The importance of the brain in interpreting sensory information should be dealt with. The importance of protecting the senses is also covered.
Students learn what happens when the senses become damaged.
They recognize that damage to the senses may be permanent, requiring special ways to overcome the impairment. They also learn to empathize with those who are trying to overcome impairments. The Optional Unit on Vertebrates and Invertebrates can be related to this unit by examining ways that animals have adapted to interpret sensory information. Comparisons between human senses and the senses of other animals could be made. The Optional Unit, Light , could be used in conjunction with ideas developed relating to human vision, the eye, eye glasses, and so on.
