Students will observe monthly satellite data of the North Atlantic to identify relationships among key science variables that include sea surface salinity (SS), air temperature at the ocean surface (AT), sea surface temperature (ST), evaporation (EV), precipitation (PT), and evaporation minus pre

This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.

What is the hydrosphere and why is it important?

Explore and connect to GLOBE protocol bundles. Each bundle has related Earth System Data Explorer datasets identified.

Explore and connect to the GLOBE Rivers and Lakes protocol bundle. 

This activity was developed by NASA's Global Precipitation Measurement (GPM) team as an introductory experience to a series of lessons about water resources on Earth.

Students learn how to estimate the "energy efficiency" of photosynthesis, or the amount of energy that plants absorb for any given location on Earth. This is the ratio of the amount of energy stored to the amount of light energy absorbed and is used to evaluate and model photosynthesis efficiency.

Explore the energy and matter cycles found within the Earth System.
