Fun with M & M's

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 Adaption

Inquiry is a fluid concept.  There are some truly fabulous activities on Grand Valley State University's Target Inquiry (TI) website (  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.

Celebrate Earth Day April 22nd

Celebrate Earth Day, which is on Monday, April 22, 2013. Earth Day was first officially recognized on April 22, 1970. This year the theme is "Our Earth: Handle with Care." The topics this year include water, air, plants/soil, and recycling.

Publishing Your Work

Whether it is a completely unique idea or just a twist on an old classic, engage in collaboration with other chemistry teachers around the world and publish your work. There are many venues and the pool of precollege chemistry instructors that are already contributing is relatively small.

Gas Laws—Finally an app for that!

Moving from the computer lab to iPad? Then you need some apps. I have found two free apps that I use to replace computer-based gas laws simulations.

NSTA Activities

At NSTA (in beautiful San Antonio, Texas), this past week, I shared activities designed to explore three levels of representation AND provide formative assessment techniques to reveal student misconceptions. All of the activities shared have been featured in the Journal of Chemical Education or have been linked to research articles in JCE as supporting information.
