Title: The Need for Speed
Description:
After viewing an introductory illustrated podcast on speed, distance, time, and velocity, students explore distancetime graphs using interactive websites. Working in cooperative learning groups, students will investigate the motion of toy pullback racers and collect data to analyze the speed of the cars between various positions marked on the race track. Students will use the data to create graphs, analyze data and present findings to the class.
