On 25 August, teacher Svea Anderson gave a presentation on the highlights from her PolarTREC expedition at the Arizona Sonora Desert Museum at their annual Teacher Appreciation Night.
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

During Lesley Urasky’s expedition, “Glacial History in Antarctica”, the team collected rock samples which were taken back to the University of Washington to be dated using cosmogenic (exposure) dating. This method of radiometric dating measures the ratio of isotopes of Beryllium (9Be:10Be) produced by the interaction of cosmic rays with minerals in rocks. This lesson will introduce the student to
