again – it goes back to the need we’re attempting to meet by going deeper in math and science content through an engineering process.

So for me, in a STEM project students focus on using science and math to solve real world challenges, and they use the engineering design process to bring structure and process to doing that. Language arts and history are always appropriate to the extent that (and if) they add value to the STEM challenge. They shouldn’t be add-ons just for the sake of adding them on.

Remember, however, that there is an intense focus on the science and mathematics objectives in a solid STEM program. And this works best when these two subjects are integrated and the math and science teachers work together on teaching STEM projects.

Now, aren’t you sorry you asked? Seriously – remember this is MY opinion and STEM has other looks as well. I’d advise you to listen openly to the need for including other subjects as explained by your principal or other decision-maker. Then – rather than pushing back – in a positive manner explain how these subjects could fit naturally during the course of the STEM projects. Also explain what you expect to accomplish for your students through STEM and note the limited time you already have. Let me know how it goes. :-)

I am looking for STEM lessons that I can incorporate in my middle school Math Enrichment program which is for advanced math students in grades 6-8 and meets for approximately 10 weeks during the school year. I have been given the charge of creating a Math/STEM enrichment program/curriculum and am looking for resources to help. Currently, our school is implementing STEM curriculum/projects in the Science classrooms, but I need to find more of a mathematical slant. Thanks for your help…..I am so glad I found this website!

Hi, Sharon,

Math is one of the under-resourced areas in terms of lessons that apply real, grade-level math. I’ve seen so many lessons that ask students to “find the average” (my math teachers say it should be “find the median”), and then the writer feels that math has been sufficiently covered. NOT! Some areas of math that I’ve seen successfully developed into STEM lessons include applying what middle school students have learned about flow rate, unit rate, scaling and proportion, and statistics, to name a few.

Susan Pruet – a real math guru – will be writing a post for this blog in August. She’s going to address how math teachers can be STEM teachers, and will give some examples.

Some of the better math lessons I’ve found and adapted are from the Design Squad. This one – making cardboard furniture ( http://pbskids.org/designsquad/build/paper-table/ )- uses geometry. Try browsing around there for ideas. The Design Squad site also has links to other sites as well.

I’m SO glad that you, a math teacher, are taking on this task. Applying math will eliminate forever kids asking “Why should I learn this?”

Keep us posted, and stay in touch.

Thanks for your reply. I will be looking for the post in August and I will look at the Design Squad site as well. I too feel that Math takes a back seat to Science when STEM programs are created and implemented. I hope to change that! I will keep in touch and again, I appreciate your reply and support!!

You are providing amazing resources – thank you! I am starting a STEM program for all 6th, 7th and 8th grade students in our middle school. They will have STEM on three consecutive days (3 – 45 minute blocks) for 12 weeks. This will be a very exciting introductory year for us! My challenge is to design the curriculum this summer, though. I am searching for any type of “canned” curriculum to purchase as a start and then to develop from there. Can you provide any suggestions? Thanks so much!

I, too, have been given the charge of STEM curriculum writing for grades 6-8 in mathematics during the summer. If I find anything useful, I could let you know. It is a daunting task!!

Hi Sharon, Yes that would be excellent, and I will do the same! Nancy

I found a great resource for STEM projects on TeachersPayTeachers.com It is: 21st Century Math Projects. The emphasis is on Math, but STEM oriented. Check it out!

I checked it out, too, Sharon . . . I can’t see to what extent it mirrors STEM lessons, but it certainly seems to do so from what I read. And I love the fact that it’s written from a math perspective. Thanks for pointing out this resource!

Wow. What a feat to accomplish over the summer, Nancy!

Several “For purchase” STEM packages are out there, but I can’t recommend any in particular because I don’t know enough about them. You want your STEM program to integrate math, science, and technology, and to follow an engineering design process. (It’s the engineering piece that many would-be STEM curricula leave out.)

I’ll put out the feelers and see if any show up on the horizon. Check my Twitter feed at @ajollygal – I may get some responses there.

Thanks so much, Anne! I am a bit overwhelmed at the moment, but simultaneously excited about bringing STEM to our school! I appreciate any help or guidance – I will check twitter as well.

I am a parent of a 3rd grader who has been given the task of doing a stem project, and I have no idea how to help her, or what I am looking to do. I do not understand what this curriculum is. Can you please explain to me what I’m supposed to be doing with her

STEM curriculum helps kids apply the science and math they learn in a real world situations. Parents can help a lot with the STEM skills kids need. Here are some posts that contain information I wrote mostly for parents. See if these can give you the information you’re looking for. http://www.middleweb.com/3569/10-stem-tips-for-parents/ http://www.middleweb.com/15579/ideas-activities-stem-summer-slide/ http://www.middleweb.com/22787/reinvent-summer-learning-make-it-up/

Thanks for your question, and for looking for ways to help your daughter in STEM!

please suggest me some hands on activity on maths for 10-15 yrs of age

I am a technology teacher for grades 3-5. I am looking for STEM problems my students can do on the computer. Any ideas?

Thanks for the information on applying STEM. I am actually a spatial ecologist that is teaching gr7-9 mathematics at a small school in South Africa. I feel that we came up with a brilliant idea of how to combine Math and STEM (for those Math teachers that were uncertain). I combined our focus on insects (biology) for the term with all the data chapters (collect, organise, summarise, interpret and report). The learners were tasked with creating a question that we wanted to answer regarding insects and using the data cycle/scientific method (above) to develop a plan how to answer this question. The learners decided to do a survey of insects at the school. They set up a plan of how to collect the insects, did so and then analysed the data and reported their findings. They had to include a section on possible errors/bias in their data. I admit that this is one of the easier sections in math to incorporate into a STEM-type approach but I provide it as an example. The kids loved it!

Thank you so much, Marie! Integrating math and science fits naturally in your example. I appreciate your sharing your idea here, and I wonder if you’d allow me to share it on my website – http://www.stem-by-design.com/ .

You are more than welcome to share it. I think often we are unaware of how what we are doing can be related to STEM/is STEM! (Pls leave my e-mail address anonymous). Thank you Marie

Hello, I work in the scholastic department of a wastewater treatment plant. We provide hands on STEM outreach to schools and community. We are preparing for our second year STEM camp for high school students. Last year we partnered with a local university and focused on microbiology and chemistry. This year we are looking for some additional engaging ideas to incorporate into our 5 day camp. Are there any recommendations that you can provide? Thank you

Hi Ron, I am going to be teaching a Medical Microbiology class this fall. I would love to know how you focused on microbiology and what lessons you may have used. The University of Texas has potential to help us. What university department did you work with? Thanks for any help you can give me.

Hi Ann I am a STEM instructor, using lego materials as hands on instruction materials,how do I make my class more interesting and innovative. I need ideas on how to make my class a real world problem solving session,please your kind recommendations. Thank you

Try this idea . . . your kids should have a real reason for building whatever it is they make with the Legos (or any other materials). Suppose they are studying the human body in science. They could use the Legos to construct a prototype of something to solve a problem – perhaps a model of a miniature artificial arm or leg that would help a disabled person, If the kids have a reason for making something and the freedom to come up with their own designs, this often stimulates interest and innovation.

I am looking or some STEAM projects for 4-5th graders to work on in relation to Earth Day. Does anyone have any suggestions? We are just starting to implement these into our classes at school which ranges from Prek-8 so suggestions for any grade level are welcome and I will pass them on.

Thank you for all of your valuable STEM resources! I’ve enjoyed reading/researching through your site!

I am new to teaching a middle school 9-week STEM class for 6th graders. As of right now, my curriculum/materials consist of a canned STEM program that has zero depth.

I’ve been tasked with overhauling the class – developing a true STEM curriculum. Do you know of any middle school models I could research?

I’d appreciate any help.

Hi, Sarah, Take a look at this STEM launcher on my website at http://www.stem-by-design.com/use-mini-lessons-to-launch-stem-projects/ . It will help your kids get engaged with the “E” in STEM. It’s written for use in math+science classes, but it would be simple to modify and use with your kids. I have two more launchers I can send you if you like this one.

Another idea – look around the website while you’re there. There are plenty free resources and tools (click on the tabs at the top) and you are welcome to use (and modify) any of them.

If you want to check out my book – it has suggestions for developing STEM lessons. If you have a chance to develop STEM projects that carry over from one time the kids meet until the next, that’s the best look. If you only see them once a week or so, then that’s a bit more of an issue. If you want to email me we can probably “chat” more over email than here. [email protected]

Thanks for being a STEM person!

Thank you, Anne! I appreciate your suggestions and resources. When you get a chance, I’d love to take a look at the other launchers.

Hello! I am a 11 year old kid going to Somerset Academy. I am doing a STEM project like all of else as well. I am working with two other friends on this project. In our project there is some different things we must do. Most of all we need to make a product that solves an everyday problem. Our group created and idea with ice cream. Our product name is Drip Catch. It is basically a plastic cup for our ice cream cones whenever it melts. The Ice cram will just fall into the cup looking thing. But….. it does not really work. So I am asking for an idea that is a product that solves everyday problems.

I also forgot to mention I am in 5th grade. Please help me. You only need to give me an easy/ OK difficulty stem project. But.. it must be a product we created and it HAS to solve a problem.

What a neat assignment! I like the Drip Catch idea – I wish it had worked. Can you redesign it so that it will work? I think its a great start.

Let me tell you where you can find some good ideas for STEM projects. Go to the Design Squad at http://pbskids.org/designsquad/projects/ . At the top of the page, click on “Design” or click on “Build.” There are some pretty good ideas there.

I read of a group of kids who designed Popsicles with vitamins in them. Here are some other problems kids tackled. http://read.bi/2DoiBSY Just scroll down to see them.

Have you ever noticed that kids on crutches have a problem carrying things around? Is there some sort of carrier that can be added to crutches so that kids can carry things?

Keep your eyes open. Look for a problem you can help in your community or at your school.

Good luck to you and your friends. I hope you’ll come back and post what you finally decided to do. I bet it will be neat!

Thank you very much! I looked at the links you provided and got some new ideas. But.. my friends and I decided to keep doing the Drip Catch idea! But thx for your help! Bye have a great day/

Thanks, Jaden! Let me know how the Drip Catch works. I thought it sounded like a useful and original idea.

Tom is the STEM fair and we finished! It looks amazing. We made the drip catch with a plastic container and cut it into a circle and a hole inside. SO ready for tom!! Thank you so much.

Good luck!!

HI Anne I am in the process of starting a STEM Summer Academy for 6-8 graders, looking for projects in STEM that will motivate the students

Take a look at “Engineering Is Elementary” (EIE) Curriculum Units. You can find them at( http://www.eie.org/eie-curriculum/curriculum-units .) While they are designed for up to 5th grade, they are easily adaptable for older students. Also check out “Engineering Adventures” at https://www.eie.org/engineering-adventures/curriculum-units .

“Engineering Everywhere” (www.eie.org/engineering-everywhere) is a free Middle School curriculum you may like. It’s designed for youth in afterschool and camp programs.

Another place I go for just fun activity ideas is the Design Squad (pbskids.org/designsquad/projects/)

I hope those give you some good ideas!

Thank you I will keep you posted on how it turns out ; any ideas for projects

What a great resource! I am currently teaching in a small school of 22 P-6 students and have been asked to complete a 1-1.5 hour Maths Problem Solving Session with a STEM focus each week with all of the children. Can you please put me in touch with some resources/activities that are hands on and suitable for multi age/abilities?

Hi, Karlene. One resource that seems popular is the Student Teaming Guide, and it’s a free download on my book website (www.stem-by-design.com). To get it, click the tab at the top of the webpage titled Student Teaming Tips. Scroll to the bottom, and download it and share it.

You may enjoy looking around the website as well. You’ll find plenty of free tools, tips, and teaching ideas there. You’ll also find a free STEM Launcher (a mini-lesson called Stop, Drop, Don’t Pop) to introduce engineering to your students. ( http://bit.ly/2Cvb2cw ) Scroll toward the bottom of the page and you will see 3 pdfs you can download, use, and share.

In my MiddleWeb blog I write about all sorts of topics from lesson design to including girls in STEM. You may wish to look at some of those resources as well. In fact, I’ve just posted another launcher there – the ‘Bama Bears – to help kick off STEM (the engineering component) for 2018.

I also came across another good muliti-grade level resource that I think you’ll like. Take a look at this site: http://bit.ly/2IaNeda

I hope some of these help! Thanks for your work with STEM.

I forgot to include the link to my MW blog – it’s https://www.middleweb.com/category/stem-by-design/

I’m involved in our school’s pilot STEAM classes and found the resources in your post helpful. I’ve used TeachEngineering quite often to help me get ideas.

About the problem with maths, we’ve had the same concern but what we’re aiming to do in our next project is getting the students to collect data themselves than using made-up ones. We think that the authenticity of these activities will increase students’ level of motivation.

Great idea, Ms B! Authenticity is, indeed, the key.

Also consider checking out some of the big math grade-level concepts and targeting one or more of those specific concepts for a STEM challenge. We did that with flow rate. We did an environmental STEM project that dealt with water erosion (that was an authentic problem for our school.) The kids used flow rate to measure and calculate the effectiveness of their barriers. Then they redesigned them and got much better results. And . . . they finally saw a practical use for learning how to calculate flow rate!

I am the middle school science teacher at a Christian school and is desirous of coordinating and developing a STEM curriculum. I have heard a lot about STEM but want to have a clear focus on how to start this first in the middle school then to the rest of the student body.

Hi, Edmund, What an exciting adventure – starting to implement STEM in the elementary school. That’s certainly the right way to do it. Start with this article on building a foundation with elementary STEM: https://www.middleweb.com/26244/building-a-foundation-with-elementary-stem/ . If you haven’t checked out my latest book, STEM by Design , it’s published by Routledge/MiddleWeb. Among other things, this book shares practical tips, principles, and strategies for implementing STEM in Grades 4-8. Those principles can be applied at earlier grades as well. You may enjoy looking around the book website as well at https://www.STEM-by-Design.com . You’ll find plenty of free tools, tips, and teaching ideas there. You’ll also find a free STEM Launcher (mini-lesson called Stop, Drop, Don’t Pop) to introduce engineering to your students. I’ve posted another launcher – the ‘Bama Bears – on my MiddleWeb blog site. You can modify both of these to help kick off STEM (the engineering component) for this fall.

hii, i’am education student , and i want to work on stem activity based on problem solving for grade 4 to 6 math student , but i don’t have any idea what should i doo :(

One place to start is looking at issues in your community. Also checking news geared towards kids (news depth, TFK, and National Geographic. Then get creative around the engineering design process.

You might also check out Design Squad Global, Dana. There are a lot of super STEM activities for all grade levels on that site. Good luck with your STEM activities.

Common College Freshmen Fears: How to Overcome Them

How to fix it when brightness is not changing on windows 10, motherboard chipset: what it is and what to look for, brain hemispheres and learning: everything you need to know, samsung galaxy tips and tricks you need to know, elevating user experience with address autocomplete api, how to teach students to make story maps: everything you need to know, addressing your child’s reading issues: everything you need to know, product review of the tribit xsound plus 2, teaching reading to struggling students: everything you need to know, 14 project-based learning activities for the science classroom.

One of the most popular methods of facilitating deep learning in K-12 schools in problem-based learning. It starts, as the name suggests, with a problem. In this model, students are presented with an open-ended problem. Students must search through a variety of resources, called trigger material, to help them understand the problem from all angles. What would project-based learning look like in a subject like science? That’s what I plan to explore in this piece. Below you will find a list of 14 project-based learning activities for the K-12 science classroom.

• Student Farm. Students will learn lessons about science, social studies, math, and economics through planting their organic farm. They can begin by researching the crops they want, figure out what kind of care is needed, and then use a budget to determine what materials they must purchase. They can even sell food from their farm to contribute to a cause or fundraiser.
• Bridge Building. Students begin by studying the engineering of bridge building, comparing the construction of famous bridges such as the Golden Gate Bridge or Tower Bridge in London. Then they work in teams to construct bridges out of Popsicle sticks. The challenge is to get their bridge to hold five pounds (for younger students) or twenty pounds (for more advanced students).
• Shrinking Potato Chip Bags in the Microwave. Students can learn about polymers through hands-on activities using some of their favorite products, like shoes and sporting equipment. As a culminating activity, they can put a wrapper from their favorite chips or candy bar into the microwave for five seconds to learn about how polymers return to their natural state when exposed to the heat.
• Design an App. Students love using the newest apps and games, so take it to the next level by having them design their own! With Apple developer tools, kids can learn how to create an app or online game. They can learn about technology and problem-solving skills while engaged in what they love.
• Gummy Bear: Shrink or Grow? For a project-based lesson on osmosis and solubility, you will just need gummi bears and different liquids and solutions (water, salt water, vinegar, etc.). Children will place a gummi bear in each solution overnight and then measure the results.
• The Old Egg in a Bottle Trick . This old trick is an impressive PBL activity for kids to learn about the correlation between temperature and pressure,. Using just eggs, a wide mouth glass bottle, matches, and strips of paper, children will be able to make an egg “magically” fit through the bottle’s opening.
• Cabbage Acid-Base Indicator . Children will love this hands-on approach to learning how to identify an acid or a base just using purple cabbage and seeing colors change.
• Carnation Color Wonders . An uncomplicated way to teach the importance of the various parts of the flower, the carnation color experiment shows kids how stems provide nourishment to the whole plant.
• Polymers & Pampers . If your middle school scientist has a younger sibling at home in diapers, this is a great PBL activity to teach how polymers are essential for products like diapers.
• Make a Battery Using… Anytime a kid can turn produce into a battery, it is fun! So, why not compare a lemon battery to a potato battery to see which one works better?
• Helmet Drop Test . The helmet drop test is a practical PBL project to teach kids the importance of safety helmets. Simply gather different types of helmets and a several melons. Strap the helmets to the melons and drop each from the same height and measure the results.
• How Much Sugar is in that Soda? . Health-conscious parents will love this PBL activity because it teaches kids how much sugar is in their soft drinks. If you have soft drinks, sugar, and measuring cups, you can do this experiment in your kitchen.
• Ways to Clean a Penny . To teach children how acid reacts with salt works to remove the dullness of pennies, kids can do a simple PBL activity using salt and vinegar. They can also test other acids to compare results.
• Oranges: Float or Sink? . To teach kids about density, all you need are oranges and a bowl of water. You can add to this experiment by testing other fruits with peels.

Did we miss any. Please share your favorite project-based learning activities in the comments below.

And The Biggest Unsolved Problems In Physics Are...

When a researcher asked nobel prize winning physicists and other scientists whether there was any new physics left to discover, this is what they said..

The story has been told many times. At the beginning of the 20th century, physics seemed essentially solved. One or two puzzling phenomena like the photoelectric effect and concerns over black body radiation had scientists scratching their heads but a general feeling prevailed that solving these issues would be dotting the i’s and crossing the t’s.

In the event, these seemingly minor problems required an entire revolution for the laws of physics. And the result — quantum theory and relativity — have become cornerstones of modern science and provided the intellectual bedrock for our 21st century world.

That raises an interesting question for young researchers looking for potential revolutions of the future. For them, the question is: what are the most interesting unsolved problems in science today?

Now they have an answer thanks to the work of Suzy Lidstrom at Texas A&M University at College Station who has compiled a set of answers to this question given by some of the planet’s leading thinkers. By asking these researchers — Nobel prize winners and aspiring young researchers among them — whether there will be new physics, she has created a fascinating insight into the “big problems” of physics and into the opportunities, challenges and potential missteps ahead.

Cosmic Mysteries

The paper begins with William Philips, of laser cooling Nobel Prize fame, arguing that the universe promises new physics galore because only about 5 percent of it is visible to us. The properties of the rest, in the form of dark matter and dark energy, are entirely unknown, and so will offer a rich vein of discovery for science.

Gerrard t’Hooft, with an electroweak interaction Nobel Prize under his belt, takes up the baton with the knotty problem of topological phenomenon in physics and its potential for future discovery.

The composition of the galaxy, Solar System, the Earth plus everything that exists on it are determined by the elements produced in some of the most violent processes in the universe — supernovas, the collisions between neutron stars and between black holes. But scientists know little about the way matter behaves in these events so predicting the abundance of elements is hard.

That will begin to change when an experiment called FAIR — the Facility for Antiproton and Ion Research — comes online in 2027, as explained by Karlheinz Langanke, a theoretical nuclear physicist at the Technical University of Darmstadt, in Germany, and one of the driving forces behind its construction.

One refreshing perspective is the iconoclastic view of Jim Baggot who decries an over-obsession in modern physics with topics such as string theory and the multiverse. He points out that discussion on these topics is largely metaphysical because there is little or no experimental evidence to inform thinking. Science would be better served, he suggests, by focusing on solid state physics or quantum information “where new physics is happening all the time”.

Others point to the nature of entanglement and the problem of how the measurement of a quantum state in one part of the universe can instantaneously influence the state of another in a distant region of the universe. Nobody knows how this happens.

And, of course, no discussion of unsolved problems would be complete without asking how the brain works and what approach will help unravel the mysteries of consciousness.

These are truly profound problems that will require partnerships with biologists, linguists, computer scientists, neuroscientists and others. Whether the physics community is well prepared for these kinds of collaborations is left unanswered.

Nature of Information

A fascinating corollary is the discussion of the role of information in the nature of life. One way of thinking about reproduction is as the transmission of biological information from one generation to the next. Lazaro Castanedo and colleagues point out that in the 20th century, engineers led by Claude Shannon developed powerful models for describing the transmission of information from one location to another. They ask whether the specific problems of information transmission in biology might help develop this classical theory of communication even further.

And so on. This is a fascinating paper that sets out many of the biggest problems in physics in a way that largely avoids verbosity and so is easily accessible.

There is another problem that this paper perfectly demonstrates but fails to mention explicitly — the gender bias in physics.

A quick look at the list of authors makes this bias all too clear and Figure 1, showing many of the authors at a meeting in Prague, is an embarrassment of elderly, white men. Shamefully, that’s probably a fair reflection of the state of modern physics.

If the community really has the ambition to take on the mysteries of the universe in all their glory, it will need all the expertise it can get. That means regardless of gender, race and ethnicity.

Developing Homework Problems to Increase Conceptual Knowledge Development and Sense-making

Principal Investigator:  Jessica Swenson

Abstract: Engineering students spend a significant amount solving homework problems for their technical, core courses. Yet, we know little about what students are doing as they solve these homework problems. Dr. Swenson’s previous work examined student group discourse as they solved assigned homework problems and found students conversations mostly focused on getting problems done instead of discussing concepts and their application. This project will focus on developing homework problems that emphasize making sense of concepts, especially through writing and discussion. Work on this project will include collecting data on current homework problems, developing prompts, and piloting problems with small groups of students.

Impact of Pre-College Computing Education

Principal Investigator:   Adrienne Decker

Abstract:  There are many initiatives in place to introduce computing (and programming) to audiences before reaching university-level education. This project investigates the landscape of pre-college computing education and its impact on those participating. The project is centered around a resource center  which contains curated information about pre-college computing education as published in the literature, a set of validated evaluation instruments for computing education, and resources to introduce newcomers to research in this space. The continued development of this resource center is one aspect of the project, but another is the analysis of the data contained within and the collection of new data about the impact of these activities on participants.

Investigating the Role of Problem Typology in Helping Engineering Undergrads Effectively Communicate Their Experience

Principal Investigator: Andrew Olewnik

Abstract: An important and recognized challenge for undergraduate programs is to provide engineering students with experiences that provide insight on what it means to be an engineer in practice. For such experiences to be truly meaningful to professional formation, students must also be capable of internalizing and effectively communicating insights from these experiences later. In this research to “internalize and communicate experience” refers to a student’s metacognition of their professional competencies and the level to which they can effectively communicate those competencies. This ongoing project explicates a problem typology and reflection framework as context for student problem/project-based learning experiences. Through mixed methods research that includes group problem solving discussions, written reflection, and mock interviews, we are investigating the role of problem typology in helping students to: (i) recognize and orient themselves to different types of engineering problems; (ii) deconstruct and re-synthesize technical experiences in terms of specific professional competencies; and (iii) improve communication of professionally relevant experiences to external parties - i.e. employers.

Open-ended Modeling Problems for Engineering Science Courses

Principal Investigator:   Jessica Swenson

Abstract: The Open-ended Modeling Problems project is working to create new homework problems for technical, core engineering courses that are open-ended (no one correct answer) in nature. These problems ask students to use course content to create a mathematical model of a given real-world scenario. The study examines how students approach these problems as well as how it is developing their engineering judgment. Work on this project includes analyzing previously collected interviews, in-class discussions, and students’ homework, as well as helping the growing research team to develop new open-ended modeling problems.

Problem Typology as a Foundation toward an Engineering Education Problem Database

Abstract: Engineers are known for defining themselves as problem solvers, and solving open, complex problems is recognized as exemplary practice. However, there is no agreement on how an expert behaves in practice, nor is there agreement on specific problems, protocols, or rubrics to assess student learning as they work toward becoming expert problem solvers. Using engineering problem typology and problem solving characteristics described in the literature, this research seeks to develop a standard for categorizing problems along dimensions like structured-ness, complexity, representation, and domain knowledge. This research requires collaboration and investigation across academics disciplines and with experts in the field in order to contribute to our understanding of specific differences and commonality between disciplines at the resolution of the individual stages of the different engineering problem types. Such knowledge could help to inform the pedagogical approaches, assignments, and assessment methods in individual courses, and serve as a foundation for a standardized, community-developed database of engineering problems.

Use of Homework in Problem-Solving Courses

Principal Investigator:   Carl Lund

Abstract:  Multiple iterations of practice and feedback are effective for the development of problem-solving ability. Often in engineering courses each homework assignment is graded and used to assess achievement of course learning outcomes. Feedback to students occurs too late and may be limited to providing a “correct” solution to the homework assignment and, perhaps, a few terse comments written on the submission. Alternative approaches to assigning homework that afford opportunities to fail, receive feedback and learn from mistakes prior to assessment of learning are being studied in this project. These approaches include scaffolded in-class practice, grading initial assignments only on effort and using homework wrappers to better target feedback, combined with explicit instruction of problem-type identification and general solution strategy.

Using Subgoal Labeling to Teach Introductory Programming

Principal Investigator: Adrienne Decker

Abstract:  This project involves the introduction of subgoal labels into the introductory programming class as a pedagogic technique for enhancing student experience and learning. The research team has developed worked examples of problems that incorporate subgoal labels, which are explanations that describe the function of steps in the problem solution to the learner and highlight the problem solving process. Using subgoal labels within worked examples, which has been shown effective in other STEM fields, is intended to break down problem solving procedures into pieces that are small enough for novices to grasp. The developed subgoals are being piloted at various academic institutions in the US in the upcoming academic year. The team is now focused on analysis of the data from the pilot sites and working on issues of deployment and dissemination. In addition, subgoal labels for additional courses beyond the first course are being explored.

Title: comm: collaborative multi-agent, multi-reasoning-path prompting for complex problem solving.

Abstract: Large Language Models (LLMs) have shown great ability in solving traditional natural language tasks and elementary reasoning tasks with appropriate prompting techniques. However, their ability is still limited in solving complicated science problems. In this work, we aim to push the upper bound of the reasoning capability of LLMs by proposing a collaborative multi-agent, multi-reasoning-path (CoMM) prompting framework. Specifically, we prompt LLMs to play different roles in a problem-solving team, and encourage different role-play agents to collaboratively solve the target task. In particular, we discover that applying different reasoning paths for different roles is an effective strategy to implement few-shot prompting approaches in the multi-agent scenarios. Empirical results demonstrate the effectiveness of the proposed methods on two college-level science problems over competitive baselines. Our further analysis shows the necessity of prompting LLMs to play different roles or experts independently. We release the code at: this https URL
