Description
Presenting fact through fantasy, this video introduces students to basic concepts of sound. Two children and a one-of-a-kind genie travel through time and space to experience the various aspects of sound. The genie shows them that sound is actually invisible waves traveling through air, water, or materials. He demonstrates how sound waves travel outward from their source, like ripples on a lake. He explains the phenomenon of echoes, and the difference between loud and soft sounds. He also demonstrates how sounds are produced through vibrations and how different pitches are produced. Solid information and entertaining.
