Features 13 core lab activities coverign the fundamental concepts of physiology, ecology, plant systems and more

Yeast Growth

Lab Summary

Use a temperature sensor and absolute pressure sensor to measure the change in pressure inside a flask of fermenting yeast cells at two different temperatures.

Theory

In this activity, students investigate fermentation by yeast cells using an absolute pressure sensor.

Additionally, students will be able to:

  • Explain the fermentation process
  • Describe the role of yeast cells during fermentation

 

Method

Students gain experience conducting the following procedures

  • Setting up the equipment and work area to measure the change in pressure in a flask as yeast cells undergo the fermentation process
  • Measuring the change in pressure inside a flask of fermenting yeast cells at two different temperatures
  • Comparing results with classmates to draw conclusions about the effect of temperature on the rate of fermentation of yeast

Sensors / Equipment Used:

PASPORT Chemistry Sensor

(PS-2170)

Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
