The science behind this musical instrument, including the concepts of sound, vibration, resonance, and amplification. Why do many things sound different underwater? How are echoes made? Can you feel or see sound? Join us as we delve into the mysteries of sound. This webcast will feature an Aim High student demonstrating how to make a membranophone; Exploratorium physicist Dr. Paul Doherty modeling sound with ringing aluminum rods, corrugated plastic whirlies, and a slinky; and Marco Jordan, lead educator in the Exploratorium's Outreach program, demonstrating sound science with a "whine" glass and a singing bowl. Join the Origins team as they travel to Antarctica. We sent Mary, Noel, Paul, and Julie to explore scientific wonders from McMurdo to the Pole. Learn all about the extreme science being conducted at the South Pole in a daily dispatch from Terra Australis Incognita! The first-ever live event inside the NASA clean room, where space hardware is being prepared for the Hubble Space Telescope. We'll get dressed in "bunny suits" to explore the room and show you the activities of engineers and scientists getting ready for the next Hubble servicing mission in November. Hubble's pictures have changed our understanding of the galaxy. Here we meet scientists who show us how their images have led to new discoveries, then check in on our own imaging project and track its progress. How much time does an astronomer need to get that great picture? We'll talk with scientists about how they determine their experiments, and learn what it takes to make their case for a few minutes of the telescope's time.
