Human Graphs: Distance-Time Walks
Pairs receive a distance-time graph and use a marked floor or playground to walk the path, timing segments with stopwatches. They record their data, plot it to verify the graph, and explain speed changes. Switch graphs for a second round.
Differentiate between a distance-time graph and a velocity-time graph.
Facilitation TipDuring Human Graphs, have students mark their starting points with masking tape and call out time intervals aloud so everyone hears the pacing cues.
What to look forProvide students with a pre-drawn velocity-time graph of a runner's race. Ask them to calculate the acceleration during the first 5 seconds and identify the time interval when the runner was moving at a constant velocity. This checks their ability to interpret gradients and areas.
