Amazing Albedo

Provided by: American Museum of Natural History |Published on: April 27, 2021

Activity - Outdoors Grades 6-8, 9-12

Synopsis

This simple, hands-on experiment demonstrates the powerful effect of albedo, allowing students to hypothesize what will happen, run the experiment, collect the data, and analyze their results.
Students will learn how albedo affects regional and global temperatures through the reflection and absorption of light energy.
This resource is also included in the Climate Literacy and Energy Awareness Network's (CLEAN) collection.

Teaching Materials

Positives

This is a simple experiment showing the importance of albedo on Earth.
The worksheet includes a place for students to illustrate their conclusions about solar radiation and albedo.

Additional Prerequisites

Each group will need 2 thermometers, black construction paper, white paper, scissors, a stapler, a heat lamp or sunlight, graph paper, and a stopwatch or timer.
Teachers may want to remind students to be careful with the heat lamps, which can get very hot.
Students should have a journal or notebook for responding to prompts.

Differentiation

Science classes can use this experiment in a lesson about the electromagnetic spectrum or heat.
Students can have different jobs in their groups. The worksheet suggests that each group should have a captain and a note-taker.
After the experiment, teachers can show this video on the feedback loop that occurs when higher global temperatures cause ocean waters to warm and melt the ice. Then have students think about how to increase albedo in locations around the world as a climate solution.
As an extension, consider using this TED-Ed video on how the loss of albedo in the Arctic will cause global climate problems and this NASA experiment about how different colors absorb different wavelengths of light.
