MS-PS4-1 - Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.

Clarification Statement - Emphasis is on describing waves with both qualitative and quantitative thinking.

Assessment Boundary - Assessment does not include electromagnetic waves and is limited to standard repeating waves.

6.MS-PS4-1 - Use diagrams of a simple wave to explain that (a) a wave has a repeating pattern with a specific amplitude, frequency, and wavelength, and (b) the amplitude of a wave is related to the energy of the wave.

Assessment Boundary - Electromagnetic waves are not expected in state assessment. •State assessment will be limited to standard repeating waves.
