It’s that time of year again! The summer is already starting to wind down, the AP Chemistry scores have been released, and now, at the Biennial Conference on Chemical Education (BCCE) 2018 at Notre Dame, Paul Bonvallet and his crew of talented educators have given their analysis and debrief.

Students can sometimes struggle to grasp gas behavior, as it’s much harder to visualize gases rather than readily available solutions, solids, or mixtures. Indeed, for many labs, if gas is a product, we’re often relegated to using balloons or gas columns to capture and measure the gases produced by reactions, which can be tricky or expensive. So this year, I tried something a little different when starting my intro chemistry students’ gas laws unit, and was very happy with the results.
