Science of Sound
What is sound? Sound is created when an object vibrates. The vibrations travel in waves. Sound waves reach our ears. The ears send a message to the brain. That’s how we hear different sounds! A sound can be loud or quiet. It can have a high pitch or a low pitch. Here are a few different sounds.
A drum can make a low-pitched rumbling sound. Thump thump!
Some birds make a high-pitched chirping sound. Tweet tweet!
A bee makes a quiet buzzing sound. Bzzzzz!
This alarm clock makes a loud ringing sound. Brrring!
