Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. See how the quantity has changed from 1979 through 2018. 

Students will explore albedo, sea ice and the relationship between changing albedo and changing sea ice.

Students will use the NASA Earth Observations analysis tool to explore changing albedo in the Arctic compared with other areas of Earth.

Students will make a claim about whether changing albedo contributes to changes in Arctic habitats.
