This lesson plan aims to introduce 7th grade students to basic anatomy of the eye. Sight is one of the senses that humans rely on the most, so understanding the basics of the visual system helps students understand where one of our most powerful senses originates. This lesson will introduce students to the structures of the eye that bend light (cornea, lens), control light (iris, pupil), and process light (retina). Furthermore, students will learn how light signals are sent to the brain (optic nerve) in order to perceive light as vision. A hands-on activity of building their own eye will reinforce student learning.
