Students used the Sony Motion Shot app (iOS/Android) to create time-lapse photos of the following motions: fast constant speed, slow constant speed, increasing speed, and decreasing speed. They then emailed the photos to my Lensmob photo album so we could see and discuss everyone’s photos. (I set up an album for each period.) This was a nice lead-in to motion diagrams.
(I’m still home today. This was from a few days ago.) Instead of me lecturing or giving notes about velocity-time graphs, students used mini-whiteboards to predict what the graphs would look like for several scenarios involving a buggy moving in front of a motion detector. Here’s the handout: WORKSHEET Drawing Velocity Time Graphs 2015
