Comments about Including the Performance Expectation
This full unit addresses this performance expectation in full, as well as provides background knowledge for teachers prior to teaching the unit.
This unit addresses the full performance expecations using the 5-E unit model. In the Engage phase, students make observations about sound in their environment, asking questions about a teacher- led activity involving a salt drum. In the Explore phase, students are able to make the connection between sound, vibration and matter by visiting 8 "sound centers" where they observe the way various objects make sounds by interacting with the materials. They conduct investations at each of these centers. In the Explain phase, media is introducted to help explain the phenomena they encountered in the prior lesson as well as a slink demonstration to model waves. Using all they have learned, students then create an make a tin-can telephones in the Elaborate phase. Finally, in the evaluate phase, they are provided a variety of materials used in prior lessons to make an authenitc model that is able to communicate over a distance.
