Looking for an easy, hands-on experiment to use in your classroom at the beginning of the school year? In the June, 2013 issue of the Journal of Chemical Education, Isao Ikemoto and Kouichi Saitou describe a simple experiment to demonstrate the electrolytic dissolution of copper ions from a copper electrode. This experiment can be conducted using only items that are easily obtained around the home or in grocery stores.
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 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.
Call for Symposia and Workshops for the 23rd BCCE at Grand Valley State University – Greener on the Grand: Empowering Chemical Educators for a Greener Tomorrow, August 3 – 7, 2014
I’d like to report on one of the end-of-year research projects that two of my general chemistry students completed during class this year.
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.
This 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.
Inquiry is a fluid concept. There are some truly fabulous activities on Grand Valley State University's Target Inquiry (TI) website (www.gvsu.edu/targetinquiry). Yes, I am biased as I was part of the first TI cohort, but there are several labs now that were written later and they, too, are terrific.
