AP Physics 1: Board Meeting
We had a board meeting for yesterday’s lab on Newton’s 2nd Law. Overall, students got very nice results and were very successful at making sense of what they saw.
Students used an elastic string to tie a cart to a force sensor in order to find a relationship between the cart’s change in velocity and the area of the force vs. time graph. I’ve tried this lab a few times without great results, so spent a lot more time on the pre-lab than I had in the past and its looking like results will come out fairly nice.
Chemistry Essentials: Particle Diagrams
Students looked at the change in mass as they spread out a piece of steel wool and started drawing particle diagrams. My co-teacher and I agreed we want to ramp up the graph interpretation in the course, so we made a histogram of the class results and spent a fair amount of time discussing them. Students had some great observations about the graph.
