Serc: Sea Ice Extension for the Earth as a System Learning Activity

The purpose of this lesson is for students to learn how the Earth's systems interact on a global level. They will examine global environmental data and compare this to data on the polar regions. In the process, they will develop an understanding of how the Earth's systems are interconnected.
