Linear Modeling - Barbie Bungee Jump

In-Class Group Activity

Time required: 60+ minutes

Topics:

  • Slope-Intercept Fom
  • Point-Slope Form
  • Linear Modeling (Collect data, Create a linear model to represent data, Use a linear model to make predictions)
Prerequisites: Plotting points, Finding the equation of a line

Material (for each group): Barbie Bungee Worksheet, Barbie doll, tape measure, adhesive tape (e.g., 3M Scotch tape), bag of same-sized rubber bands, graphing calculator, pencil, paper, and straight edge.

Description: This project is excellent when you have completed the chapter on lines. It has students create their own data and graph it and then choose a reasonable line, which represents their data. From there, they find the equation of their line (this will be unique for each group since each will be working with a different Barbie Doll) and answer questions related to the bungee jumping habits of their doll using the equation.
