The world's surface air temperature is getting warmer. Whether the cause is human activity or natural changes in the Earth System—and the enormous body of evidence says it’s humans—thermometer readings all around the world have risen steadily since the beginning of the Industrial Revolution. 

In this activity, students make a claim about the cause of ocean currents and then develop a model to explain the role of temperature and density in deep ocean currents.  This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.

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

GLOBE protocols and learning activities that complement exploration of Earth's Energy Budget are outlined.

 Air, Water, Land, & Life: A Global Perspective

GLOBE protocols and learning activities that complement the Changing Albedo Values phenomenon through hands-on investigations are detailed.

GLOBE protocols and learning activities that complement exploration of the Flow of Energy and Matter are outlined.

Explore and connect to the GLOBE Oceans protocol bundle. 

Students analyze four data visualizations focused on the topic of sea level.  They use a jigsaw method to explore and communicate their findings to their peers.

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