Students trace the path of light from a source, off an object and into the eye, learn the jobs of the cornea, pupil, iris, lens, retina and optic nerve, explain why we cannot see in total darkness, and observe how the pupil changes in bright and dim light.

Read the passage. Then circle the best answer.
We see when light enters our eyes. Light comes from a light source, such as the Sun or a lamp. Most objects do not make light; we see them because light reflects off them and travels in straight lines into our eyes.
Light passes through the clear cornea at the front of the eye, then through the pupil — the black hole in the middle. The colored iris around the pupil changes its size: smaller in bright light, bigger in dim light.
Behind the pupil, the lens focuses the light onto the retina at the back of the eye. The image formed there is actually upside down! The retina sends signals along the optic nerve to the brain, which turns them into the picture we see the right way up.
In a completely dark room there is no light to reflect into our eyes, so we cannot see anything at all.
Write True or False.
