Students observe the surface temperatures of a variety of surface types found in a suburban environment.

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

Students observe seasonal images of Monthly Leaf Area, looking for any changes that are occurring throughout the year.

This mini lesson engages students by watching a NASA video related to plant growth activity around the world using data from the NASA/NOAA Suomi NPP satellite and answering questions on these stability and change relationships.

Students observe the map image, individually, looking for changes in surface air temperatures (using data displayed, unit of measure, range of values, etc.) and noticeable patterns.

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.
