Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations. 

Students connect day/night and seasonal cycles with albedo in the Arctic region. 

This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice. 

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.
