Learn how to cast images of the sun using nothing more than a piece of paper and your hands! Musician and comedian Reggie Watts improvises in the Sound Column at the Exploratorium's former home using only his voice and a looping machine. 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. Despite my better judgment, I invite TI staff educator Eric Muller to do one more set of activities—several things you can do with soda straws.
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. Cheer on the competitors in this zany science cook-off. Teachers compete before a live audience at the Exploratorium for the revered title, "Iron Science Teacher." This week's secret ingredient: batteries. TI staff educator Eric Muller hits me up for change, and then demonstrates a neat science activity using dry ice.
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.
