**AP Physics 1: Card Sort**

Students worked on Kelly O’Shea’s balanced forces card sort. Since they haven’t seen vector addition diagrams yet, I tried holding those back until they’d sorted everything else, which worked really nicely. I was also much stricter than I was in my regular physics that students needed to sketch the interaction diagrams, and that seemed to really help students think through each scenario.

**Physics: Board Meeting**

Students whiteboarded their results from Thursday’s lab on Newton’s 2nd Law. My 1st hour got pretty nice results, including slopes that came out very close to the masses of their carts, but my 6th hour had much messier data. I ended up telling students to focus on a few specific whiteboards when we were talking about some key points, which seemed to work out fine.

**Chemistry Essentials: Formula Writing**

We started working on writing chemical formulas. I had students sketch simplified Lewis dot structures on whiteboards, then use beans as manipulatives to figure out the correct chemical formula. The students who took the time to sketch and use the diagrams were very successful at thinking through the formulas I threw their way.
