ALEX Lesson Plans


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.


Subject: Mathematics (9 - 12), or Technology Education (9 - 12)
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.

Subject: Mathematics,Science
Title: Sound Wave      Add Bookmark
Description: This student interactive, from Illuminations, helps students understand the mathematical models used to represent sound. Students come to understand the origins of the terms pitch, tone, frequency, and intensity, as well as explore the dynamics of a sound wave.
Thinkfinity Partner: Illuminations
Grade Span: 9,10,11,12



Subject: Mathematics,Science
Title: Do You Hear What I Hear?      Add Bookmark
Description: In this lesson, from Illuminations, students explore the dynamics of a sound wave. Students use an interactive Java applet to view the effects of changing the initial string displacement and the initial tension.

Subject: Mathematics
Title: Trigonometric Graphing      Add Bookmark
Description: This student interactive from Illuminations allows students to graph trigonometric functions. Parameters that affect the amplitude, period, and phase shift of the function can be manipulated.
