Activity Overview
In this activity, students will measure the bounce heights of golf balls dropped from a height. They examine the geometric sequence in the successive bounce heights and determine the constant or common ratio and the rate of decay of the bounce.
Before the Activity
Install the CBL/CBR Application on the students' graphing calculators using TI Connect™ or TI-GRAPH LINK™, TI Connectivity cable and the unit-to-unit link cable
Connect the TI-73 to the CBR 2 unit
See the attached PDF file for detailed instructions for this activity
Print pages 131 - 138 from the attached PDF file for your class
During the Activity
Distribute the pages to your class.
Follow the Activity procedures:
Place the CBR at a certain height and drop the golf balls from beneath it
Record atleast 4 bounce heights on each ball
Examine the change in the bounce height of consecutive bounces
Divide a bounce height by the preceding bounce height to determine the common ratio
Repeat the experiment for the remaining balls
Identify which ball will travel the greatest distance
After the Activity
Students will fill in the Data Collection and Analysis Sheet and answer questions listed in it.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
