Sound Poem

Thanks to Mr. R.'s World of Math and Science we have found a poem that talks about what we have been learning in class about sound. We know that sound creates vibrations and this is how we hear. We also know that the higher the sound the faster the vibration and the closer together the sound waves become. Also the further away we are from the sound the longer it takes to travel to our ears. Our brain will sometimes see sound before we hear it, for instance in a storm we see the lightening before the thunder, that's because light travels faster than sound.

Sound

Clang!
Bang!
Boom!
Pound!

Things gotta' move,
To make a sound...
And that movement,
Makes vibration,

Makes a sound,
Celebration!
Vibrations come,
To our ear,
In a wave,
That we hear!

Vibrate fast,
Sound is high,
Vibrate slow,
Sound is low!
Clang,
Bang,
Boom,
Pound,
Things gotta' move,
To make a sound!

What is sound?
Sounds are made by vibrations that create waves (in air, water, etc.) When these waves are detected by our ears, we hear them as different sounds. When the vibrations are faster, the sounds have a higher pitch, and when they are slower, they have a lower pitch. When the vibrations are moving more (larger amplitude) the sound is louder, and when the vibrations are moving with a smaller amplitude, the sound is softer.
