When watching a small child with a toy car, it is seen that interest in motion comes early. Children often suggest speed through sounds such as "RRRrrrRRRooooommMMMmmmm" as the toy car is made to speed up, slow down, or accelerate through a turn. Older children start to consider force and motion studies in more detail, and experiences in school help students define and refine their understanding of motion. The activity in this article is designed to introduce motion concepts to students through active, hands-on investigation, and to help them activate their prior knowledge about motion. Likewise, it can be developed into a culminating assessment for a unit on force and motion, using higher-order thinking skills to make sense of the experience.
