A detailed demonstration of how to do the Ice Balloons activity, including a discussion of materials needed and strategies for getting learners to ask and then investigate questions about what they are seeing. The science and pedagogy behind this activity, including a discussion of concepts such as density, temperature, thermal conductivity, center of mass, freezing point depression, heat capacity, and the characteristics of the states of water, water vapor, and ice. Also describes strategies for observing, asking questions, and then choosing a question to investigate further. TI staff educator Eric Muller demonstrates a “cool” thing to do with dry ice, and it even relates to the standards!

Terje Isungset is one of Europe's most accomplished and innovative percussionists. With over two decades experience in jazz and Scandinavian music his work travels far beyond traditional boundaries. He's become more like a cross between a sound artist and a shaman. Isungset crafts his own instruments from natural elements found in Norway such as arctic birch, granite, slate, and even ice. At the South Pole, the Ice Stories crew met up with correspondent Zoe Courville just before she and her team embarked on their 3,000 km traverse across the desolate and frigid East Antarctic Ice Sheet. In this video, Zoe gives us a tour of the vehicles they are taking on their cross-continent journey, including their living module, sleeping quarters, and science sled. You might be surprised to know that water is one of the most scarce resources in Antarctica. In this interview from in front of the Canada Glacier in Antarctica’s Taylor Valley, Hassan Basagic from Portland State University describes the essential role of polar glaciers in supporting the bare-bones ecosystems in the Dry Valleys. In this program, learn about meteorite hunting in Antarctica with Ralph Harvey who leads the Antarctic Search for Meteorites program (ANSMET). We talk to photographer John Weller, who spent the austral summer 2008 scuba diving under the ice in Antarctica.
