Instructional Ideas

• Review longitudinal and transverse waves by making them with a Slinky

Classroom Considerations

• Assumes the class has a basic understanding of the terminology associated with waves
• Requires use of a computer-based program from PhET Interactive Simulations

Pros

• Includes a list of terminology for the lesson
• Contains suggestions for extensions

Cons

• None
