The Exploratorium crew got the opportunity to enjoy a bird's eye view of the Black Rock desert. Join us as we investigate the challenges of navigating density altitude in this extreme climate. An introduction to the Ice Balloons activity, in which learners explore globes of frozen water and learn how to ask and then answer 'investigable' questions. 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. 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. This special edition of Iron Scence Teacher is part of our celebration of the Teacher Institute's 21st birthday.

The only thing to beat out Iron Science Halloween! Holiday madness right when you could use a laugh.... today's secret ingredient: fruitcake! Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. Tee off with this week’s “secret” ingredient-aluminum foil! Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week’s “secret” ingredient-aluminum cans! Julia Child and physicist Philip Morrison once cooked up (and sampled) "primordial soup," a mixture of ingredients said to be the materials from which life sprang on Earth. How accurate is this notion? David Deamer studies how some molecules self-assemble into order, and has developed new theories about how life evolved from components on Earth. We’ll talk with him, do hands-on experiments, and watch vintage footage of Julia Child tasting the soup. Guests: David Deamer, Director, UC Berkeley SETI Program, and Karen Kalumuk, Exploratorium staff scientist.
