AP Physics 1: Assessment

Students took their quiz over angular momentum, and we have now officially finished content. Wooo! 2 class days to spare!

Physics: Reflection Lab

We got out the geo mirrors and some plane mirrors to start exploring reflection. I like to start each optics topic with a lab making qualitative observations. The instructions I gave students today need some work; students had trouble parsing the wording to make meaningful observations.

Chemistry Essentials: Backwards Problem

As a quick warm-up before taking the limiting reactants quiz, I had students whiteboard what I called a backwards problem. I gave them a reaction and told them what should be the limiting reactant, then had them sketch a particle diagram for a situation showing starting conditions that would lead to the right limiting reactant.

A few kids were feeling stressed out about this quiz, so we also took a few minutes to revisit the reassessment policy, including the fact that I’m putting retakes into our normal assessment process, which helped lower the stakes and let students feel a little calmer about the quiz.
