Vision: First & Third GradesKey Concepts:
1. How the nervous system controls vision.
2. How insults to the nervous system and eye cause impairment to vision.
3. Ways to protect the nervous system and the eye from environmental hazards.
4. Understanding of and tolerance toward individuals with visual disabilities.Core Curriculum:
A) Scientific Inquiry
Through scientific inquiry students will learn:
• The anatomical parts and function of the eye through the use of interactive eye models. They will become familiar with how a healthy eye functions and how glasses can correct for nearsightedness, farsightedness, presbyopia, and astigmatisms.
• The structure and function of the retina, physical and genetic determinants of color vision, and the effects of retinal damage due to trauma. They will also learn about their blind spot, the portion of the retina where no image forms due the terminus of the optic nerve.
• To protect their eyes from environmental contributors to visual impairment.
• The complex interaction between the brain and the eye. They will investigate differences in perception through the use of optical illusions and Stroop tests, persistence of vision, and peripheral vision.
• How the senses work together, and how the loss of one sense may amplify the other senses.
B) Simulations - Experiential Inquiry
Students will learn about visual impairment through simulations including learning how to assist a visually impaired person, Braille and the Braille alphabet, and using tools visually impaired people use to function in a world designed for people who see. They will attempt a variety of tasks while blindfolded, including putting on clothing, identifying objects, shopping, and using money. Students will also learn about common visual impairments other than blindness such as Hyperopia, and Myopia, and about disease and damage which can occur in different parts of the visual system such as Macular Degeneration, Cataract, and Glaucoma.
C) Community Ambassador
Students will have an open-ended discussion with a disabled individual. They will learn about the challenges they face as a result of their disability with emphasis on previous lessons.
