The science behind this toy, including a discussion of how electric circuits work, and how an unbalanced load (an off-center weight on your jitterbug) results in rotational vibration. Aeolian Landscape is an exhibit in which a miniature wind-swept desert landscape is recreated by an electric fan and finely ground sand that mimics the process of wind picking up and depositing small particles. Visitors can change the direction of the fan, influencing the shape of the dunes. At the Balancing Ball exhibit, a plastic beach ball floats mysteriously several feet above a large plastic cone. Upon closer inspection, the ball is found to be floating on a stream of air blowing out of the cone; visitors interact with the ball, changing its position in relation to the air flow. The Chaotic Pendulum exhibit contains a deceptively simple set of pendulums in a steel and Plexiglas case. The visitor twists a protruding knob, expecting the resulting motion to be fairly predictable. But the device's motion is chaotic, extremely complicated and long-lived. Live program from Side, Turkey Images from the Total Solar Eclipse that took place on March 28-29, 2006. Nadine, a glaciology graduate student from UC Santa Cruz, spent four weeks on the West Antarctic Ice Sheet investigating ice sheets and global climate change. Dr. Tulaczyk, a glaciologist from UC Santa Cruz, studies the lakes, floods, and ice quakes that occur under the giant glaciers of Antarctica. He is among only 200 scientists world-wide who study ice sheet dynamics and its role in climate change. The Exploratorium's Ron Hipschman shows how a double disk with a string attached is a great way to study the physics of motion. Then Captain Yo and Doc Popular astound with amazing yo-yo tricks. Shots of research vessel in the Barrow boat basin near Nuvuk. Daniel Lum talks about the importance of the Bowhead whale to the native Barrow community.
