In this lesson plan site, the students will learn about the circulatory system and perform an experiment where they take their pulse after various activities.

Investigate the evolution of the heart and circulatory system in mammals by studying the anatomy of hearts in other animals. Create models of the hearts of fish, amphibians and mammals.

A digital diagram from Digital Frog of the circulatory system of a frog. Very nice, and very fake since it is not a real frog.

This feature from the NOVA: "Cut to the Heart" highlights facts about the heart, including its size and placement, and will help you to understand the importance of this wondrous organ in our bodies.

A very good site about the circulatory system of a bird. It is reader friendly, and includes a fair amount of information. Good diagram of the circulatory system.

Understand the basic characteristics of circulation in the Chesapeake Bay, by allowing learners to change the wind speed and velocity, and the freshwater forcing through a number of subestuaries, and observe the resulting surface height,...

The circulatory system transports substances between the exchange surface and cells. It delivers oxygen and glucose to the tissues for respiration, which is the release of energy to cells.

This unit invites students to learn about the history of slavery at select schools in the United States and how these schools taught the "science" of racial inferiority. The goal is for students to work in collaborative groups to produce...

A model organizes what we think we know about something in order to predict how it might behave in the present, future, or past as well as how it might respond to external influence. Models are especially useful when direct, controlled...

In this lesson students will use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the body.
