Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.

The purpose of this activity is to have students use an Earth Systems perspective to identify the various causes associated with changes to Earth's forests as they review Landsat imagery of site locations from around the world.

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

Students collect and analyze temperature data to explore what governs how much energy is reflected. 

Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes. 

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.

Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017. These data can be used by students to develop their own models of change.

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.
