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.
Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations.
Students observe the surface temperatures of a variety of surface types found in a suburban environment.
Students watch a video explaining albedo and its impact on Earth. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.
This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice.
The Great Smoky Mountains have a unique climate and weather pattern. Students will review a Landsat image and read about the history of the area and why Native Americans called the area āShaconage.ā Then they will answer the questions about what caused the unusual āblue smoke.ā
Using hourly graphs of PM 2.5 data and HYSPLIT model trajectories, students will collect evidence for the effects of fireworks on air quality.
Students observe how air quality changes over time, for a selected location, using data from the United States Environmental Protection Agency (EPA).
