In middle school, students develop an understanding of the disciplinary core ideas in the physical science domain. The middle school performance expectations build on the elementary performance expectations and allow students to explain concepts that are important not only to physical science, but also to life science and the earth and space sciences. In PS4: Waves and Their Applications in Technologies for Information Transfer, performance expectations allow students to demonstrate an understanding of wave properties and behaviors of and the use of waves to send digital information.

 

In high school, students continue to develop and refine their understanding of physical science concepts. The high school performance expectations are meant to expand on the middle school performance expectations. The high school performance expectations cover fundamental concepts of chemistry and physics, while leaving room for more expanded and in-depth study in upper level high school courses. As in middle school, physical sciences concepts are also important for understanding life and Earth and space sciences. Performance expectations in high school PS4: Waves and Their Applications in Technologies for Information Transfer require students to demonstrate an understanding of how waves transfer energy and send and store information. By the end of high school, students should be able to demonstrate a quantitative understanding of physical and electromagnetic waves through a variety of models.

 

PS4: Waves and Their Applications in Technologies for Information Transfer

Middle School

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.

MS-PS4-2 Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

 

PS4: Waves and Their Applications in Technologies for Information Transfer

High School

HS-PS4-1 Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.

HS-PS4-3 Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model, and that for some situations one model is more useful than the other.

HS-PS4-4 Evaluate the validity and reliability of claims in published materials of the effects that different frequencies of electromagnetic radiation have when absorbed by matter.
