Day 129: Rotational Inertia, Board Meeting, & Stoichiometry

AP Physics: Rotational Inertia

Students started a lab to find what affects the rotational inertia of a T made out of PVC. The number crunching on this lab gets hairy enough that I want to reevaluate this lab for next year. One option would be to have students apply a force by pulling with a spring scale or force sensor rather than dropping a hanging mass.

Physics: Board Meeting

Students whiteboarded their graphs for the spring period lab. The results for spring constant didn’t come out as nicely as I hoped; a lot of groups struggled to find that value accurately. We ended up using units to reason through how spring constant plays in.

Chemistry Essentials: Stoichiometry

Students did some written stoichiometry problems. Many of them needed more coaching than I’d hoped, but they were able to connect to yesterday’s lab and use particle diagrams to start putting the pieces together.
