Science fair projects and activities

Last updated: November 9, 2009.

Science is all about putting your curiosity to good use to find out how the world works. As every science teacher knows, a powerful, hands-on science experiment is worth 100 hours of staring at the blackboard. In other words, there's no better way to learn about science than by doing it. This is our short collection of hands-on science activities. Let us know if you find any other good science activity sites and we'll add them in here.
