What is the hydrosphere and why is it important?

Explore and connect to the GLOBE Urban 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.

Explore and connect to protocols in GLOBE related to the cryosphere. Each protocol has related Earth System Data Explorer datasets identified as well.

A key practice of successful scientists and engineers is the ability to clearly communicate the ideas and methods they develop. Being able to review and critique the ideas of others are fundamental activities of professional STEM professionals.

Many of our archived lessons date back to as early as 2004 when our learning community first formed and unfortunately contain links to content that is no longer updated or exist.  Please note that some of these have been updated, and we continue to update them.  Please check ou

The Earth System Satellite Images help students observe and analyze global Earth and environmental data, understand the relationship among different environmental variables, and explore how the data change seasonally and over longer timescales.  

Explore and connect to the GLOBE Oceans protocol bundle. 

Students will examine a 2014-2015 El Niño Southern Oscillation (ENSO) event to identify relationships among sea surface height, sea surface temperature, precipitation, and wind vectors.

Earth is a system of systems.
