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

Examine the images to see the projected differences in land use between 1900 and 2100. 

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.

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