Yeast Beasts in Action

Figure from experiment 24 from Middle School Science with Vernier

Introduction

Yeasts are microorganisms. They can break hydrogen peroxide down into water and oxygen gas. In this experiment you will investigate yeast activity in acidic, neutral, and basic mixtures. You will observe yeast activity by measuring pressure caused by the oxygen gas they produce.

Objectives

In this experiment, you will

  • Use a Gas Pressure Sensor to measure pressure.
  • Measure and compare yeast activity in acidic, neutral, and basic mixtures.
  • Make a conclusion about yeast activity.
