Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights.

    Great Stem Project!
    Twenty second graders worked on this activity! We had good discussions before the experiment about how to measure, the job that each student would perform in their groups of 2, gravity, bounce properties, but forgot to tell them which end of the meter/yardstick touches the ground! This was another good discussion! The students collected data and compared their results with the other groups! This was an elegant STEM project; it was easy to prepare yet it had such great value to teach /learn about measurement, data analysis, and science topics. I will definitely use this again!
