This is Activity 7 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

## Hooke's Law

#### Activity Overview

Students study Hooke's Law. They understand that stretch on a spring is directly proportional to the force applied to the end of the string. Students observe a spring being stretched as candies are added to a cup attached to the spring. They learn to graph scatter plots, analyze linear function, calculate and model slope.

#### Key Steps

• Students will collect distance measurements using a CBR2 as a cup hanging from a slinky is filled with candy.

• The data collected will then be modeled using a linear function and List calculations are performed in order to analyze the slope and discover Hooke’s Law.
