Summary
This lesson culminates the unit with the Go Public phase of the legacy cycle. In the associated activity, students depict a tumor amidst healthy body tissue using a Microsoft Excel® graph. In addition, students design a brochure for both patients and doctors advertising a new form of painless yet reliable breast cancer detection. Together, the inclass activity and the takehome assignment function as an assessment of what students have learned throughout the unit.Engineering Connection
As part of the engineering design process, when a need in society is established as an engineering challenge, in order for the challenge to be solved, the solution must be well tested, found to be reliable and then presented to the demographic in need, through evidential explanations. For example, in the case of biomedical engineering, a need for painless, reliable breast cancer detection has been presented to researchers at the university level. Following the engineering design process, once a welltested, consistent and accurate solution has been established in ultrasound technology, it must be presented to radiologists in hopes of implementation on a clinical level. Similarly, in the associated activity, students must demonstrate the accuracy of their solution; while in the lesson's assessment, students must present the solution to doctors and patients with an informative brochure.
PreReq Knowledge
A complete understanding of Hooke's law and stressstrain relationships.
Learning Objectives

 Present a painless means of detecting breast cancer.
 Explain how knowing the different properties of a material can lead to a useful solution.

Introduction/Motivation
Today is the big day! Today we will design a painless yet reliable method for detecting breast cancer. This is the time to Go Public with what you've learned! First you will complete the inclass portion in which you create a graph depicting the location of a tumor given certain conditions. Then you have three nights to complete the takehome portion in which you create a brochure advertising the new form of breast cancer detection to patients and doctors. Your brochure should explain how it works and the advantages and disadvantages of your design. It should also explain how you disseminated the problem and found a manageable solution to a complex issue. Please use the grading rubric to guide your brochure design.
Lesson Background and Concepts for Teachers
Legacy Cycle Information
This lesson includes the final step of the legacy cycle, the Go Public step. In the associated activity (You Be the Radiologist! Strain Graphs That Reveal Tumors), students create a graph depicting the location of a tumor amidst fatty tissue, given certain conditions. In the takehome portion of the Go Public phase, students are given three to design a brochure advertising the new form of breast cancer detection to patients and doctors. The brochure should explain how the detection works, its advantages and its disadvantages.
Informative Brochure
Distribute the attached grading rubric to the class. Have each student prepare his/her own brochure and use the grading rubric as a guide in assessing student designs.
Vocabulary/Definitions
cancer: A malignant and invasive growth or tumor tending to recur after removal and to metastasize to other sites.
force: An influence on a body or system, producing a change in movement or in shape or other effects.
spring: An elastic body such as a wire of steel coiled spirally that recovers its shape after being compressed, bent or stretched.
strain: Deformation of a body or structure as a result of an applied force beyond limit.
stress: The physical pressure, pull or other force exerted on a system by another, producing a strain. Measured by the ratio of force to area.
Associated Activities
 You Be the Radiologist! Strain Graphs That Reveal Tumors  Students create a 1D strain plot in Microsoft Excel® depicting the location of a breast tumor amidst healthy tissue. They also create a descriptive brochure. The results of this activity function as proof of the accuracy and reliability of students' breast cancer detection design.
Worksheets and Attachments
Assessment
Embedded Assessment:
Give each student a composite grade based on the graph generated in the associated activity as well as the informative brochure.
