In science we are looking at sound. This afternoon we were exploring how sound can change over a distance. As part of this we created string telephones to demonstrate how sound travels. We discovered that we could hear clearly through the cups as the string and the cups are solid, so the particles are much closer together than the particles in the air, which is a gas. The sound energy can travel from particle to particle far easier in the solid string telephone, so the sound of our voices were louder over the same distance than it was in the air. We had a great time discovering how sound travels over distance!
