Ice Core Demonstration: The Past is the Key to the Future

Project EXTREMES lessons were written to be stand alone lessons but can be incorporated into a larger unit.

This lesson has students explore how the gases trapped in ice cores over the last quarter of a century can be used to understand how Earth's atmosphere has changed in the past. 

Sea Ice, The Character

Sea Ice, The Character is one of four activities in the The Drifting North Polar Planetarium Experience that invites students to explore what it was like to participate in the MOSAiC expedition to the North Pole.

In this activity, student's will compare and contrast the different structures of freshwater ice and seawater ice with a hands-on lab. Learning about what makes sea ice so unique in the Arctic will be guided by the driving questions: How does saltwater sea ice differ from freshwater ice? What is sea ice like in the Arctic? and Why is sea ice important in the Arctic?
