Boltzmann Bucks—Helping Students Conceptualize Entropy

If you are looking to go beyond using traditional, arguably misleading, definitions of entropy involving “disorder” and “messy bedroom” analogies, the Boltzmann Bucks game fits the bill. The game, pulled from a Journal of Chemical Education article, provides a wonderful opportunity for students to more accurately conceptualize entropy.

Break the Ice with Mystery Blocks

In an effort to align my lessons with the Next Generation Science Standards (NGSS), I have tried to take the content I have traditionally taught, and shift the design to focus on student engagement with the science and engineering practices outlined in the standards. For the topic of heat transfer I re-packaged the ice melting blocks discrepant event as a NGSS investigative phenomena.

A different way to look at heat and energy....

Each year we work on specific heat of materials and the heat of fusion of ice. These are two labs that are typical for most chemistry classrooms. Most of the experiments involve a simple calorimetry experiment that uses a styrofoam cup and provides generally good results. There tend to be a couple of key ideas with all of these experiments.
