4-PS4-1 Waves and Their Applications in Technologies for Information Transfer

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.

SEP: Construct explanations and Design Solutions:  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.

DCI: PS4A 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. (Note: This grade band endpoint was moved from K–2.)  Waves of the same type can differ in amplitude (height of the wave) and wavelength (spacing between wave peaks).

CC: Patterns:  Similarities and differences in patterns can be used to sort, classify, and analyze simple rates of change for natural phenomena.
