Live event on 14 October 2019 with PolarTREC educator Katie Gavenus aboard the Russian R/V Federov as part of the MOSAiC Expedition. Katie spoke with and answered questions from students at Brevig Mission school in Alaska.
Ice that forms in the polar oceans is an important driver behind the global climate. This ice is physically different from frozen precipitation in a number of different ways. In this brief inquiry activity, students make qualitative observations about two types of ice cubes and deduce ice composition based on their observations. This activity may serve as an introduction to
Online newspaper from Massillon, Ohio interviews teacher Deanna Wheeler about her second PolarTREC expedition to the Arctic and describes how her students have become directly involved in arctic studies.
This press release in the Bayonet online newspaper from Maryland outlines teacher Deanna Wheeler's second "educational experience of a lifetime" in the Arctic with PolarTREC.
The attached PowerPoint is an introduction to thermal stratification and turnover in lakes, and interpretation of temperature profile data. The stand-alone presentation can be used to complement a lesson in Earth Science.
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 learn about the effects of air pollution on Sea Ice. This can be a library/computer lab-based activity.
Procedure
Teacher:
1. Mix up a 3.5% solution of NaCl. Make enough "sea-ice" cubes for each pair of students
2. Make another class set of ice cubes with tap water. Leave the ice in the freezer until after the
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.
Procedure
1. Use the table in attached PDF to record your data.
2. Put 100 mL of 3.5% NaCl solution into a 250 mL beaker.
3. Attach 2
