**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.

**Physics**

This group added some notation to their graph to find the units on their slope

**Physics: Impulse**

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.
