In 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

Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers help us stay healthy by designing machines and medicines that support respiratory health and function.

Students learn about the form and function of the human heart through lecture, research and dissection. They brainstorm ideas that pertain to various heart conditions and organize these ideas into categories that help them research possible solutions. An expert in the field of cardiac valve research was interviewed for this lesson and shares his ideas with the class. Students conclude by researching various possible heart defects.
