Exploratorium staff physicist Thomas Humphrey divulges a clever way to measure the speed of sound, and he explains how he’s used that information to measure things in the world. Our host, Stephanie Chasteen, shares some more fun facts and activities having to do with the science of sound.
An introduction to how to make your own simple speaker, which transmits sound from a radio or MP3 player and demonstrates the principles of electromagnetism and vibration. A detailed demonstration of how to make a cup speaker, including a discussion of materials needed. The science behind the Cup Speaker activity, including how electromagnets work, and how in this activity the magnet pushes the bottom of a cup back and forth, vibrating the air and creating sound. Our host, Stephanie Chasteen, shares some fun facts and activities having to do with the science of sound.
Learn how to build a version of a Brazilian instrument called the cuica, which demonstrates principles of sound. This podcast was created collaboratively in a teacher workshop at the Exploratorium.
Terje Isungset is one of Europe's most accomplished and innovative percussionists. With over two decades experience in jazz and Scandinavian music his work travels far beyond traditional boundaries. He's become more like a cross between a sound artist and a shaman. Isungset crafts his own instruments from natural elements found in Norway such as arctic birch, granite, slate, and even ice. In this interview from in front of the Canada Glacier in Antarctica’s Taylor Valley, Hassan Basagic from Portland State University describes the essential role of polar glaciers in supporting the bare-bones ecosystems in the Dry Valleys. The POLENET project installed their newest high-precision GPS system on Deverall Island, Antarctica. These GPS systems tell scientists how much the ground underneath the ice sheet is moving upward. This has important implications on the movement of the West Antarctic Ice Sheet and its interplay with the rock below. Learn more about it in this audio report from correspondent Kelly Carroll.
