Click on any number to launch the unit of instruction. We suggest that you do "Levels of Organization" first. After that, sequence does not matter.


This "Organ Systems" module has five units of instruction that  focus on the main classes of functions that a body must perform. Rather than just naming organs of the body and what they do, we present a perspective on the body as a coordinated group of systems that must do certain things correctly in order to survive and thrive.

The Module is not intended to replace current curricula, but the units will hopefully provide useful resources and learning activities to complement and enrich current teaching practices. The content is designed for middle-school students, but some of the content may be useful in high school.


Each instructional unit
includes topics on...

• "Why Does It Matter" to explain the significance of the facts and motivate students
"How We Know" to explain how understanding develops
• "What We Know" to summarize main concepts and facts
• "Story Time" a short biographical sketch on famous scientists, emphasizing, where possible, their childhood
• "Activities, Assignments" for application of module content
"Common Hazards" and their effects on organ system functions
•  On-line self-study system, "Get Smart," that operates like "flash cards."
