Modeling Motion: Rolling Cups

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup measurements and the size of the circle. After working individually on the task, pairs share their strategies and come up with a plan to collect more data to develop a relationship. The pairs also evaluate sample work to enhance their thinking processes.
