Educational Module

Arctic Happenings – Global Impacts of the Melting Greenland Ice Sheet and Melting Sea Ice, 1961-2015

In the Arctic region, global climate change is quickly transforming the environment. Melting of the Greenland ice sheet and loss of Arctic Ocean sea ice are two processes that have increased dramatically since the late 20th century. Here, we present a four-part educational module focused on these two processes designed for upper middle school, high school, and undergraduate students. Through this investigative module, students learn critical science skills as they collect, analyze and draw conclusions from data and engage with some of the most urgent environmental questions of our time. Finally, they are challenged to think about how these changes are affecting their lives and the lives of others around the globe. This module’s digital materials are freely available online here, as well as at the Arctic Data Center and include rich video and data resources and step-by-step instructions.
