After a couple of aborted attempts at finding new and interesting sites, I decided to try my own list of sites -- the one I give to my students.  While most of these are aimed at high achool chemistry students, I thought that some might satisfy this assignment.  I think I found a couple.

You might want to start at:  http://bronstein.home.comcast.net/~bronstein/websites.htm

 I found that http://www.nettrekker.com/ is very useful since it has a number of exercises for kids to follow up on. 

Alsd good is:  http://www.loc.gov/rr/scitech/mysteries/

 http://www.funsci.com/texts/index_en.htm

This site can get kids thinking about alternative uses for everyday items, which admittedly can be dangerous:  http://www.wackyuses.com/uses.html

Some other sites might be of interest, but the above ones, I think, most closely satisfy the assignment.
