SOUND VIBRATIONS CAN TRAVEL THROUGH
- solid metal, wood and concrete
- sound can vibrate through water and liquids
sound can travel by instruments by a low and high pitch
did you hear something? maybe
the sound you heard was as quiet as
your cat licking her paws.Or maybe
it was loud, like a siren going by.
sounds are everywhere ,and you
have two cool parts on your body
that let you hear them all:
your ears are in charge of collecting sounds,
processing them, and sending sound signals to
your brain.And thats not all- your ears also help
you to keep balance. So if you bend over to pick
up your cat, you won’t fall down -or even worse-
fall on your cat. MEOW !
sounds are made when a objects vibrate.
the vibrations makes the air around
vibrate, and the air vibrations enter
your ear .you hear them…
