Chemistry 1 – Students played around with the PhET simulation called “Gas Properties.”  We use this as an introduction before doing the gas pressure labs.  For the most part I let students “play,” but I do have them answer a couple of basic questions about how the simulation works.  Because gas is difficult to observe this helps visualize the particles before we go and make measurements on this invisible substance.

Chemistry 2 – Groups whiteboarded an acid/base neutralization reaction.  The problems asked for predictions of unknown molarities or volumes needed to neutralize.
