Day 74: Mistakes Whiteboarding, Pie Charts, & Particle Diagrams

AP Physics 1: Mistakes Whiteboarding

Students did mistakes whiteboarding with yesterday’s problems. Energy is clicking nicely for a lot of students, which is great to see. One challenge I’m running into is I’ve got some students who have been struggling to connect variables to physical quantities, and are having trouble making sense of all the different quantities that show up in energy problems. I need to give some thought to how to help these students work on doing more sense making, as well as how I might prevent a similar situation next year.

Physics: Pie Charts

Students worked on some problems sketching energy pie charts. They were pretty successful at identifying the main types of mechanical energy, but placing dissipated energy in the pie charts got tricky. I think my students have a good sense for what the mechanical energy forms are, but not a clear sense of what dissipated energy is. I need to think about how I can help them clarify that idea.

Chemistry Essentials: Particle Diagrams

A lot of my students have been struggling to use particle diagrams in their thinking, so we spent some time today sketching particle diagrams to use the qualitative gas laws we have so far to make predictions about a variety of situations. We also spent some time in whole-class discussion using PhET’s gas properties simulation to define pressure and temperature in terms of particle behavior, which seemed to help.
