## Linear Modeling - Barbie Bungee Jump

** Description:**The project has students create their own data and graph it and then choose a reasonable line, which represents their data. The data comes from measurement of how far a Barbie doll bungee jumps, using rubber bands and a tape measure. 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 their doll’s bungee jumping habits using their equation.

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.
