- Record the successive maximum heights for a bouncing ball.
- Model the bounce height data with an exponential function.
Groups of three students used a motion detector to collect the height of a bouncing ball for 5 seconds.
An example of one group’s data collection.
Students determined the maximum height of five successive bounces. They put the data in a List & Spreadsheets Page.
The data for the first and fourth bounce was used to mathematically determine an exponential model that would fit the data. They plotted their data and model on a Data & Statistics Page.
Then they had the calculator find the exponential regression for their data.
Most groups found their model and the exponential regression to be very similar.
