Join us in conversation with David Ainley and other researchers, as they wrap up there field season at the Adelie penguin breeding colonies in Antarctica’s Ross Sea. 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. What have scientists learned from the South Pole Telescope so far, and what work needs to be done this year as the scientists fine-tune this amazing new piece of technology? Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms). How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it? Join us for an overview of the ANDRILL (ANtarctic geological DRILLing) Project, a multinational collaboration among 200-plus scientists, students, and educators from five nations, to recover sediment cores (layered sections of earth) from under the Antarctic ice and seas. Join us as we talk with Dr. William Fry, emeritus professor at Stanford University and the father of gelotology, the study of humor and laughter, and their effects on the human body. 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. In this zany competition teachers have ten minutes to create a science activity from a special secret ingredient. This week: wire!
