Welcome to day four of Science Week! Yesterday we learned about heat, one of the forms of energy. Today we investigated another type of energy: sound. Sound is a form of energy that is made when an object vibrates. The bigger the vibrations, the louder the sound: like a thunder clap! The smaller the vibrations, the softer the sound: like the sound of a marker swiping across a piece of paper.
To experience sound, we made a simple musical instrument with a plastic bowl and some rubber bands.
|Carefully stretch a rubber band around a bowl or box.|

|Pour water into glass jars -- be sure to wipe up any spills!|
Sound is my favorite form of energy. Some of my favorite sounds are: songbirds, babies babbling, and the footsteps of those I love. What are your favorite sounds?
