An introduction to a crowd-pleasing noisemaker called a sound sandwich, which you can adjust to raise or lower its pitch. A detailed demonstration of how to make this primitive wind instrument using little more than a straw, two craft sticks, and some rubber bands. The science behind this instrument, including a discussion of how vibration produces sound, and how long, massive objects vibrate slowly and produce a low-pitched sound, while shorter, less massive objects vibrate quickly and produce a high-pitched sound. Meet glaciologist Slawek Tulaczyk and his team, who work in the fast-emerging field of ice sheet dynamics. They speak to us just after returning from a month at a remote camp on the West Antarctic Ice Sheet. Scientists at Palmer Research Station in Antarctica talk about their research: How is the rich marine ecosystem just offshore responding to melting sea ice and global climate change? Join Exploratorium senior scientist Paul Doherty as he serves up more hands-on activities related to science in Antarctica. Penn State University glaciologist Dr. Richard Alley explains why ice is cool. Today we wrap up our conversations with the ANDRILL scientists (including project leader Dave Harwood) and hear about what lies ahead for the project. Join Exploratorium senior scientist Paul Doherty as he serves up hands-on activities related to science in Antarctica. Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms).
