The Calcumites are Coming! - TI-83

Activity Overview

Students model the growth of a population and compare ideal growth with a population whose growth is limited. They use technology to find exponential and logistic regression equations and use them to plot models.

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 39 - 52 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Enter the generation and the number of offspring pairs data for the ideal growth population

Graph a scatter plot

Calculate the slope of sections of the graph and determine the growth rate

Perform an exponential regression on the ideal growth data

Enter generation and the number of offspring pairs data for a population with limited growth

Graph a scatter plot

Calculate the slope of sections of the graph and determine the growth rate

Perform a logistic regression on the limited growth data

Compare the plots for both regressions

Find the number of offspring pairs after 20 generations

After the Activity

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

Review student results:

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

Re-teach concepts as necessary
