Greenland, shots taken while flying in a helicopter from the Ilulissat Airport out over the Greenland ice sheet to the remote field camp of researcher Sarah Das. From a small rubber boat on a Greenlandic lake, climate researcher Billy D'Andrea introduces some of the equipment scientists use in limnological sampling. (Limnology is the study of freshwater systems, like lakes.) In this zany competition teachers have ten minutes to create a science activity from a special secret ingredient. This week: dental hygiene products! While hiking back from a research site near Kangerlussuaq, Greenland, Ice Stories correspondent Billy D'Andrea happened upon a Peregrine Falcon scrape. Two falcons, not too thrilled that he was passing by their cliff-side nest, began circling and screaming to chase him off. In this video, listen for the sound of Wheatears (songbirds) chirping and yipping in the foreground. Shots of the calving front of the Jakobsavn Glacier, Greenland's fastest moving glacier. Includes two shots of Mark Fahnestock's helicopter flying over. Arctic Fox kits in the grass. Greenland Ice Sheet shots of melting Climate researcher Billy D'Andrea and colleagues explore the remote "back lakes" of Greenland. To understand how Earth’s climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae. In this zany competition teachers have ten minutes to create a science activity from a special secret ingredient. This week: hair care products!
