What are some really good sites for science fair?

Answer 1

Some of my favorite science fair project sites are:

http://www.sciencemadesimple.com

http://www.sciencebase.com/winning_science_fair_experiments.html

http://www.super-science-fair-projects.com

The site in my signature is for a parents' guide, but you'll find some more ideas there that I think you'll like.
