Waves and Their Applications in Technologies for Information Transfer


Students who demonstrate understanding can:



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-PS4-1

Clarification Statement and Assessment Boundary

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.

Science and Engineering Practices

Using Mathematics and Computational Thinking

Mathematical and computational thinking at the 6–8 level builds on K–5 experiences and progresses to identifying patterns in large data sets and using mathematical concepts to support explanations and arguments.

Use mathematical representations to describe and/or support scientific conclusions and design solutions. (MS-PS4-1)

Connections to Nature of Science

Science Knowledge Is Based on Empirical Evidence

Science knowledge is based upon logical and conceptual connections between evidence and explanations. (MS-PS4-1)

Common Core State Standards Connections

  • SL.8.5 - Integrate multimedia and visual displays into presentations to clarify information, strengthen claims and evidence, and add interest. (MS-PS4-1)
  • 6.RP.A.1 - Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. (MS-PS4-1)
  • 6.RP.A.3 - Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. (MS-PS4-1)
  • 7.RP.A.2 - Recognize and represent proportional relationships between quantities. (MS-PS4-1)
  • 8.F.A.3 - Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. (MS-PS4-1)
  • MP.2 - Reason abstractly and quantitatively. (MS-PS4-1)
