Educational Use
Rating
0.0 stars

Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

Rating
0.0 stars

Students learn about the basic properties of light and how light interacts with objects. They are introduced to the additive and subtractive color systems, and the phenomena of refraction. Students further explore the differences between the additive and subtractive color systems via predictions, observations and analysis during three demonstrations. These topics help students gain a better understanding of how light is connected to color, bringing them closer to answering an overarching engineering challenge question.

The Three Color Mystery
Read the Fine Print
Educational Use
Rating
0.0 stars

Students are introduced to an engineering challenge in which they are given a job assignment to separate three types of apples. However, they are unable to see the color differences between the apples, and as a result, they must think as engineers to design devices that can be used to help them distinguish the apples from one another. Solving the challenge depends on an understanding of wave properties and the biology of sight. After being introduced to the challenge, students form ideas and brainstorm about what background knowledge is required to solve the challenge. A class discussion produces student ideas that can be grouped into broad subject categories: waves and wave properties, light and the electromagnetic spectrum, and the structure of the eye.

Understanding the Structure of the Eye
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn about the anatomical structure of the human eye and how humans see light, as well as some causes of color blindness. They conduct experiments as an example of research to gather information. During their investigations, they test other students' vision, gathering data and measurements about when objects appear blurry. These topics help students prepare to design solutions to an overarching engineering challenge question.

Waves Go Public!

Rating
0.0 stars

Students apply everything they have learned over the course of the associated lessons about waves, light properties, the electromagnetic spectrum, and the structure of the eye, by designing devices that can aid color blind people in distinguishing colors. Students learn about the engineering design process and develop three possible solutions to the engineering design challenge outlined in lesson 1 of this unit. They create posters to display their three design ideas and the comparisons used to select the best design. Then, students create brochures for their final design ideas, and "sell" the ideas to their "client." Through this activity, students complete the legacy cycle by "going public" with the creation of their informative posters and brochures that explain their designs, as well as color blindness and how people see color, in "client" presentations.

Waves: The Three Color Mystery
Read the Fine Print
Educational Use
Rating
0.0 stars

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.

Waves and Wave Properties
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn about the types of waves and how they change direction, as well as basic wave properties such as wavelength, frequency, amplitude and speed. During the presentation of lecture information on wave characteristics and properties, students take notes using a handout. Then they label wave parts on a worksheet diagram and draw their own waves with specified properties (crest, trough and wavelength). They also make observations about the waves they drew to determine which has the highest and the lowest frequency. With this knowledge, students better understand waves and are a step closer to understanding how humans see color.
