This is a standards-aligned lesson plan for secondary education on the topic of mechanical wave motion. The lesson blends a six-minute video with a classroom activity that uses Slinky springs to model transverse and longitudinal waves. Explicit directions are given to support new or crossover teachers, including background information on wave energy and discussion questions.
This resource was developed for use with the video "Making Big Waves", which may be freely downloaded for classroom use.
PBS Learning Media is a growing collection of free educational resources compiled by researchers and experienced teachers to promote the use of digital resources in the classroom.

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.
9-12: 4F/H6c. The energy of waves (like any form of energy) can be changed into other forms of energy.
11. Common Themes
3-5: 11B/E4. Models are very useful for communicating ideas about objects, events, and processes. When using a model to communicate about something, it is important to keep in mind how it is different from the thing being modeled.
6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.
9-12: 11B/H5. The behavior of a physical model cannot ever be expected to represent the full-scale phenomenon with complete accuracy, not even in the limited set of characteristics being studied. The inappropriateness of a model may be related to differences between the model and what is being modeled.

Wave Properties (PS4.A)
A simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude. (6-8)
The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing. (9-12)

Topic: Wave Energy Unit Title: Types of Mechanical Waves
This lesson integrates a short video, "Making Big Waves", with a detailed lesson plan on using Slinky springs to model transverse and longitudinal waves. This web site gives teachers great support in the form of background information on wave energy, discussion questions, and tips for implementing the activity effectively.
