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

Students interpret a double bar/column chart comparing the number of tropical cyclones in different locations.

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.
