But think back to our original engineering challenge about color blindness. So far, we have been learning all about waves and light. The slides are "animated" so you can click to show the next item when ready.) Also, prepare to show students the attached 11-slide Eye Structure and Seeing Light Presentation to accompany the lesson introduction.
(In advance, make copies of the Eye Structure and Seeing Light-Notes Outline, In and Out of Focus Worksheet and Eye Anatomy Quiz, one each per student. Identify components that make up the eye.Įye Anatomy Quiz Answers (pdf) Visit [ to print or download.This step is a crucial part of the engineering design process.Īfter this lesson, students should be able to: Before designing solutions to problems, engineers must conduct research and gather information. Through this legacy cycle lesson, students continue to gather the knowledge necessary to come up with a solution to the engineering challenge outlined in Lesson 1 of this unit. To do this, they must thoroughly understand eye anatomy and function. They also design tests and diagnostic equipment used to evaluate and investigate health conditions. These topics help students prepare to design solutions to an overarching engineering challenge question.Įngineers design devices to help people with vision deficiencies. During their investigations, they test other students' vision, gathering data and measurements about when objects appear blurry. They conduct experiments as an example of research to gather information. Students learn about the anatomical structure of the human eye and how humans see light, as well as some causes of color blindness.
