AP Physics 1: Free-Response
The 2019 free response were released last Thursday. I always have some students interested in discussing the problems, so I offered to go through my solutions with interested students today. The students who opted into the discussion said they struggled in the spots I expected them to, but felt really good about the rest of the problems. We’ll see for sure in July!
Physics: Curved Mirrors
We discussed the results of Friday’s lab, especially some rough ray diagrams I had students sketch. We also got a nice visual of the focal point using a big concave mirror, a ray box that fires several laser beams, and some chalk dust.
Chemistry Essentials: Activity Series
Students combined several different metals and nitrates to rank the reactivity of the metals. One of the reactions is fairly subtle, but students did a nice job of recognizing what was being produced in each reaction.
