The American Chemical Society has a cool website called Chemistry.org which offers activities (both experiments and crafts), interviews with working chemists (in a Flat Stanley kind of way) and other information in a elementary school kid-friendly format.
For older kids, the ACS offers a magazine called ChemMatters, "Demystifying everyday chemistry for high school students and teachers for over 23 years." The site offers free teacher's guides in Word or PDF format. You can also get the last 20 years worth of magazines on CD for $25!

ALSO, for the more experienced chemistry student, there's a cool experiment in Popular Science where you can make nylon fiber in your own home!
