Every day we hear many different sounds around us. A sound is made when something is moving. In this lesson plan your class will need to listen carefully to hear what is making the sound, is it a loud sound or a soft sound, is it close or far away and record the sound when they hear it. Your class will then learn about three ways sound can be produced, vibrations, explosions, and flow of air. Measuring sound, uses of sounds, noise pollution, and characteristics of sounds will be discussed in this component. Answer key included.
