Logistic Growth

Activity Overview

Students are introduced to logistic growth curves using a graphing calculator. Lab data includes the number of bacteria over a 20-hour period. The activity numerically approximates the derivative and uses regression to find a curve fitting the data.

Before the Activity

See the attached Activity PDF file(s) for detailed instructions for this activity.

During the Activity

Follow the procedures outlined in the activity.

Students will:

  • Use numerical data and regression to explore a logistic curve.
  • After the Activity

  • Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
