=** Bungee Barbie: Using Barbie to collect and interpret linear data - Part 3 **=

// Traci Seto - Joseph Kerr Middle School //

** Subject Area ** - Math (Algebra) ** Grade Level ** - Middle School

** Overview: ** To make the concept of linear patterns and relationships more concrete, students will collect data using rubber bands and Barbie Dolls and will use the linear relationship of the data to make predictions.

** Objectives: **
 *  Students will understand the purpose of collecting Bungee Barbie data is to see the linear pattern of the data and make predictions using tables, graphs, and graphing calculators.

** Procedure: ** **__ Day 4: __**
 * Students attach their “prediction” number of rubber bands to their Barbie Doll.
 * Barbie Dolls are dropped one at a time from high location (like a roof top).
 * Students watch at bottom as the drops are filmed to check accuracy.
 * Students later reflect on their data collection and data processing and how their Barbie Doll performed in the “big jump”.

** Materials: **
 * 16 Barbie Dolls
 * Rubber Bands

 * Algebra and Functions 1.0 Students express quantitative relationships by using algebraic terminology, expression, equations, inequalities, and graphs.
 * Algebra and Functions 3.0 Students graph and interpret linear functions.
 * Statistics, Data, Analysis and Probability 1.0 Students collect organize and represent data sets that have one or more variables and identify relationships among variables within a data set by hand and through the use of an electronic spreadsheet software program.
 * Mathematical Reasoning 1.0 Students make decisions about how to approach problems.
 * Mathematical Reasoning 2.0 Students use strategies, skills, and concepts in finding solutions.
 * Mathematical Reasoning 3.0 Students determine a problem is complete and move beyond a particular problem by generalizing to other situations.
 * Algebra I
 * Algebra 1.0 Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable.
 * Algebra 4.0 Students simplify expressions before solving linear equations and inequalities in one variable.
 * Algebra 5.0 Students solve multi-step problems, including word problems, involving linear equations and linear inequalities in one variable and provide justification for each step.
