In this activity, students will learn about sea ice and land ice. They will observe ice melting on a solid surface near a body of water and ice melting in a body of water.

NASA Worldview is a free online visualization tool that is a great launchpad for learners who are new (or veteran) users of satellite data.

GLOBE protocols and learning activities that complement the Changes in Snow and Ice Extent phenomenon through hands-on investigations are detailed.

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

Background on changing albedo values.

In this activity, students use satellite images from the NASA Landsat team to quantify changes in glacier cover over time from 1986 to 2018. 

Students explore positive feedback effects of changing albedo from melting Arctic sea ice.

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