Dionne and Zoe are partners in science class. They have been asked to design a device that will communicate sound across a distance. Dionne thinks their device would work best if they used some kind of solid object to transfer the sound across a distance. Zoe, on the other hand, thinks their device would work better if it used the air to transfer the sound. Who is correct? Why?
