Edheads Lesson: No Valve in Vain Posted on February 8th, 2013 by Mary Lord Lesson from Contributed by the Techtronics Program, Pratt School of Engineering, Duke University. Note: This activity, part of a teachengineering curricular unit on Engineering and the Human Body that includes a lesson on the heart, could be enhanced with two preliminary heart-valve activities – Engineering the Heart and Saving a Life: Valve replacement Grade level: 6 – 8Time: 90 minutes Summary In this activity, teams of middle school “biomedical engineers” will learn about the engineering design process and how a one-way valve works by creating heart valves from tape, plastic tubing and a variety of other materials. Learning Objectives After doing this activity, students should be able to: Standards International Technology and Engineering Educators Association E. National Science Education Standards Form and function are complementary aspects of objects, organisms, and systems in the natural and designed world. Materials Procedure

Straw Bridges - Activity - Summary Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design, while meeting the design criteria and constraints. They experiment with different geometric shapes and determine how shapes affect the strength of materials. Let the competition begin! Engineering Connection Beam bridges are the most common type of bridge designed by engineers and relatively easy to imagine and build. Educational Standards Each TeachEngineering lesson or activity is correlated to one or more K-12 science, technology, engineering or math (STEM) educational standards. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standard Network (ASN), a project of JES & Co.
