Waves and Their Applications in Technologies for Information Transfer


Students who demonstrate understanding can:



Generate and compare multiple solutions that use patterns to transfer information. 4-PS4-3

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of solutions could include drums sending coded information through sound waves, using a grid of 1’s and 0’s representing black and white to send information about a picture, and using Morse code to send text.

Assessment Boundary: none

Science and Engineering Practices

Constructing Explanations and Designing Solutions

Constructing explanations and designing solutions in 3–5 builds on K–2 experiences and progresses to the use of evidence in constructing explanations that specify variables that describe and predict phenomena and in designing multiple solutions to design problems.

Generate and compare multiple solutions to a problem based on how well they meet the criteria and constraints of the design solution. (4-PS4-3)

Crosscutting Concepts


Similarities and differences in patterns can be used to sort and classify designed products. (4-PS4-3)

Connections to Engineering, Technology, and Applications of Science

Interdependence of Science, Engineering, and Technology

Knowledge of relevant scientific concepts and research findings is important in engineering. (4-PS4-3)

Common Core State Standards Connections

  • RI.4.1 - Refer to details and examples in a text when explaining what the text says explicitly and when drawing inferences from the text. (4-PS4-3)
  • RI.4.9 - Integrate information from two texts on the same topic in order to write or speak about the subject knowledgeably. (4-PS4-3)
