Sound

What is sound? What is pitch? These are the big questions we explored. Students found that sound is made from vibrations! When you play a musical instrument, it makes the **air ** around you __**vibrate** __ ( **move back and forth rapidly **). The air carries the __**vibrations** __ to your ears and your **eardrums vibrate ** so that you can hear the sounds. We f ound that sound also has different pitches... sounds can be high or low. We explored ways to change the pitch of sound!
