Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen. 4-PS4-2
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.
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)
PS4.B: Electromagnetic Radiation
An object can be seen when light reflected from its surface enters the eyes. (4-PS4-2)
Cause and Effect
Cause and effect relationships are routinely identified. (4-PS4-2)
