Holding Fire in the Palm of Your Hand

Sat, 07/27/2013 - 08:51 -- Tom Kuntzleman

Some students of mine and I have published two papers in the Journal of Chemical Education that describe how stunt people use chemistry to safely set themselves ablaze while filming action movie scenes. The secret behind this stunt lies in the use of superabsorbent polymer (SAP) gels. To pull off this trick...

Summer Inquiry Fun!

Wed, 06/12/2013 - 10:17 -- Sarah Kong

Summer is one of my favorite times as a teacher!  Like most teachers I like to take a little time away from school, but, once I've rested a bit, its my favorite time to do research as well.  I encourage you to take time this summer to explore labs and activities that you think may work for your classroom, but just didn't have time to examine with your busy teaching schedule.

Hydrophobic vs. Hydrophilic, Polar vs. Non-polar

Wow! A very neat experiment, called “Hydroglyphics”, published by Kim, Alvarenga, Aizenberg, and Sleeper in the Journal of Chemical Education allows you to transform a common plastic Petri dish into a unique teaching tool to demonstrate the difference between hydrophobic and hydrophilic surfaces. Check it out in the video.

Fun with M & M's

Sat, 05/04/2013 - 06:35 -- Tom Kuntzleman

I came across a simple, yet interesting experiment that was first described by Elizabeth Sumner Walter in 2001. She merely had students pour water into a dish containing some Gobstoppers candies. I showed this experiment to some of my college chemistry students while they were working on a different laboratory experiment.
