Wilderness Research Foundation (USA) has developed two teaching modules based on a project we conducted in the Antarctic Peninsula in January 2010. They're available free for any educator interested in reviewing them for classroom use. The project concerned the collection of soil samples for the potential corroboration of a new conception of the carbon cycle. The principal investigator
