What is sound
People hear sound all day long. But not when you are sleeping!! We communicate with sound and rely on it. Sounds can warn us or tell us if something is dangerous or not. Especially animals rely on sound such as dolphins which mostly swim in the deep blue ocean. Dolphins can hear sounds that come from far, far away.
If you would like to draw a picture of sound
it could look like this …
One person talking to the other and one listening. The semicircular (half a circle) lines in the air represent sound waves like ripples in a pond!
Sound needs air, gas, or water. This is known as a medium.
Did you know that sound can’t travel through outer space because the vacuum doesn’t contain any medium to carry sound.
