Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.

Students will watch a video on the Greenland Ice Sheet and answer questions.

Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.

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. Students view how the quantity has changed from 1979 through 2018. 

This lesson contains a card sort activity that challenges students to predict relative albedo values of common surfaces.
