| Title | On A Roll (Force & Motion Series) |
| Synopsis |
The force of gravity makes a ball roll when it is placed on an incline. In this workshop, first-grade students roll balls of different sizes, masses, and materials down ramps of varying heights, comparing their speeds. The students then experiment by replacing the ramp with a cardboard tube, and try to determine how the tube must be oriented to allow the ball to roll, much as it rolled down the ramp.
