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.

Day 66 – Fnet Direct Measurement Video

Physics 11 – Students analyzed a video which shows a fan cart accelerating on a low friction track. Through some data recording and calculations students were able to find the force of the fan and the acceleration of the cart.
I’m very unsure of the usefulness of this lab activity. The real goal of seeing and thinking about force and acceleration is likely being lost in calculations and figuring out what is going on with the video.  Stay tuned for next class…
