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 will describe the changes in a newly-formed volcanic island over the first three years of its life.
Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations.
Watch NASA videos about aerosols and volcanic ash.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice.
This lesson contains a card sort activity that challenges students to predict relative albedo values of common surfaces.
This mini lesson engages students by watching a NASA video related to seasonal chlorophyll concentration as it relates to net radiation using NASA's Aqua satellite. Students will examine the model and answer the questions.
Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.
