PLAYCHEM – COOL CHEMISTRY LAB!
From the Department of Chemistry at Rutgers Univeristy, here is an outstanding collection of short, simple, significant chemistry experiments and demonstrations you can perform. There are some amazing and super interesting activities here – but please note that while most of these are quite safe, some do require fire and specific chemistry equipment and some involve potentially harmful chemicals, so they should only be done with parental supervision. Recommended for jr. high and high school age students.
While this collection doesn’t seem to be on the Rutgers website anymore, the archived site on Archive.org still has most of the experiments available for you to use.
