Nailing Density

#### Activity Overview

In this lesson, students will determine the mass and volume of five nails to explore density.

#### Objectives

• Students will determine the relationship between mass and volume.
• Students will mathematically describe the relationship between mass and volume.
• Students will relate the slope of a line to a physical property (density).
• Students will generate a linear least-squares line from mass and volume data.
• Students will analyze a linear mathematical relationship.

• mass
• volume
• density

#### About the Lesson
