This high school lesson plan is intended to supplement the "Wave on a String" PhET simulation. Students apply the concepts introduced in the computer simulation to explore properties of sinusoidal functions. They will find an equation of a wave with pre-set components and analyze how amplitude, frequency, and tension influence changes in the wave motion. The activity is intended to take ~60 minutes to complete.
The wave simulation, which must be open and displayed to complete this activity, is available from PhET at: Wave on a String.
This lesson is part of PhET (Physics Education Technology Project), a large collection of free interactive simulations for science education.

4. The Physical Setting
6-8: 4F/M4. Vibrations in materials set up wavelike disturbances that spread away from the source. Sound and earthquake waves are examples. These and other waves move at different speeds in different materials.
6-8: 4F/M7. Wave behavior can be described in terms of how fast the disturbance spreads, and in terms of the distance between successive peaks of the disturbance (the wavelength).
9-12: 4F/H6ab. Waves can superpose on one another, bend around corners, reflect off surfaces, be absorbed by materials they enter, and change direction when entering a new material. All these effects vary with wavelength.
9. The Mathematical World
9B. Symbolic Relationships
9-12: 9B/H5. When a relationship is represented in symbols, numbers can be substituted for all but one of the symbols and the possible value of the remaining symbol computed. Sometimes the relationship may be satisfied by one value, sometimes by more than one, and sometimes not at all.
11. Common Themes
6-8: 11B/M4. Simulations are often useful in modeling events and processes.
9-12: 11B/H1a. A mathematical model uses rules and relationships to describe and predict objects and events in the real world.

Expressions and Equations (6-8)
Represent and analyze quantitative relationships between
dependent and independent variables. (6)
6.EE.9 Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

Topic: Periodic and Simple Harmonic Motion Unit Title: Simple Harmonic Motion
This high-quality lesson plan was created to be used with the PhET simulation "Wave on a String". Students will apply the concepts introduced in the computer simulation to explore frequency, amplitude, and tension on an oscillating string. Editor's Note: this lesson gives students the chance to model the movement of energy on a string by applying properties of sinusoidal function. A great integration of trigonometry and physics.....and it's fun!
Topic: Wave Energy Unit Title: Wave Properties: Frequency, Amplitude, Period, Phase
This is a computer lab created specifically for use with the PhET simulation "Wave on a String" (see Activities below). Students apply trigonometry and analyze how frequency, amplitude, and tension influence the motion of the wave. It may be downloaded as a Word file.
