Physical Science · California Grade 8
MS-PS4-2
Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
Clarification statement: Emphasis is on both light and mechanical waves. Examples of models could include drawings, simulations, and written descriptions.
Assessment boundary: Assessment is limited to qualitative applications pertaining to light and mechanical waves.
Chapters
Lab 3 and W9 use the idea that materials reflect, absorb or transmit sound to plan and explain noise shields. MS-PS4-2 is a Grade 8 performance expectation in the California integrated sequence; here it is used qualitatively as background and is not assessed.
