Even though it was a bit chilly, we had a great time walking outside to the stadium and dropping various objects (some of the more interesting: old globe, broken chair, shoe, empty box) off of the bleachers. Each student captured video of a drop on an iPad and then we retired back inside to use Vernier’s Video Physics and Graphical Analysis apps to graphically and mathematically model the motion of an object falling. We also captured the acceleration of each object on the whiteboard to guide our closing discussion. The first statement shared was that “heavier objects have a greater acceleration.” The second statement shared refuted that idea “except for a couple objects, everything seems to have about the same acceleration.” Then the bell rang. We’ll pick this up on Monday and students may need a reminder about measurement uncertainty.
