My Sound Explanation

For inquiry this term we are studying sound this explanation will explain what sound is.
Sound is a vibration that travels really fast when you hit it or make some kind of noise. Where there is nothing not even air there is no sound so sound will not travel past or through because there will be no vibration to send sound waves .

Have you ever wonder where sound comes from? If you hit the table you hear a bang that comes from vibration. When you bang the table it moves really fast to cause sound to happen. It is not all about how sound is made when you bang the table that sound travels in sound waves that hit your eardrums it vibrates and moves into your ear and that takes it to the brain and what your brain does is it will translate that sound which you may or not know already.

Vibration moves really really fast to the back and front. Everywhere you go sound is around all of us, you can hear people talking, birds chirping, plane engines and many more. Even if you think you are in a silent room there is still noise even if you can't hear it. There are different sounds where you go some may be high and some may be low. You can like sound more than others and some sounds not too much. Do you have a sound you don't like?

Some sounds can be really noisy and some can be quite. Different things send out different sound waves. The sound waves vibrate at different rates, the pitch of the sound count on the number of vibrations per second. More vibration there are per second the higher the sound. Some sound don't vibrate with enough energy to make a sound. And some sound have so much energy they can hurt our ear, the more energy it has the louder the sound.

How could we live without sound there will be t.v with no sound how boring is that. Or if we want to listen to music there will be no sound. I can't imagine the world without sound. In our class we tried out phone cups its easy to make. It was really cool too. What you need to do get is plastic cups and a string, poke a hole in the cup and put the string though the cup. Get a ice block stick and cut it up into small pieces and when you put the string through the hole get the ice block stick and tie it on to the string so it doesn't come off make sure the string is tight so you can hear the other person . Have fun.
