Measuring Speed

Measuring Speed is a Grade 3 measurement investigation built around toy cars and tracks. Student groups measure car mass and track dimensions, make predictions about which car will be fastest, then time test runs and compare results. The activity combines measurement, data collection, and simple scientific reasoning in a context where students can see the motion they are measuring.

Use it in small groups when you want students to collect real data rather than work only from provided measurements. Comparing hypotheses with timed trials creates a natural discussion about which car or track features may affect speed.
