The Science of Sound

This afternoon our class investigated the sounds that are natural, man made, used for communication and music.  We looked at lots of different things that made sounds that our classmates had brought from home.  There was a big fishing reel that clicked when you wound the handle, a door bell, a flute, an iPod Touch, a mobile phone, an iPad, a clock and a clock radio, a harmonica, a DSi, a whistle, a timer and some other things.  We found that we use our voices to communicate and that there are lots of different sounds in our daily lives like brids chirping, cars, radios, leaves rustling and many others.  Sound is very important to us and it helps us to learn.
