Metabolic Rates and Global Warming

Classroom/Laboratory Activity

A classroom/laboratory activity to measure the metabolic rate in living organisms and to understand the possible effects of rising temperatures on metabolic rate of these organisms. This activity demonstrates how metabolic activity changes in ectotherms (goldfish) and endotherms (common mouse) at different temperatures.

Students will learn how to calculate metabolic rates in goldfish and common mouse. They will understand concepts such as thermoneutral zone (TNZ), lower critical temperature (LCT) and upper critical temperature (UCT), and assess the effect that rising temperatures have on metabolic activity.

Use this tool to help your students find answers to:

  1. What is metabolic rate and how is it measured?
  2. What is the difference between an ectotherm and an endotherm?
  3. Discuss the results of these experiments in the context of global temperature rise due to climate change.
