Physics: Longitudinal Waves

We had some discussion about a high-speed video of a glass breaking due to sound waves to establish that sound is a new type of wave. Afterwards, students made longitudinal waves on slinkys to explore what aspects of our models for mechanical waves so far apply to longitudinal waves.

Chemistry: Leftovers Sim

I was gone on Thursday and Friday and it turns out that on Thursday, while I planned for my students to work on PhET’s Reactants, Products, & Leftovers simulation,  the school’s wi-fi went out. We did that lab today, instead. Students were pretty successful applying ideas from Friday’s lab to the simulation and seemed to build some nice bridges to the more abstract chemical reactions.
