Physics 11 – This is the lab I settled on for conservation of momentum. Students will use three Direct Measurement videos (dart into cart; Hailey and Connor; Hailey, Connor and Christine) and three videos that they will record themselves of two carts on an air track (head on collision, collision in same direction, collision into a cart at rest). I thought about giving them an Excel spreadsheet for entering in their data, but that would make the experiment very much a “black box”. The amount of time this lab is taking is concerning though.
