Sounds of the Heart

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...

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...

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.

Make music. Class members construct a simple record player using a paper cone and a pin. The resource provides a description of what is happening and why listeners can hear the sounds through the cone. 

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...

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...

Learners name the main parts of the heart and what events occur there. They write a reaction that contains complete sentences, and uses proper spelling and grammar, after viewing a video. Students define the following terms: contraction,...

Students explore the heart and its functions. In this lesson plan about the heart, students use observation to understand the heart. Students construct a heart model, watch the vibration of their pulse, and listen to a heartbeat with a...

Middle schoolers design and create their own heart valves out of a variety of materials. Their heart valves are one way valves designed for water flowing through a tube representing blood moving through the heart.

If you've ever wondered how your heart works, this movie and activity guide has the answer. [6:15]
