What Is Sound? for Kids

How exactly does sound work? If a tree falls in a forest but no one is around to hear it, does it make a sound? In this video, you and your kids will be able to answer both those questions. There are sounds all around us. Sound is made from vibrations, which are a series of small, fast movements that move back and forth or from side to side. Even our voices create sound because our vocal cords move from side to side. We can feel it whenever we put our hands on our throats and hum. When an object vibrates, it causes movement in the surrounding air particles. Those particles bump into other particles, making them vibrate too. This process continue until the particles run out of energy. This movement is called sound waves. Sound waves are what help vibrations travel. Whenever we are close enough to an object's vibrations, the sound waves it creates will reach our ear. Have you ever heard of pitch and volume? Pitch has to do with the highness or lowness of a sound. Faster vibrations yield a higher pitch while slower vibrations yield a lower pitch. Volume, on the other hand, measures the loudness or quietness of sound. This is also called its intensity or power. The higher a sound's intensity, the higher its volume.
