I had a sub for half the day today, so only saw two of my sections.
AP Physics 1: Problems
Students worked on some problems with angular acceleration. I was at school for my smaller section, and the problems went very smoothly. They worked very independently and I overheard a lot of great discussion and connections to linear motion.
Physics: Mistakes Whiteboarding
I was at school for my only section, so we did some mistakes whiteboarding with Thursday’s problems. Students had some great mistakes and great discussion about the problems. One of the interesting things is when students were asked to sketch a v-t graph and divide it into sections, most groups did before, during, and after, mirroring the way we’d used velocity vs. time graphs during momentum transfer (inspired by Brian Frank). Asking them to tell me about what was happening to the box during each phase was pretty effective at shifting them.
Chemistry Essentials: PhET Limiting Reactants
I was gone for both sections of this class, so it was a great day for students to use PhET to introduce limiting reactants. My co-teacher sent me a message that the kids who got started got the ideas pretty quickly, but a lot had trouble getting started. The para who supports the class was also out today, so I think some students felt like they didn’t have the support they needed; I need to keep working on how to support my chem students in developing independence in the classroom.
