Students are introduced to the concept and steps of the engineering design process and taught how to apply it. Students first receive some background information about biomedical engineering (aka bioengineering). Then they learn about material selection and material properties by using a provided guide. In small groups, students learn of their design challenge (improve a cast for a broken arm), brainstorm solutions, are given materials and create prototypes. To finish, teams communicate their design solutions through class poster presentations.

Biomedical engineers who specialize in biomaterials, test and develop new materials that can be safely implanted in the body. Engineers who work in biomechanics apply principles from physics to biological systems. They develop artificial organs, such as the artificial heart. A strong background in material science is required to be able to design these these implants. Learn about different engineering disciplines.Use the engineering design process to solve a specific design task.Learn how to evaluate and choose materials based on material properties.Explore the concept of a prototype.Sketch and build a prototype of their design including a cross-section.Explore the field of biomedical engineering.Develop methods for communicating their design solutions to a larger group.343TeachEngineering.orgConnie Boyd, Terri Camesano, Emine Cagine, Angela Lamoureux, Hilary McCarthy, Robin Scarrell, Suzanne Sontgerath, Katherine Youmans, Tufts Universityhttp://www.teachengineering.org/collection/wpi_/activities/wpi_broken_bones/introduction.dochttp://www.teachengineering.org/collection/wpi_/activities/wpi_broken_bones/introduction.pdfhttp://www.teachengineering.org/collection/wpi_/activities/wpi_broken_bones/worksheet.dochttp://www.teachengineering.org/collection/wpi_/activities/wpi_broken_bones/worksheet.pdfhttp://www.lbl.gov/MicroWorlds/module_index.htmlhttp://www.mse.vt.edu/academics/news/MW_v1n1.pdfhttp://www.mse.cornell.edu/research/bioinspired_materials.cfmhttp://www.teachengineering.org/engrdesignprocess.phpS1012153MassachusettsScience2.1 Identify and explain the steps of the engineering design process, i.e., identify the need or problem, research the problem, develop possible solutions, select the best possible solution(s), construct a prototype, test and evaluate, communicate the solution(s), and redesign.68S1009558MassachusettsScience2.2 Demonstrate methods of representing solutions to a design problem, e.g., sketches, orthographic projections, multiview drawings.68S1011180MassachusettsScience2.3 Describe and explain the purpose of a given prototype.68S1010C69MassachusettsScience2.4 Identify appropriate materials, tools, and machines needed to construct a prototype of a given engineering design.68S1004F28MassachusettsScience2.5 Explain how such design features as size, shape, weight, function, and cost limitations would affect the construction of a given prototype.68United StatesCopyright 2012 - Center for Engineering Educational Outreach, Tufts Universityhttp://www.teachengineering.org/policy_ipp.phphttp://www.teachengineering.org/2012-03-188Teacher
