Free Science Projects for Elementary, Middle and High School

Get a fast start and some great ideas with these 100 science fair projects. Whether you're gearing up for the school's annual science fair or a city-wide or state-wide competition, these projects are an excellent starting point.

They also make wonderful summer projects to keep your kids engaged with science in a fun way. I've recommended many of them to my students. My daughter has done quite a few of them, and won a couple of awards.

The best feature of these projects - they provide detailed instructions.

Also be sure to check out tips from Education.com for kids to create a great science fair project.

Please note that many of the projects require the purchase of supplies or equipment to accomplish them. So as you help your child select a project, keep in mind the cost and availability of materials.

      I confess, I don't have kids. I answered the poll according to my inner child, however. :D I'm glad I found this. I'm writing a book in which several characters do a science fair project and I'm at a loss. Their project will incorporate the strengths of each member of their small group. Thank you.

      @anonymous: there are recipes online to use instead of agar, made from gelatin and sugar or yeast. and one inventive 13-year-old came up with the idea to use large bubble wrap instead of petri dishes. cut the tops off the bubbles and pour your agar substitute in a strip of 4 or five bubbles. just be sure to wash everything you use with hot soapy water first including the scissors or knife. as for the bacteria, get yourself a some q-tips and gather sample from your bathroom, kitchen, doorknob... the list of places to find bacteria is endless.

      I did a great experiment on micronutrients and sunflower growth. Funny thing is, I think I left it in my locker when I graduated...
