Sensor - Gas Pressure

## Boyle's Law

#### Activity Overview

In this lesson, students use the Gas Pressure Sensor in an inquiry activity to understand Boyle's Law through experimentation and data collection.

#### Objectives

• Use a Gas Pressure Sensor and a gas syringe to measure the pressure of an air sample at several different volumes.
• Determine the relationship between gas pressure and volume.
• Use the results to predict the pressure at other volumes.
• Mathematically describe the relationship between gas pressure and volume.
• Evaluate an inverse mathematical relationship.
• Generate and analyze a power regression model.
• Linearize an inverse relation.

#### About the Lesson

This activity makes use of the Gas Pressure Sensor in an inquiry activity that enables the student to understand Boyle’s Law through experimentation and data collection.
As a result, students will:

• Built a mathematical model to show the inverse relationship between gas pressure and gas volume.
• Analyze that mathematical model, and make predictions from the model through interpolation and extrapolation.
• Apply Boyle’s Law to the real-life situation of human respiration.
