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

Earth is a system of systems.

As a My NASA Data Product Review Team member, you will integrate My NASA Data resources in your classroom and provide valuable feedback to help improve and enhance our offerings. 

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

Students explore albedo, sea ice, and the relationship between changing albedo and changing sea ice using data visualizations. 

Students develop and test a hypothesis about how albedo affects temperature.

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

The My NASA Data program has served the science community sin

Students will watch a short video that explains albedo and how it plays an important role in Earth’s Energy Budget. Applying what they learned from the video, students will analyze a bar graph that lists the albedos of common surfaces found on Earth to answer critical thinking questions.

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.
