Subject: Mathematics (9 - 12)
Title: "Woody Sine"
Description: The students will discover the shape of the sine function without creating a t-chart. The students will create a sine function using toothpicks. The students will then discover how the amplitude (height) and the period (number of compete waves) change when the basic graph created from the broken tooth picks was changed. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Title: Technology for Displaying Trigonometric Graph Behavior: Sine and Cosine
Description: After interacting with a list of specified websites, students will explain the effects of various coefficients on the graphs of sine and cosine by describing these effects on a lab activity worksheet with an accuracy of 80%.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

Graphs From the Unit Circle
http://illuminations...
In this lesson, students use uncooked spaghetti to transfer lengths from the unit circle to a function graph on large butcher paper. In the process, they discover the key features of sine and cosine graphs. The activity is presented for students working in degrees, but another version of the handouts is provided for students working in radians.

Sine Function (with Unit Circle)
http://www.desmos.co...
This is an interactive model of the graph of a sine wave in the form y=sin(b). There is a slider that allows the value of "b" (in radian measure) to be changed. The unit circle is shown simultaneously with the graph of the sine function.
