HotWheels Speed Lab with a Distance Time Graph

This is a fun lab to experiment with speed! Supplies needed per group include: make-shift ramp, masking tape, 3 stop watches, meter-stick, hot wheels car and this lab sheet. Students will mark of one, two and three meters with the tape. Three students with stop-watches will stand at each of those meters. Groups will count down and as another student releases their car down the ramp, all stop watches should start their time simultaneously with the release of the car. Each student will stop their timer as the car passes their piece of tape. Students will collect data, graph it, and calculate their average speed using S=D/T.
