The science behind this musical instrument, including the concepts of sound, vibration, resonance, and amplification.

00:00:24
An introduction to a crowd-pleasing noisemaker called a sound sandwich, which you can adjust to raise or lower its pitch.

00:02:32
A detailed demonstration of how to make this primitive wind instrument using little more than a straw, two craft sticks, and some rubber bands.

00:01:48
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.

00:31:28
Hear more from scientists working on the Ice Cube telescope at the South Pole.

00:23:54
Watch as three giant helium balloons are launched above Antarctica to study climate history; listen as scientists talk about balloon research.

00:26:09
Today we wrap up our conversations with the ANDRILL scientists (including project leader Dave Harwood) and hear about what lies ahead for the project.

00:29:33
Watch ANDRILL scientists examine a sediment core, find out about new developments, and discover ancient diatoms (single-celled marine organisms).

00:23:36
How do ANDRILL scientists drill and retrieve sediment cores from under the ice and sea, and why do they do it?

00:31:34
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.
