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.

In this activity, you'll explore a frozen water balloon to learn how to ask investigable questions and how to use everyday objects to do experiments to answer those questions.

The film Between the Folds is a 2009 work by filmmaker Vanessa Gould. Between the Folds chronicles ten artists and scientists who have devoted time to the unlikely medium of modern origami. Vanessa Gould, who has degrees in physics and architecture, explores the expression of mathematics through origami. She became captivated by the art and science of transforming sheets of paper into three-dimensional geometric shapes — and exposed a hidden subculture. The film will screen at the Exploratorium on Saturday, October 18th, at 2pm.

Exploratorium staff physicist Thomas Humphrey reveals why size does matter, at least in physics.

Astrophysicist and native Hawaiian Dr. Paul Coleman is used to operating in the worlds of both science and spiritual tradition. But in this short podcast, he tells a story of one time when those two worlds clashed, and he was reminded of the importance of remembering his native roots.

When staff physicist Paul Doherty began to teach, he started by doing lots of demonstrations. But now, he explains, he has students get their hands on the science, which helps them to understand the calculations.
