Copyright © 2012 InteractiveScienceLessons.com Do: Pushed and pulled on a slinky. See: As the energy moved through, it squeezed and compressed the bands. What’s Happening: Sound waves are very fast ripples of energy that squeeze matter without moving it. They are appropriately named compression waves. Interactive Notes: Sound Read p. ¶ together
Copyright © 2012 InteractiveScienceLessons.com Do: Tapped on a metal hanger by itself, and then on a foam block. See: The foam amplified it, and made it sound like a church bell! What’s Happening: The foam has more surface area, so more air touches it. And since air conducts sound, it can conduct more sound. The best conductors of sound are: 1. solid (best) 2. liquid 3. gas (worst) Read p. ¶ together
Copyright © 2012 InteractiveScienceLessons.com Do: Shook water inside a flask with and without air. See: Without air there was no sound. What’s Happening: Sound cannot travel through empty space because it must have something to compress to be able to travel. So, does an exploding star make a sound? Does light travel through empty space?
Copyright © 2012 InteractiveScienceLessons.com Do: Struck a small and a large tuning fork. See: The smaller fork was higher pitched. What’s Happening: Pitch is the highness or lowness of a sound. Frequency is how many waves pass a point per second. The more waves, the _____ the pitch, and fewer waves= ____ pitch. 125 Hz- means 125 waves pass by your ear every second 1000 Hz higher lower
