I had a sub today, so no pictures. All three of my classes worked on problems.

**AP Physics: Angular Momentum**

I gave students some angular momentum problems. Its been a while since we hit linear momentum hard, so I’ll be curious to see how it went shaking the dust off and translating to angular scenarios. I also threw in some torque problems; on the last quiz, a lot of students weren’t sure what an extended free-body diagram is, so that is something I needed to make sure to revisit.

**Physics: Springs & Pendulums**

Students did some problems using the equations for the period of a spring and period of a pendulum. Earlier this week, some students were having trouble distinguishing the two formulas, but I think the lab practicals helped. I’m hoping that shows up in how the problems went.

**Chemistry Essentials: Percent Yield**

Students did some percent yield problems. They look very similar to the stoichiometry problems we’ve been doing, with a step added at the end to calculate percent yield. When I got to school for parent-teacher conferences, I was able to connect with my sub and the para who supports the class, and both told me the problems went very well for the majority of students; they are seeing the connections between what we’ve done previously and the new material. The para also reminded me I need to crack down on students showing their work; a lot of students are frustrated because looking back at their old work isn’t helpful, but they don’t yet see that writing out their work would change that.
