Description

From TeachEngineering - Students examine the existence of sound by listening to and seeing sound waves while conducting a set of simple activities as a class or in pairs at stations. Students describe sound in terms of its pitch, volume and frequency. They use this knowledge to discuss how engineers study sound waves to help people who cannot hear or talk.

Performance Expectations

4-PS4-1   Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.
