Ever wonder what the villi in the small intestine do? I bet your class would love to find out. Mesh netting is used to represent small blood vessels on the outside of the intestine, and a chenille bath mat is used to represent the villi...

Middle schoolers demonstrate what they know about the structure and function of the heart and blood vessels. A set of 15 multiple-choice questions also addresses how the heart handles microgravity and how animals without...

Students design a proportional model of blood out of red gelatin, a plastic bag, and rice. They study the components that make up blood and investigate what happens when the arteries in different scenerios. They work in pairs in order to...

How can the circulatory system compare to a city map? Pupils distinguish the "roadways" and "vehicles" of the cardiovascular system, compare the anatomy and function of veins and arteries, and review different types of blood cells with...

High schoolers are able to identify the components of the cardio-vascular system. They are able to describe the way the heart works to pump the blood. Students are able to explain the function of the cardio-vascular system. They are...

Use the pump from a spray bottle to drive a model of the heart in action! In addition to modeling the function of the heart and blood vessels, aspiring anatomists also simulate arterial blockage. They compare the effects of increased...

Students study the heart and the circulatory system. They practice taking their pulse. They create a model of blood cells and squeeze tennis balls to demonstrate just how hard the heart muscle works.

A lab in which high schoolers examine the difference between arteries and veins. Budding biologists will find out which blood vessel can stretch furthest, recording their data in a table then answering several questions evaluating their...

Students explore the circulatory system of animals. Using the Internet, students research animals without circulatory systems. They identify the three types of blood vessels and describe the flow of blood through the heart. Finally,...

Explore the circulatory system with a cardiovascular pump activity that promotes discovery and discussion as class members create a functioning model of the heart. Continue the learning process through a web quest showcasing the...

Students investigate blood moving in the fin of a fish. In this blood circulation lesson, students use a goldfish wrapped in water soaked absorbent cotton, placed in a large petri dish, then placed until a lighted microscope in order to...

What do a dead fish, conservation, and paint have in common? The answer is a great lesson about fish anatomy, fun print making techniques, and unsustainable fishing practices. The class will start by making fish prints with a...

Fourth graders explore the basic function of the heart, identify blood vessels and coronary arteries. They identify good and bad health behaviors and discuss how these behaviors affect the heart. Students explore how the coronary...

Students discuss the importance of the circulatory system and how drugs and alcohol can affect our bodies. They interact with a CD ROM and then outline their bodies and label the parts of their heart and the blood vessels throughout the...

Students investigate the human eye. In this biology lesson, students read the book Look At Your Eyes and locate the various parts of their eye. Students play the game "I Spy."

Fifth graders investigate the path of their blood through their heart and body.  In this heart lesson, 5th graders recognize that blood travels in one direction through arteries and one through veins. Students complete worksheet...

Third graders explore the human heart and the circulatory system. They observe how exercise affects the heart rate and how blood vessels carry blood through the heart and body. Students observe how the blood is carried to and from the...

Students list and describe the purpose/function of blood vessels (arteries, veins and capillaries). They explain how blood flows through the body, and the role of physical activity and how it strengthens the heart.

Learners explore various parts of the heart and blood vessels . They begin with an overview of the components of the cardiovascular system. They see a cross section of an artery and watch how a blood clot develops.

If you're looking for copious background information to support study of the human heart, here it is! You can find photos of hearts, and text about the development, structure, systems, and monitoring that support heart function. Also...

Students name the vessels and parts of the heart. They trace the path of blood through the heart. Students examine the function of the circulatory system. They recognize the differences between a hear when the body is at rest opposed to...

Students study the different facets of the Human immune system, including the functions of all the different organs in the immune system.

First graders explore the circulatory system and its functions. They draw and label the parts of the circulatory system on traced body paper cutouts, and walk on a large chalk outline of a body, following the path of the circulatory system.

Students identify the 4-chambers and major blood vessels of the heart and construct a model of a 4-chamber heart. They sketch their model, identify the chambers/vessels, state the condition of the blood in each chamber/vessel, and...
