Many thanks to Kristen Chauncey for sharing this technique with us. We co-taught the students working on this project.
Kyle and Howard tested the “bounciness” of 3 balls. They chose a tennis ball, a soccer ball, and an exercise ball.
Which ball will bounce the highest, a tennis ball, an exercise ball, or a soccer ball?
The exercise ball will bounce the highest.
Height balls bounced:
The excercise ball bounced the highest. Our hypothesis was correct.
This experiment could be conducted using other types of round balls.
Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data (e.g., number of trials, cost, risk, time), and refine the design accordingly.
