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. Geologist Chistina Riesselman explains how studying 3-million-year-old sediment from Antarctica is providing a glimpse of what our planet's climate might look like if atmospheric carbon dioxide continues to rise as projected. TI staff educator Eric Muller demonstrates a “cool” thing to do with dry ice, and it even relates to the standards!
TI staff educator Eric Muller hits me up for change, and then demonstrates a neat science activity using dry ice.
In May 2009, the ROV Jason captured these images of violent explosions of the West Mata volcano near Fiji. At almost 4,000 feet underwater, this is the deepest erupting volcano ever witnessed and captured on video. It's also the first time anyone has ever observed the formation of deep-ocean seafloor as it's happening. 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. We speak with biologist David Ainley, who has been studying Adelie penguins in Antarctica for more than 25 years 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.
