Day 39: Graph Stacks, Vector Addition Diagrams, & Review

AP Physics 1: Graph Stacks

Students worked on sketching stacks of kinematic graphs. I had a sub during my 2nd hour, so I’m not sure yet how it went, but my 4th hour had some great discussions. I’m looking forward to whiteboarding these problems tomorrow.

Physics: Vector Addition Diagrams

Students worked on some problems using vector addition diagrams. I had a sub during my 1st hour, so only got to see things in my 6th hour. A lot of students had trouble with the idea that the arrows on the vector addition diagram need to have the same orientation as the arrows on the free-body diagram, but I think they made progress on the idea.

Chemistry Essentials: Review

After some wrap-up on yesterday’s lab, we did some whiteboarding to review the key ideas that will be on tomorrow’s quiz, including the main atomic models we talked about and key trends on the periodic table.
