Physics 11 – Today the students starting working on the modeling paradigm lab for constant acceleration. Most students used the track and spools that I had made, which have a nice slow acceleration. Others tried using a steel ball rolling down the rails. The ball is difficult to use because it goes pretty fast. However, students started to use the video on their phones to capture position and clock readings. At first they thought they’d use the video timer, but that doesn’t work (I think they’re using slow motion video but the timer doesn’t convert). However, kids started to figure out that they could place a second phone/timer in the video. Smart!
