Acerca de este recurso...

Sound travels in waves, similar to light. If you shine a light onto a mirror the light bounces off the mirror so that the light shines in a different direction. The same is true for sound. Sound waves can reflect off of surfaces, redirecting the waves creating an echo. A gymnasium is a good example of how echoes are produced. The room is large with six hard surfaces, the four walls, floor, and ceiling. A few seconds after you yell you can hear it again because the sound waves bounced off of the six surfaces and back to your ear. In this experiment students will create echoes by yelling in spaces, such as an empty room, gymnasium, and bedroom. Students will explore how sound waves are reflected and absorbed by producing echoes.
