Waves and Their Applications in Technologies for Information Transfer

 

Students who demonstrate understanding can:

Performance Expectations
 

 

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

Clarification Statement and Assessment Boundary

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.

Science and Engineering Practices

Developing and Using Models

Modeling in 3–5 builds on K–2 experiences and progresses to building and revising simple models and using models to represent events and design solutions.

Develop a model using an analogy, example, or abstract representation to describe a scientific principle. (4-PS4-1)

Connections to Nature of Science

Science Knowledge Is Based on Empirical Evidence

Science findings are based on recognizing patterns. (4-PS4-1)

Disciplinary Core Ideas

PS4.A:  Wave Properties

Waves, which are regular patterns of motion, can be made in water by disturbing the surface. When waves move across the surface of deep water, the water goes up and down in place; there is no net motion in the direction of the wave except when the water meets a beach. (4-PS4-1)

Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks). (4-PS4-1)

Crosscutting Concepts

Patterns

Similarities and differences in patterns can be used to sort and classify natural phenomena. (4-PS4-1)
