Resources to Address This

  • How do we see?  (5-11)

    Ref- SPT HS01 TL02

    Right Lines:You are able to see as a result of light entering your eye. Light may come directly from a luminous source, or reflect off an object, or be scattered from particles and then enter the eye.

    This activity challenges the ideas of a pool of light; an active eye; light from eye to object.
