Students will calculate how many rubber bands will be needed for a doll to safely bungee jump from a given height (e.g., the balcony of a school auditorium). Students will use knowledge of linear relations to make predictions based on tables, graphs and equations.

CCSS Alignment for Grades 6-9

6.SP.2.Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape. Students will understand the concepts of distribution, center, spread, and overall shape through the data acquired from doll’s multiple bungee jumps.

7.SP.4.Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations. Students will decide whether the number of rubber bands needed for a safe bungee jump will change with the weight of the doll.

8.SP.1. Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association. Students will create scatter plots to represent the multiple bungee jump experiments their group performs.

S-ID.3. Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers). Students will interpret differences according to data sets of multiple groups using different heights for bungee drops and account for effects of outliers.
