This lesson was created by 2017 PolarTREC teacher Steve Kirsche who took part in the Dynamic Observations of the Microstructural Evolution of Firn expedition. The lesson is intended to introduce students to the concepts of isostasy and postglacial rebound through a demonstration and related instruction. Students will then see how postglacial rebound is an important factor when assessing the
This lesson is intended to introduce students to the concept of using ice core samples to learn about the past. Students will be “collecting” a sample from a model of ice. They will then evaluate the sample to see how the layers change as the depth changes.
Objectives
At the completion of this lesson, students will gain a greater
This mini exhibit explores the science behind climate change and introduces current climate change research to the public. Panels cover the topics of changing climate, ocean acidification and sea level rise, giving examples of how data is collected and current research in these fields. The exhibit also provides websites for further exploring climate change impacts.
Free community viewing of Taking Earth's Temperature -Delving Into Earth's Past followed by Q & A w/contributor Dr. Jason Briner. Organized by PolarTREC teacher, Tina Ciarametaro in her home community after her expedition to Greenland. Learn more here about the documentary Taking Earth's Temperature.
This one hour webinar is part of the International Polar Week celebrations sponsored by APECS, ARCUS and PEI. The presenters are young scientists that work in the Polar Regions. They shared information about their work as well as how they became interested in polar science.
This one hour long event features researchers Karita Negandhi, Brittany Potter, John Lenters, and Reny Tyson. Karita has a marine biology background but currently studying Arctic thaw ponds, while Brittany and John study lakes in Barrow, Alaska and Reny studies humpback whales in Antarctica. This webinar is hosted by ARCUS and the Association for Polar Early Career Scientists (APECS) for
Glaciers are slow-moving masses of ice that exist where more snow falls than melts. They occupy about 10% of the Earth’s land, mostly in Greenland and Antarctica. Here, glaciers can be as much as 2 miles thick and weigh more than millions of tons. As they move, glaciers can widen and deepen valleys, flatten forests and grind boulders
To compare the conductivity of freshwater and seawater. This is a lab activity, and students should be taught appropriate safety measures, including eye protection and safety while using electricity.
