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

Earth is a system of systems.

Students connect day/night and seasonal cycles with albedo in the Arctic region. 

Students will make a claim about whether changing albedo contributes to changes in Arctic habitats.

Students review a video showing a global view of the top-of-atmosphere shortwave radiation from January 26 and 27, 2012 and answer the questions that follow.

The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using two maps created using NASA satellite data for 2017, students review the seasonal differences of snow and ice extent and answer questions on their observations.
