If a tree falls in the woods and no one is there to hear it, does it make a sound? That all depends on what sound actually is! Cheryl has some ideas and learns more about what sound is, how we hear, and how sound is connected to light. How much do you know about sound? It&#39;s never too late to learn about the world around you.

This is part of the Invisible Things unit.
