# 4-PS4-2 Waves and Their Applications in Technologies for Information Transfer

4-PS4-2   Waves and Their Applications in Technologies for Information Transfer

Students who demonstrate understanding can:

4-PS4-2. Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen. [Assessment Boundary: Assessment does not include knowledge of specific colors reflected and seen, the cellular mechanisms of vision, or how the retina works.]
The performance expectation above was developed using the following elements from the NRC document A Framework for K-12 Science Education:

## 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.

## Crosscutting Concepts

### Cause and Effect

Connections to other DCIs in fourth grade: N/A

Common Core State Standards Connections:

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