This After Dark event explored the diverse nomadic communities that thrive in the Bay Area including a mobile diner, food carts, an annual arts event in the desert, urban foragers, and Bay creatures that arrived by ballast water.
On March 1st, we connected live with scientists aboard the scientific drilling vessel the JOIDES Resolution off the coast of Antarctica. Meet geologists Rob Dunbar, Carlota Escutia, and Christina Riesselman and learn about their historic expedition to Antarctica that is helping reveal the history of Earth's climate and teaching us about our climate future. This short video summarizes all of the steps in collecting an ice core using the Deep Ice Sheet Coring (DISC) drill. Thomas Bauska, of Oregon State University helped Heidi Roop put together this video. As a special event in conjunction with the 2009 American Geophysical Union Fall Meeting, we connected a live audience at the Exploratorium with scientists at the South Pole. Learn about atmospheric research at the South Pole from NOAA's Nick Morgan, the IceCube neutrino detector from Mark Krasberg and Laura Gladstone, and the South Pole Telescope from Bill Holzapfel. Join exhibit developer Charles Sowers as he demonstrates Watch Water Freeze, an exhibit designed to encourage noticing. Patience with this piece is rewarded with breathtaking patterns of ice crystals. Viewed through a polarizing filter, the beautiful colors and crystalline structures of Watch Water Freeze have inspired countless museum visitors to reach for their cameras. See slow-motion footage of flames licking through ice during a demonstration by Eric Muller of the Exploratorium's Teacher Institute. Can you guess what he added to the bottom of the vessel before lighting it?
Most things won't burn on Mars—after all, the main ingredient in the Martian atmosphere, carbon dioxide, is used in fire extinguishers on earth. So how would one create fire without oxygen? Use metal!This slow motion footage shows magnesium burning within a block of dry ice.
Is water ice present or absent in a crater near the moon's south pole? NASA’s Lunar CRater Observing and Sensing Satellite (LCROSS) mission is seeking a definitive answer. Join Exploratorium staff for a special Webcast featuring live coverage of LCROSS crashing into the moon! Our team will be broadcasting live from the 36" Refractor Telescope at Lick Observatory on Mt. Hamilton, where we’ll watch the impact and investigate how this intentional crash could reveal the existence of water ice. 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.
