Science Fair Projects for Kids and High School Students

These 12 sites have hundreds of science fair projects, experiments, and advice to help you create the best science fair project you can. They suggest easy projects for kids and more challenging award-winning science fair projects for high school students. I've used many of them with my daughter and students.

Some of the sites provide ideas. Some give you step-by-step instructions for conducting experiments. Some provide kids advice on creating projects for science fairs. And some have forums where kids can get help when they're stuck. Many of these websites have videos to illustrate their experiments.

Note: Some of these sites have forums, which require registration with an email address. Children under age 13 need parent approval to register and submit questions to these forums.

Science Buddies
Science Buddies

#1 Science Buddies

Strength: Detailed science projects and advice for kids

I most often recommend Science Buddies to students and parents starting work on a science fair project. This is an award-winning site was created by the Kenneth Lafferty Hess Family Charitable Foundation, and has a wealth of resources.

First is the Project Ideas section where you can browse a list of projects by area of study. Or try the Topic Selection Wizard. You answer a series of questions about your science interests and grade level, then you get a list of projects best suited to your situation.

The projects are very detailed. Each includes the background, questions to consider, a list of required supplies and equipment, and step-by-step instructions for the experimental procedure.

The next helpful resource is an extensive Science Fair Project Guide. Here you'll learn more about how to use the scientific method to build your project, how to write your report, and how to display your work. There is also advice on safety procedures, selecting supplies, and techniques.

Finally, you can go to the Ask an Expert Forum if you need more assistance. Look to see if another student has asked a similar question that answers yours. If you've been unable to resolve your problem with the help of a teacher or parent, this group of volunteer scientists will do their best to help you.

The Science Buddies site is easy to navigate. And and the extent of their resources is incomparable.

Cool Science Projects

#2 Cool Science Projects

Strength: Tips for creating award-winning science fair projects

The folks at will walk you through all the steps of creating a science project. You'll find advice and resources for simpler projects for a homework assignment, as well as advice on creating show-stopper competition projects.

There are lots of ideas here by grade level. A few of the ideas have step-by-step instructions for carrying them out. The site's biggest strength is the section it devotes to advice on creating a winning science fair project.

Steve Spanglers Science Experiments

#3 Steve Spangler's Science Experiments

Strength: Entertaining videos of experiments to spark you own project ideas

Steve Spangler's Science Experiments is a particularly useful website for science teachers and homeschool parents. Steve is a teacher's teacher who is televised weekly in Denver and who has appeared on nationally televised shows, demonstrating experiments and explaining the science behind them. He also conducts teacher training seminars throughout the country.

On this site, you can access his collection of science experiments, recipes and projects. His library of projects is accompanied by videos of how to use materials and equipment to conduct experiments. He also has an online store of supplies and equipment.

Steve's delight in science experiments is entertaining, and he'll get you and your kids excited about their experiments too!

Reeko's Mad Scientist Science Experiments
Reeko's Mad Scientist Science Experiments

#4 Reeko's Mad Scientist Lab

Strength: Advice for creating a successful science fair project

Reeko is passionate about science. His passion is contagious at Reeko's Mad Scientist Lab. Reeko takes a humorous and engaging approach to getting kids interested in science.

Reeko's focus is science experiments. He does not provide guidance for school science projects. But his experiments are a breeding ground for science project ideas.

This award-winning site has games, puzzles and quizzes. And there is a new forum where you can ask a question if you're having problems with your experiment or science in general.

More great ideas in "Naked Eggs and Flying Potatoes"

Naked Eggs and Flying Potatoes: Unforgettable Experiments That Make Science Fun (Steve Spangler Science)
Naked Eggs and Flying Potatoes: Unforgettable Experiments That Make Science Fun (Steve Spangler Science)
Written by a former elementary school teacher who has appeared frequently on TV, this book was my students' favorite for science experiments. It's ideal for K-8th grade kids, and gets them excited to "do" science. And it's a great jumping off point for more extensive science fair projects. There are tons of pictures to illustrate the experiment steps, and Spangler writes at the elementary reading level to make it easier for the kids to follow along. My three copies of the book are splattered and dog-eared - the best endorsement I can imagine!
Dragonfly TV Science Fair Projects
Dragonfly TV Science Fair Projects

#5 DragonflyTV

Videos of experiments with accompanying variation ideas for home experiments

DragonflyTV delves into experiments conducted by kids. The folks at PBS Kids Go! offer up plenty of videos of kids conducting experiments.

Then they provide ideas of variations your children can pick from for their own experiments. Or kids can give the Super Science Spinner a whirl until they find an idea they like. DragonflyTV also offers their 12 steps to science fair success.

The Science Club Projects
The Science Club Projects

#6 The Science Club

Strength: Detailed instructions, videos and illustrations of projects

Science Fair Ideas Exchange provides dozens of ideas for projects and experiments. If you need more than written explanations and illustrations, look here. The site is hosted by Bill Beaty of The Science Club.

Many projects are accompanied by a video that shows the key steps in creating your experiment or device. Projects are categorized as simple, medium and advanced.

Some of the video-taped experiments are hazardous, and should be supervised by an adult or conducted only by science teachers.

The Make It Solar Science Fair Information provides detailed information on carrying out a project using the scientific method and steps illustrated here. For teachers who have a website, Make It Solar provides the code to put the illustration at the right into your site with a link to its science fair info.

You'll also find planning guides, research tips, illustrations of display layouts. The site's focus is solar energy, so they furnish details on how to create several solar energy science projects.

MadSciNet Science Project Network

#8 MadSci Network

Strength: Answers to your science experiment and project questions

Created by MadSci Network & Third Sector New England, MadSci Network is a great place to get answers to your science questions. Their extensive questions and answers archive can help you as you build your project.

The MadSci Library provides links to other resources by topic area. Look for answers to common science fair questions at the MadSci FAQ page.

If you can't find an answer in their archives of past questions, submit your own question.

Zoom Sci Science Projects

#9 ZOOMsci

Strength: Kids' comments on how the experiments worked for them

ZOOMsci from by PBS Kids & WGBH has dozens of science activities for children in grades K-8. The emphasis is on having fun with science experiments, as opposed to a rigorous scientific method.

Pick an activity, carry it out, then record your observations and comments on the ZOOMsci site. Personally identifiable information is not collected here.

#10 Scientific Methods at

Strength: Lessons to help kids learn the scientific method

Teachers and homeschool parents can make use of the resources for elementary and middle school students at Scientific Methods at There are presentations to use when teaching the scientific method, as well as printable materials.

For kids, there are links numerous resources to help them learn and remember the steps contained in the scientific method.

One of Mr. Donn's greatest strengths is that his material is readable at the upper elementary age level. So adults don't have to do a lot of interpretation.

Exploritium Science Experiments
Exploritium Science Experiments

#11 Hands-on Activities

Strength: Detailed instructions for experiments

At Exploratorium's Hands-on Activities page, you'll find lots of ideas for experiments and science projects. Activities are grouped by topic such as food, living things, or sports science.

Each activity provides a list of needed materials and step-by-step instructions. Illustrations and photos accompany the instructions. A few even have videos.

Note that some of the activities are not true "activities" but rather information on how something, like cycling, works.

If you are making a model of the solar system to scale, you have to take a look at the Build a Solar System activity. There is a scale calculator that uses the diameter of the sun you plan to create to calculate the dimensions for all of the planets and orbit radius of each planet.

Directory of Science Project Websites


There are more than 25 science fair project and experiment websites listed in LearningReviews Directory of Science Project Websites. Some of the sites have simple experiments for kids to carry out at home. Others have more sophisticated projects for high school students and science fairs. Kids, parents and teachers write reviews about the sites they like best.

Other Science categories on the site help you to learn more about chemistry, astronomy, biology, etc., as you prepare for your science project.

The best science fair projects for your kids answer questions they are genuinely curious about.

They are not so challenging that an adult needs to do most of the work.

      I am mearly an observer at science fairs... have never participated. But the ones I find most fascinating are the ones where the students have 'built' a working experiment, rather than just made a series of charts

      Science is a broad subject wherein student need to interact with each other and share ideas. It is important that students will experience manipulating things such as usually seen around so that students could relate to everyday tasks. Students learn more if they are the one who is making projects instead of parents.

      I think the most important learning is hand on and fun and you certainly provide those opportunities here.

      Never use a kit! I am a physicist who once acted as a judge. Originality is the most important, and that is not in a kit.

      Try something that isn't "typical". Even if it has a likely failure rate - it will a good way to think "outside the box". When I was in middle school - I did an experiment to see if people could "tell" when someone was staring at them. It was fun and unique. The important thing is for the student to be interested in what they are doing - and not just do it to try to win.

      I would have students list their interests, and develop projects around them. For example, one student collected baseball cards. He did a project to test the efficiency of various styles of card protectors.
