Day 37: Linearization, Force Representations, & Millikan Experiment

AP Physics 1: Linearization

Students linearized their data from yesterday’s ramp lab and used the mean value theorem to make a velocity vs. time graph, then prepped whiteboards.

Physics: Force Representations

Before taking a quiz, students whiteboarded some diagrams based on yesterday’s problems. I really pushed labeling the vector addition diagrams, which seemed to help things click for a lot of students.

We’ve been including a short collaboration reflection at the end of each packet, and I was really pleased when a student working on that said it really makes her think about what she did leading up to the assessment and how it affected her learning, which was great to hear!

Chemistry Essentials: Millikan Experiment

I borrowed an idea from Frank Noschese and had students find the mass of a penny by weighing a whole lot of film canisters with different numbers of pennies inside. Reasoning from the graph was tricky for a lot of students, but they were able to make sense of the stair step graph and reason out the mass of a single penny with some coaching.
