AP Physics 1: Free Response

We worked a few released free response problems related to angular momentum. I also set up a couple of angular momentum demos, including a spinning Hoberman sphere. Students seem to be grasping the big ideas, which is good since we only have a few more class days before the AP exam!

Physics: Quiz

Students compelted a groupwork reflection, then took their quiz on ray diagrams for shadows and pinholes. I’ve only glanced at their work, but I’m pleased with how the quizzes look.

Chemistry Essentials: Limiting Reactants Lab

Students did a reaction with copper chloride hydrate and aluminum. I had different groups use different quantities so that the limiting reactant varied by group; students were really intrigued by the stark differences in some of the finished reactions. Students did very well using “for every” statements to do stoichiometry when the particle diagrams don’t work. I am glad I introduced the statements yesterday with Pivot; I think starting that skill without having to worry about good lab technique helped it sink in better.
