Day 68: Whiteboarding, Problem Practice, & Whiteboarding

AP Physics: Energy Predictions

Students whiteboarded drafts of their answer to which interaction dissipates a bouncy ball’s energy. One of the things I like about this activity is every group agreed the table is where most of the energy is dissipated, but there was a variety of evidence cited that gave some good opportunities for discussion. Afterward, I showed a thermal video of a weighted tennis ball and we played with the happy/sad balls and seismic accelerator.

Physics: More Problem Practice

Students got some additional practice with unbalanced forces in 2D. It was one more day than I think was truly necessary for their understanding, but confidence has been a big struggle this year and it seemed to help a lot of them feel like they can do the problems.

Chemistry Essentials: Mistakes Game

I did the mistakes game with yesterday’s problems, and it was very rocky. I think it wasn’t ideal timing to introduce whiteboarding since tomorrow is our last day before break and a lot of students are very restless. I’m also really struggling in Chemistry Essentials, more than when I’ve taught it in past years, to get students focused on chemistry during chemistry.
