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 video is one in a series of Antarctic Answers that were recorded for showing to high schoolers. The video is 29 seconds long and could be showed as a warm up question about how to become a researcher.
