Day 86: Projectile Practical, Bouncy Ball CER, & Lauric Acid Phase Change

AP Physics 1: Projectile Practical

Students started working on predicting where a marble rolled off the edge of a table will hit the floor. As a wrinkle, I left it open how to set up a ramp to launch a marble and how to measure the horizontal velocity, then had students write a procedure. Groups exchanged procedures with the goal that they should get the same velocity as the group who wrote the original procedure. My goal is for students to get some low-stakes feedback on this kind of writing.

Physics: Bouncy Ball CER

Students finished up with the bouncy ball lab we’ve been working on and whiteboarded CER statements for what is dissipating the bouncy ball’s energy. There was good consensus that the impact has a much bigger effect than air resistance. We used a worksheet to scaffold the pre-work for this activity, so there wasn’t as much variety as when I leave it wide open, but I think students were more successful than they would have been without it.

Chemistry Essentials: Lauric Acid Phase Change

Students collected data for phase changes of lauric acid. A few groups weren’t stirring, which made their data messier, but the patterns are pretty clear overall, even on the data table.
