The Oklahoma Academic Standards for Science (OAS-S) are three-dimensional performance expectations representing the things students should know, understand, and be able to do to be proficient in science and engineering. Performance expectations are considered standards and include a science and engineering practice (indicated in blue and represent everyday skills of scientists and engineers), disciplinary core ideas (represented in orange and represent science ideas used by scientists and engineers), and a crosscutting concept (indicated in green and represent ways of thinking like scientists and engineers).

Each dimension in the OAS-S grows in complexity and sophistication across the grades. To learn more about the prior knowledge and skills students have developed (or future knowledge/skills) associated with that specific dimension, each section in the standard below is hyperlinked to that specific vertical learning progression page.

Physics (PH) Waves and Their Applications in Technologies for Information Transfer
PH.PS4.1 Use mathematical representations to explain both qualitative and quantitative relationships among the frequency, wavelength, and speed of waves traveling in various media.
Clarification Statement: Emphasis is on using mathematical relationships to understand how various media change the speed of waves. Examples of different media that could be explored include electromagnetic radiation traveling in a vacuum or glass, sound waves traveling through air or water, or seismic waves traveling through Earth.
Assessment Boundary: Assessment is limited to algebraic relationships and describing those relationships qualitatively.
Science and Engineering Practices	Disciplinary Core Ideas	Crosscutting Concepts
Using Mathematics and Computational Thinking Use mathematical, computational, and/or algorithmic representations of phenomena or design solutions to describe and/or support claims and/or explanations.	Wave Properties 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.	Cause and Effect Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
