Slinkys+and+Sine+Graphs

Explanation
This lesson allows students to explore trigonometric functions using a household slinky, a graphing calculator and a CBR unit. Students formulate their own slinky sine equations and then compare and contrast their group's equations with the rest of the class. Students use their equation to identify the following components of a sine graph, amplitude, period, phase shift and vertical displacement. Finally, this lesson concludes with students identifying real world examples of sine waves.

Teaching
Lee (2005) created this lesson called name that frequency. [|www.ms.uky.edu/~lee/amspalg05/ASlinkyGraph.doc]  This s a document that contains the worksheet information that we used, though, it uses a different software program.
