This is Activity 8 from the EXPLORATIONS Book:
EasyData Activities: Modeling Algebraic Functions with Data Collection Activities.

The following materials are required for this activity:
• Small spring cut in half
• Empty plastic cups
• Two large paper clips or string
• Meter stick
• Yard stick
• 30 Candies
• Data from Activity 7: Hooke's Law

## Hooke's Law: The Rest of the Story

#### Activity Overview

Students study Hooke's Law. They explore the linear behavior of a spring as it is pulled downward and understand that stretch on a spring is directly proportional to the force applied to the end of the string. Students create scatter plots, calculate slopes, and discuss positive and negative slopes.

#### Key Steps

• Students develop a formula for the distance from the stick on which the spring is hanging to the bottom of the cup and use list calculations to transform their data from the previous activity.

• Students will then create a scatter plot analyzing the slope of the linear function that is created and then will compare the slopes of the new graph to the graph created in the previous activity.
