Question of the Day : Question of the Day Which kind of wave describes how sound travels? What causes a sound wave? Question of the Day : Question of the Day Do air particles move with the sound wave? Slide 4: KWL What we already KNOW… : What we already KNOW… Sound can bend, or diffract, around a barrier. Sound bends around the corner of a doorway Sound can travel through solids, liquids, and gases. Slide 6: What do you want to know? Does sound travel through solids? : Does sound travel through solids? Paper Bag Plastic Can Metal Can Can sound travel through liquids? : Can sound travel through liquids? In your group, have one person tap the ends of the spoon under the water and the other person hold their ear against the beaker. Make sure you cover the ear that is not against the beaker. Switch places… and try again! Sound can travel through solids, liquids, and gases… : Sound can travel through solids, liquids, and gases… In which state of matter will sound travel fastest through? Activity What state of matter does sound travel best through? : What state of matter does sound travel best through? Hold the plastic bag of water against one ear. Cover your other ear with your hand. Listen to the sound on the outside of the bag. Remove the bag and listen. Place the solid between the sound and your ear. Do you hear the clock best through solids, liquids, or gases? Sound travels through solids the fastest… : Sound travels through solids the fastest… gases the slowest. Fastest Slowest Speed of Sound : Speed of Sound Speed of sound in each state of matter depends on 3 properties. Speed of Sound : Speed of Sound Remember the marble activity? Since sound is a transfer of energy… The speed of sound depends on how well the particles in the medium can move. Factors that affect the speed of sound: : Factors that affect the speed of sound: Elasticity ability of a material to bounce back (stretchy) In each state of matter, sound travels faster in more elastic materials Speed of Sound : Speed of Sound Density In each state of matter, sound travels slower in more dense materials. Speed of Sound : Speed of Sound Temperature In each state of matter, sound travels slower at lower temperatures and faster at higher temperatures.
