Every sound we hear can be discriminated against another sound. For example, the sound a washer makes sounds quite differently than the sound a popsicle stick makes.
Knowing that sound can be used to communicate, third graders are using sound to "tell" a code. Using their drop chambers and some everyday objects, they are trying to have their friends guess their secret message. Their sound code is one example of a code. We discussed how braille, sign language, and music are special codes, too!
