Cricket Thermometers

Activity Overview

In this activity, students investigate the relationship between temperature and number of cricket chirps. They learn to find the other value of a function when given one value of a function. Students use linear regression and plot a set of ordered pairs.

Before the Activity

Set up the calculator for data collection using the procedure described in the attached Appendix PDF file

See the attached PDF file for detailed instructions for this activity

Print pages 1 - 9 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Listen to the chirping, for each temperature record the number of chirps heard in a 15-second time period

Enter the temperature and the chirps per minute data using lists

Set the X and Y extremes and create a scatter plot

Perform a linear regression and study its graph

Enter the number of chirps per minute for the unknown

Examine the graph and record the intersection point of the two lines

The X value of the point of intersection is the temperature of the habitat where the unknown cricket was chirping

After the Activity

Students will complete the Data Collection and Analysis page and answer questions.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
