Albedo & Climate Change

When sunlight reaches Earth, it is either reflected or absorbed based on the properties of the surface it hits. In this activity, students will explore how the amount of light reflected or absorbed by a surface impacts that surface’s temperature, and what this relationship means for climate change on Earth.

Recommended age

This activity is recommended for middle and high school students.

Demonstrations of this activity are acceptable for any K-12 student.

Estimated time

This activity takes approximately 50 minutes to complete.

 

Pre-requisites

Students should be walked through the slides in the Teacher Facing Materials prior to the activity. Otherwise, no prior knowledge is needed.

Learning goals

  1. Define albedo.
  2. Compare how reflective two surfaces are based on their albedos.
  3. Describe the relationship between a surface’s albedo and temperature after being exposed to light.
  4. Explain why Earth’s climate is impacted by a change in albedo.
  5. Describe how climate change impacts Wisconsin.
