Students will analyze the mapped plot of the historic Ocean Chlorophyll Concentrations at key locations around the world for the period of 1998-2018.

Students review the NASA video showing biosphere data over the North Atlantic Ocean as a time series animation displaying a decade of phytoplankton blooms and answer questions.

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.

By investigating the data presented in a model that displays extreme summer air temperatures, students explain energy transfer in the Earth system and consider the impact of excessive heat on local communities.

Students connect day/night and seasonal cycles with albedo in the Arctic region. 

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

This mini lesson helps students visualize how the Hydrosphere and Cryosphere interact to produce changes in land and sea ice.
