No Valve in Vain

Hands-on experience with valves and water flow supports young researchers' understanding of valve operation. Attached resources for learners are text-dense; I'd break up the text into smaller pieces for groups to read and present...

Circulate this news: the heart is a pump containing one-way valves! Following the previous lesson on the external structure of the heart, learners now take a look at the inside. They use a three-color diagram to label a black-and-white...

Put your heart into it. Scholars design and build replacements for mitral heart valves. Obviously, they can't test their creations on a real heart, so a box with marbles (to represent blood cells) will suffice.

Students design a pumping device that will effectively pump fluid through a model "cardiovascular system." They explore the effects of too much and too little pressure on a circulatory system.

Students learn how healthy human heart valves function and the different diseases that can affect heart valves. They also learn about devices and procedures that biomedical engineers have designed to help people with damaged or diseased...

Understand how the human heart pumps and controls the blood flow in the body.

In this effective site, students will name the parts of the heart and trace the flow of blood through the body. Contains related links.

In this activity, students will design and create their own heart valves out of a variety of materials given to them, including: waterproof tape, plastic tubing, flexible plastic sheets, foam sheets, scissors, clay, etc. This activity...

This lesson contains background about the blood vascular system and the heart. Also, the different sizes of capillaries, veins, and arteries, and how they affect blood flow through the system. We will then proceed to talk about the...

Students use their knowledge about how healthy heart valves function to design, construct and implant prototype replacement mitral valves for hypothetical patients' hearts. Building on what they learned in the associated lesson about...
