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.

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.

I spent my whole prep period today playing with a site I hadn't seen before: PHYSICS 2000 @ http://www.colorado.edu/physics/2000/index.pl?Page=cover.html.   I need to spend some more time there.

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.

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.

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.

Have you seen the new Crayola Crystal Effects Window Markers? You can draw on windows with these markers. Better yet, you can use these markers to teach students some chemistry! After drawing on a window with these markers and waiting a little while, the marker ink appears to crystalize! Check out the video below to see how they work.

When the gas molecules escape from the marshmallow, they push against the marshmallow, causing it to expand. To see this experiment, play the video below.
