Performance expectationUse mathematical representations to support a claim regarding relationships among the period, frequency, wavelength, and speed of waves traveling and transferring energy (amplitude, frequency) in various media.
Examples of data could include descriptions of waves classified as transverse, longitudinal, mechanical, or standing, electromagnetic radiation traveling in a vacuum and glass, sound waves traveling through air and water, seismic waves traveling through Earth, and direction of waves due to reflection and refraction.
Assessment is limited to algebraic relationships and describing those relationships qualitatively.
Every item written to HS-PS4-1 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
