Ever heard of the popular Bungee Barbie project? In this hands-on and authentic learning project, students must determine how many rubber bands are needed to give Barbie the most thrilling bungee jump from any height while still jumping safely (not hitting the ground).
This fun investigation deepens understanding of linear functions in pre-algebra classroom settings. Using the relationship between the number of rubber bands added to Barbie's feet and the number of inches she drops, students collect data points, create a plot and line of best fit, and write an equation to represent the situation through this SELF-GUIDED PACKET. Each step includes specific instructions and pictures to help guide students through the learning process.
**PRE-REQUISITE KNOWLEDGE NEEDED: linear functions, ratio/rate conceptual understanding, how to solve algebraic equations for a variable value, graphing data points on a graph, determine point-slope OR line of best fit application.
1. Gather supplies: one barbie per student/partnership; rubber bands (10 per student/partnership); yardsticks/meter sticks; printed packet (one per student/partnership); small ladder or ledge 6 feet or higher to drop the barbies from on the BIG JUMP day.
2. Pick 2-3 days for project: 1 day for data collection, 1 day for creation of linear function/equation; 1 day for the BIG JUMP!
3. DO NOT tell students the number of inches that Barbie will drop on the BIG JUMP day! The point is for students to create a linear function that can be solved algebraically on the day of the jump that will tell them how many rubber bands they need for their specific Barbie to ensure she doesn't hit her head on the ground!
