Day 146: Multiple Choice, Speed of Sound, & Whiteboarding

AP Physics: Multiple Choice

With the AP exam tomorrow, I asked students which of several options they thought would be most useful and both classes requested we use Plickers to review multiple choice. Most students weren’t at their most focused today, but there were still some good discussions.

Physics: Speed of Sound

Students worked on the classic speed of sound lab. Since several labs lately have been pretty rough, I structured the pre-lab discussion more like the way I do in September to get back to basics of experimental design and made sure sketches of the set-up made it onto the main whiteboard. I also took advantage of the fact that students have made other wavelength vs. frequency graphs to emphasize that students should graph as they go to see if their results make sense. My 1st hour got a lot farther than my 5th, but their slopes are coming out very nicely.

Chemistry Essentials: Whiteboarding

The limiting reactant quiz last week did not go as well as I hoped, so we spent some time today whiteboarding a problem, emphasizing the role of particle diagrams. The students who were engaged seemed to get a lot out of the whiteboarding.
