Day 34: Mistakes Whiteboarding, Spring Force, & Card Sort

AP Physics 1: Mistakes Whiteboarding

Students did mistakes whiteboarding using yesterday’s problems. To keep us from getting bogged down in algebra, I had students put their mistake in the diagrams or annotations, then we focused the discussion on getting those parts right and I posted final answers to the class website. Dropping a negative sign was a very popular mistake today, but a lot of students have been making that error, so it was a good one to work on.

Physics: Spring Force

Students finished data collection for the spring force lab. I like to have students collect data for the spring both when it is vertical and when it is horizontal to get the idea that the orientation of the spring does not affect its spring constant.

Chemistry Essentials: Card Sort

Students worked on a card sort based on how Mendeleev worked out his periodic table. I skipped having students do a gallery walk of how other groups sorted their cards before seeing a periodic table, and I wish I’d taken the time to do so since I think it would have gotten students thinking about other ways to sort.
