Author Description

For science teachers and students in grades 5-9. Listen. What do you hear? Even if no one is around and your answer is "silence", you can be sure that sound waves are bouncing around you. You'll have to turn the page, close the book, or put it down at some point, right? Sound waves are all around us in the form of vibrations. A partnership between the brain, ear, and structures in between help us to interpret these vibrations as sounds. Yet there is also a whole world of sounds that we can't even hear. Other animals, however, may tune in on them. That's why a dog may pick up its head and look around, even though you don't see or hear anything. In VIBES, Discovery Channel takes you on ajourney through the hearing process and beyond. Learn how sound is produced and picked up by ears, what it's like to be unable to hear, how the amazing energy of sound waves can heal or harm, and more.
