Curricular Unit: Waves: The Three Color Mystery

Contributed by: Research Experience for Teachers (RET) Program, Center of Advancement of Engineering Fibers and Films, Clemson University

Summary

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five lessons designed to teach wave properties, the electromagnetic spectrum, and the anatomy of the human eye in an interactive format that introduces engineering applications and real-world references. It culminates with an activity in which student teams apply what they have learned to design devices that can aid people with colorblindness in distinguishing colors— as evidenced by their creation of brainstorming posters, descriptive brochures and short team presentations, as if they were engineers reporting to clients. Through this unit, students become more aware of the connections between the biology of the eye and the physical science concept of light, and gain an understanding of how those scientific concepts relate to the field of engineering.


Engineering Connection

Engineers use the properties of waves in the design of everyday tools. Rearview mirrors, x-ray machines, and microwaves are examples of technologies that rely on an understanding of waves. When engineers work with ophthalmologists and optometrists to design eyeglasses, as another example, they apply their knowledge of light waves to the interactions light has with human eyes, so that they can customize solutions for individual deficiencies. Engineers of all disciplines employ the steps of the engineering design process in order to create innovative, effective and efficient solutions to human challenges.
