Ingredients:

1) Motion detectors (obtain these from your friendly, neighborhood Science Department)

2) Eager students willing to run around (available in any classroom)

Have one student hold the motion detector while another student runs towards or away from them generating different position vs. time graphs. It’s important to turn the detector on!

Have the students guess their speed at different times, and then use calculus to calculate their actual speed. How good are these future or current drivers at estimating how fast they are going? 

Collaboration is fun!
