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

Students consider the impact of changing conditions on the remote island of Little Diomede, Alaska after they investigate the relationship between seasonal trends in sea ice extent with shortwave and longwave radiation flux described in Earth’s energy budget.

Students will watch a video on the Greenland Ice Sheet and answer questions.

Arctic sea ice is the cap of frozen seawater blanketing most of the Arctic Ocean and neighboring seas in wintertime. It follows seasonal patterns of thickening and melting. Students view how the quantity has changed from 1979 through 2018. 

Students examine the two time series images to determine the differences between seasonal ice melt over water versus land.

Students explore the spatial patterns observed in meteorological data and learn how this information is used to predict weather and understand climate behavior.

Guided by the 5E model, this lesson allows students to work together to uncover how changes in sea ice extent in the Arctic and Antarctic regions are connected to Earth’s energy budget.

This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

Be a Scientist: The GLOBE Program encourages you to use GLOBE data to help answer questions about how the environment works.  Through research projects, you can answer your own science questions by creating hypotheses, analyzing data, drawing conclusions, and sharing your results.  Scientific projects that you conduct and that include the use of GLOBE data or protocols can be submitted by your teacher for publication on this GLOBE website. By sharing your findings with the rest of the world you are completing the scientific process.

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.
