Developing and Using Models

Crosscutting Concepts

Cause and Effect

Knowledge

Students know:
  • Light enters the eye, allowing objects to be seen.
  • Light reflects off of objects, and then can travel and enter the eye.
  • Objects can be seen only if light follows a path between a light source, the object, and the eye.

Skills

Students are able to:
  • Construct a model to make sense of a phenomenon.
  • Identify relevant components of the model including: light (including the light source), objects, the path that light follows, and the eye.

Understanding

Students understand that:
  • An object can be seen when light reflected from its surface enters the eyes.

Vocabulary

  • reflection
  • opaque
  • translucent
