Closure

=Discussion questions to be answered in your science journal=
 * “What did you learn about afterimages by doing these experiments?”
 * “What is an afterimage?”
 * “When do we see afterimages?”
 * “Which part(s) of the eye is/are responsible for receiving information about an object’s color and sending it to the brain for interpretation?”

=I would like you to think about the following:= We have learned that cones are responsible for color and the nerve receptors fatigue very easily, do you think the rods in our eyes, which are the light receptors for bright and dark light also have a similar effect where they fatigue? How can we test this?
