This resource, vetted by NSTA curators, is provided to teachers along with suggested modifications to make it more in line with the vision of the NGSS. While not considered to be “fully aligned,” the resources and expert recommendations provide teachers with concrete examples and expert guidance using the EQuIP rubric to adapted existing resources.

## Description

The Bite Size Physics website uses humor and simple hands-on activities to teach physics principles. This lesson gives a background lesson on waves, followed by several simple experiments to teach transverse and longitudinal waves, frequency, wavelength, and amplitude. The activities use only a rope, a slinky and colored tape to teach the concept, so they would be easy for the classroom teacher to reproduce for his or her students.

#### Performance Expectations

4-PS4-1 Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

Clarification Statement: Examples of models could include diagrams, analogies, and physical models using wire to illustrate wavelength and amplitude of waves.

Assessment Boundary: Assessment does not include interference effects, electromagnetic waves, non-periodic waves, or quantitative models of amplitude and wavelength.

This resource is explicitly designed to build towards this performance expectation.

This lesson includes information about transverse and longitudinal waves, which should be omitted at this grade level.

#### Science and Engineering Practices

This resource is explicitly designed to build towards this science and engineering practice.

As you are making the model of the wave, discuss the fact that this is a model of a wave and not the real thing. Discuss why we would use a model instead of a real wave (Example: the ocean is too big to fit into the classroom) and the limitations of the model (Example: if the two students do not work together, a wave will not be created). Remind students that waves can be found in sound and in light, also, and that they follow this same wave pattern.

#### Disciplinary Core Ideas

This resource is explicitly designed to build towards this disciplinary core idea.

The information at the end of Experiment #2 gives very good explanations for how amplitude determines the energy in an ocean wave, the loudness of a sound, or the brightness of a light. The teacher could introduce this same type of comparison relating wavelength to ocean waves, sound and light to bring it all together after Experiment #3.

#### Crosscutting Concepts

This resource was not designed to build towards this crosscutting concept, but can be used to build towards it using the suggestions provided below.
