Students watch a short video to gather information about sources of methane emissions and then extend their understanding of these sources to evaluate monthly trends in the Alaska region, ultimately making connections to Earth’s energy budget.

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

Explore and connect to the GLOBE Oceans protocol bundle. 

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

In this activity, you will use an inexpensive spectrophotometer* to test how light at different visible wavelengths (blue, green, red) is transmitted, or absorbed, through four different colored water samples.

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