Exploration of functions of the eye.

LS.2.K.5, Name and describe the five senses: sight
LS.2.6.4 Model and explain the function of organs: the eye.
LS.2.7.1 to LS.2.7.4, LS.2.7.8Analayze how two systems work together eye and brain. analyze organs using disection,
LS.2.7.6 to ,LS.3.8.13,LS.3.8.16 Identify basic ideas of evolution.

Finding Rays, Look at a small bright source of light, notice the rays around it, do experiments to find where these rays are located.
LS.2.6.4 The outer surface of the eye bends, refracts, and scatters light.
P.7.PS.2 Diffraction, linear imperfections in the cornea diffract light into lines on the retina perpendicuar to the imperfection.

See Your Pupil, Look at your pupil in a mirror, watch it change when someone shines a light into your eye.
LS.2. 6.4 Model and explain the function of organs: the eye.

Pin and Hole, Look at the world through a pinhole, notice it is right side up, look at a pin inside a film can and notice it is right side up. Your eye inverts images of distant objects but not of nearby objects.
LS.2.6.4, WO.10.P.8, WO.10.P.9, P.7.PS.11

Floaters, Look at a blue sky and see points and lines moving in your field of view, these are called floaters.
LS.2.6.4, PS.7.1.2, PS.7.2.1

Seeing Your Retina, Move a point of light back and forth in front of your eye while looking at a blank screen to see the blood network of your retina.
