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.

00:07:39
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.

00:01:03
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.

An Exploratorium and NASA Sun-Earth Connection Education Forum Event

Overnight eclipse viewing party at Exploratorium begins July 31, 2008 at 9pm. and continues through Friday, August 1 in the wee hours.

San Francisco's Exploratorium brings its fifth eclipse expedition team to remote Xinjiang Province in Northwestern China, very close to the Mongolian border, where the Exploratorium will webcast a total solar eclipse live to the world. Spend the Night at the Exploratorium! See the eclipse in person live at the Exploratorium. Pack your sleeping bag and camp out on the museum floor for an overnight eclipse party...or come to the viewing party in Second Life and enjoy the live webcast, exhibits, and music.
