Antarctic educator, Mark Walsh, created this video for the PolarTREC 2013 spring online professional development course. This video uses the concept of Density to explore how mountains are built as well as how to throw a good Cinco de Mayo party at McMurdo Station Antarctica. He uses the Dr. Samantha Hansen's Transantarctic Mountains work as an example of mountain building.
This short video provides an overview of the types of rocks found in Antarctica and what we can learn about Antarctica from polar geology. This video is designed to accompany the September 2008 issue of the free online magazine, Beyond Penguins and Polar Bears. The magazine is a professional development magazine for elementary teachers.
