Lesson Objectives Explain how light travels Explain how we see objects Know how shadows are formed.

How you See The eye & vision. How You See The eye collects light from objects and projects them on the light-sensitive portion of the eye, the retina.

The eye is an important sense organ. It takes light and images from the world around us and sends them as an electrical impulse to the brain. Parts: Cornea:

Receptors Receptors are part of the co-ordination system that detect the changes of the environment by means of stimuli. Two types... Interoceptors – receptors.

Year Science. Cornea Transparent outer covering of the eye It is convex in shape to allow the light that passes through it to be refracted Cornea.

Learning Objectives Can you label a diagram of the eye and explain the function of each part? How does the eye focus on near and distant objects, and respond.

The Human Eye. A convex lens is the type of lens found in your eye. The lens takes light rays spreading out from objects and focuses the light, through.

Learning Objective: To be able to describe the key parts of the eye and explain their functions. To also be able to evaluate whether seeing is as simple as using one sense. I can state some parts of the eye. (Grade C) I can explain what each key part of the eye does. (Grade B) I can evaluate whether our sight is or is not single sensory. (Grade A)
