Lesson 3 : Engineer

Time Required: 200 minutes
In The Engineer, students will:

Design a solution that addresses one of the following problems in a working body system; a blood vessel blocked by plaque, airways obstructed due to asthma, a stroke that kills nerve cells in the brain due to lack of oxygen, or weakened muscles from muscular dystrophy. They will then communicate understanding that a malfunction in one body system affects the function of the body as a whole.

Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. [Clarification Statement: Emphasis is on the conceptual understanding that cells form tissues and tissues form organs specialized for particular body functions. Examples could include the interaction of subsystems within a system and the normal functioning of those systems.] [Assessment Boundary: Assessment does not include the mechanism of one body system independent of others. Assessment is limited to the circulatory, excretory, digestive, respiratory, muscular, and nervous systems.]
