Day 42: Problems, Practical, & Bohr Model

AP Physics 1: Problems

Students took the plunge to solving problems for objects with a constant acceleration. There was a great moment in one class where a group was struggling with a problem, and a student said “I’m gonna be [calculus teacher]!” He then proceeded to walk the graph while describing his motion to the rest of the group, which was just what they needed to figure out the problem. Thanks, Ms. Hyers!

Physics: Practical

Students did a lab practical where they needed to calculate how much mass to hang off a string in order to balance the forces on a cart on a ramp. Students tested their calculations using mass sets that went down to 10 g, which got them close enough to be satisfying.


Chemistry Essentials: Bohr Model

Students whiteboarded yesterday’s problems connecting the Bohr model of the atom to the periodic table. I remembered today that I want to re-work the problems I have to make the periodic trend in valence electrons pop out. The students who were checked in were feeling very confident by the end of the hour today. The trouble is I’m seeing more and more students check out; I’m wondering if another round of one-on-one conferences might help some students get more engaged by making it clear that they can still improve their grade.
