Day 135: Whiteboarding

AP Physics: Angular Momentum

Students whiteboarded yesterday’s problems. There was a lot of good discussion; I think rotation is starting to click for a lot of students. I also did a few demos, including one with an RC motorcycle inspired by a Evel Knievel statement prior to a jump over the Snake River Canyon that his biggest fear was accidentally letting go of the gas while in mid-air.

 

Physics: Oscillating Particle Whiteboarding

Students whiteboarded yesterday’s problems. The connections between the math and the big ideas seem to be clicking for a lot of students. One of the questions we discussed is whether the angle of a ramp should affect the period of a cart oscillating on a spring, so I set up the demonstration.

Chemistry Essentials: Percent Yield 

I kept the whiteboarding pretty short since a quiz on percent yield was also on deck for today and the para working with the class had let me know that students had done very well with the problems. We targeted a couple of trouble spots, like a problem where a lot of students dropped a decimal point yesterday, leading to over 800% yield. I was really pleased that students recognized why that was not a reasonable answer, even if they had trouble finding the error.
