By investigating the data presented in a model that displays extreme summer air temperatures, students explain energy transfer in the Earth system and consider the impact of excessive heat on local communities.

Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.

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.
