Day 105: Standing Waves, Whiteboarding, & Covalent Bonding

AP Physics 1: Standing Waves

Students worked on some problems for standing waves in pipes. Students seemed to be getting the hang of waves, which is good since we need to wrap up this topic tomorrow!

Physics: Whiteboarding

Students whiteboarded yesterday’s pendulum problems. One problem describes g on the ISS as “close to zero”, with the intention that students treat it as if g were zero, but the wording was enough to trip up a lot of students. I’ve been pushing them to read carefully and pay attention to details in the problem, so this was a good problem to have.

Chemistry Essentials: Covalent Bonding

Students worked on translating between names, formulas, and particle diagrams for compounds with covalent bonds. We didn’t get into how to figure out the formulas from the number of valence electrons, so this ended up being pretty easy compared to the ionic bonding we’ve been working on.
