The Standards

4th Grade

Waves and Their Applications in Technologies for Information Transfer

Students who demonstrate understanding can:



Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen. 4-PS4-2

Clarification Statement and Assessment Boundary

Clarification Statement: none

Assessment Boundary: Assessment does not include knowledge of specific colors reflected and seen, the cellular mechanisms of vision, or how the retina works.

Science and Engineering Practices

Developing and Using Models

Modeling in 3–5 builds on K–2 experiences and progresses to building and revising simple models and using models to represent events and design solutions.

Develop a model to describe phenomena. (4-PS4-2)

Disciplinary Core Ideas

PS4.BElectromagnetic Radiation

An object can be seen when light reflected from its surface enters the eyes. (4-PS4-2)

Common Core State Standards Connections

  • SL.4.5 - Add audio recordings and visual displays to presentations when appropriate to enhance the development of main ideas or themes. (4-PS4-2)
  • 4.G.A.1 - Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures. (4-PS4-2)
  • MP.4 - Model with mathematics. (4-PS4-2)
