SummaryIn this unit, students learn about the form and function of the human heart through lecture, research and dissection. Following the steps of the Legacy Cycle, students brainstorm, research, design and present viable solutions to various heart conditions as presented through a unit challenge. Additionally, students study how heart valves work and investigate how faulty valves can be replaced with new ones through advancements in engineering and technology. This unit demonstrates to students how and why the heart is such a powerful organ in our bodies.
When engineers design solutions to problems, they first gather information—background information about the system they are working with, testing and analysis data that they collect from various materials, and information from experts more familiar with the subject. To design medical devices, technologies and procedures, biomedical engineers must understand how the human body functions, as well as how disease and disorders affect the body. In addition to knowledge gained through education and experience, engineers use problem-solving skills every step of the way in designing devices, tools, products, structures and processes that improve our society.
Your grandmother, who has been a non-smoker and relatively healthy throughout her life, has recently noticed that she is becoming increasingly short of breath as she does simple things, such as climbing the steps in her house. She has also noticed that her heart rate increases when she does mild exercise, such as walking to the mailbox or going upstairs. What could be causing this? Is it just due to her getting older? Is there reason to be concerned? What can be done to help her?
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 Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.
