Activity Overview
In this activity, students' will create a Height-Time plot for a bouncing ball. They will examine how the ball's height changes mathematically from one bounce to the next.
Before the Activity
Connect the CBR™ to the calculator using the link cable
Run the Ranger program on the calculator
See the attached PDF file for detailed instructions for this activity
Print pages 33 - 37 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Position the CBR at shoulder-height and hold the ball 0.5 meters below it
Release the ball and observe the height versus time graph on the calculator screen
Record four complete bounce heights
Calculate bounce ratio as a percent
Compare rebound percent for different starting heights
Repeat the activity with other types of balls
After the Activity
Students' will collect data and analyze the results.
Review student results
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
