Thursday's Learning Challenge

So today we watched Sid the Science Kid, my kids love this show, and they talked about sound waves. The kids loved it so today we are discovering difference sound waves. Whispering, talking normally, speaking through a megaphone (a little plastic toy one, thankfully), tapping different things, playing the game telephone to show how you have to listen to sound waves to know what you heard, and listing different things that make sounds. How do you teach your children about sounds?
