Students watch a video explaining albedo and its impact on Earth. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.

Students explore positive feedback effects of changing albedo from melting Arctic sea ice.

Students will watch and examine a NASA animation of Earth’s rising surface temperatures over an almost 150 year period.

The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.
