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.

#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.

#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.

SonaNil1 on February 08, 2012:

I always love science projects and my kids won three science fair projects in a row. I have shared one of their project with my readers too..want to add many more.

jimmyworldstar on February 06, 2012:

When I did science projects I'd always have a partner so we'd split between doing research and putting the material on posterboard.

maddydidit on January 30, 2012:

This list is an amazing elementary science fair resource. Thanks so much for your hard work putting it together!

redleafloans on January 25, 2012:

Thank You

For such a wonderful Lens and


diaperbagdiva lm on October 13, 2011:

Can't wait for this stuff!!!

CruiseReady from East Central Florida on September 11, 2011:

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

K Bechand from NY on August 14, 2011:

we haven't really gotten into it yet - but lookin forwarad to it

belindatrisha on August 08, 2011:

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.

anonymous on August 04, 2011:

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

Blackspaniel1 on March 20, 2011:

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.

fluffyclouds on March 18, 2011:

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.

DianaHarper LM on March 12, 2011:

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.

dwnovacek on February 14, 2011:

Thanks for taking the time to put together an awesome compilation lens. So many wonderful sites and projects, so little time. Blessed by your Science neighborhood Squid Angel!

beerhead on February 06, 2011:

Super lens and a great resource!!

WritingforYourW on January 31, 2011:

These look cool--a little more advanced than the volcano made from sugar and potassium nitrate or whatever the combination is. :P

TheCountrySignS on November 28, 2010:

This is great. My Son and I do science projects all the time and I sometimes run out of ideas. Not anymore thanks to your wonderful lens!

javr from British Columbia, Canada on November 24, 2010:

Lots of info to go through here. Thanks!

Paul from Montreal on October 26, 2010:

I just want to know who has the best erupting volcano instructions, that's the number 1 classic!

planproject8 on March 09, 2010:

Really this Science Fair Projects Websites are great. You have also some essential Products in this lens. I may try to review those products.
