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.
Examine the images to see the projected differences in land use between 1900 and 2100.
Students will describe the changes in a newly-formed volcanic island over the first three years of its life.
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 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.
