FWU - Schallwellen und Schallquellen

Wherever we go, we are surrounded by sounds; we live in an 'acoustic' world. Sound is everywhere. But what is sound, and how is it created? How does it reach our ears? And how can it be described? What are its properties? This educational DVD explores these questions in an entertaining way, using everyday examples. The DVD's ROM section includes worksheets, an interactive activity, teaching notes, and other supplementary materials. http://www.fwu-shop.de/schallwellen-u...
