Students learn about the heart and its role at the center of the human cardiovascular system. In the associated activity, students play out a scenario in which they are biomedical engineers asked to design artificial hearts. They learn about the path of blood flow through the heart and use that knowledge to evaluate designs of artificial hearts on the market.

This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).

Students learn about the form and function of the human heart through lecture, research and dissection. They brainstorm ideas that pertain to various heart conditions and organize these ideas into categories that help them research possible solutions. An expert in the field of cardiac valve research was interviewed for this lesson and shares his ideas with the class. Students conclude by researching various possible heart defects.

The Circulation Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.

The Med Help Support Communities provides questions and answers about most medical conditions as well as allowing you to type in a question and get a reply from a doctor.

The Merck Manual describes the human heart and shows how the heart pumps blood. Includes interactive 3D models.

Students learn about the form and function of the human heart through the dissection of sheep hearts. They learn about the different parts of the heart and are able to identify the anatomical structures and compare them to the all of the structural components of the human heart they learned about in the associated lesson, Heart to Heart.

Students use provided materials to design and build prototype artificial heart valves. Their functioning is demonstrated using water to simulate the flow of blood through the heart. Upon completion, teams demonstrate their fully functional prototypes to the rest of the class, along with a pamphlet that describes the device and how it works.

Grover is using a stethoscope to listen to his heartbeat. His heart is beating slowly because Grover is calm. When he listens to a chicken's heartbeat after she's been running, he hears it beating very quickly. Moving around, or exercising, causes the heart to beat faster and makes the heart stronger. This resource focuses on physical health. [2:30]

Acting as biomedical engineers, students design, build, test and redesign prototype heart valves using materials such as waterproof tape, plastic tubing, flexible plastic and foam sheets, clay, wire and pipe cleaners. They test them with flowing water, representing blood moving through the heart. As students creatively practice engineering problem solving, they demonstrate their understanding of how one-way heart valves work.

Shows activities children do that keep their hearts healthy. Includes audio narration in 13 additional languages with text in English.

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 heart's function in the blood vascular system. This will lead into a discussion of heart valves, how they work and what might cause them to fail. Then we will discuss prosthetic heart valves.

Do you know how to get to Sesame Street? This collection is designed to engage preschoolers in everyday learning by teaching core skills in Math, Literacy, STEM, and Social and Emotional Development. Here you'll find hundreds of videos, games, and printable materials to help you to excite even the youngest learners.

In this lesson the students will learn how the heart functions. Students will be introduced to the concept of action potential generation. The lesson will explain how action potential generation causes the electrical current that causes muscle contraction in the heart. Students will be introduced to the basic electrical signal generated by the heart; P, QRS, and T waves. The lesson will approach the heart from an engineering standpoint and encourage students to design ways to improve heart function. Students will also learn the basic steps of the engineering design process.

Explore Edgar Allan Poe's famous short story, "The Tell-Tale Heart," in this video [3:05] from the American Masters film Edgar Allan Poe: Buried Alive. Discussion questions, teaching tips, and a student handout ask students to analyze the work while also learning more about the art of writing a short story. Students are asked to consider why the story remains popular today, connections to music, and how Poe hooks readers from the very first sentence.

AmericanPresident offers a comprehensive overview of the 1964 campaign and election of Lyndon Baines Johnson. Content includes a focus on the separate campaigns waged by Johnson and his challenger, Barry Goldwater.

Read and watch how the blood, the heart, and the blood vessels keep the blood flowing through our bodies. [6:00]

Students are presented with the unit's grand challenge problem: You are the lead engineer for a biomaterials company that has a cardiovascular systems client who wants you to develop a model that can be used to test the properties of heart valves without using real specimens. How might you go about accomplishing this task? What information do you need to create an accurate model? How could your materials be tested? Students brainstorm as a class, then learn some basic information relevant to the problem (by reading the transcript of an interview with a biomedical engineer), and then learn more specific information on how heart tissues work their structure and composition (lecture information presented by the teacher). This prepares them for the associated activity, during which students cement their understanding of the heart and its function by dissecting sheep hearts to explore heart anatomy.

Students learn how to take blood pressure by observing a teacher demonstration and then practicing on fellow classmates in small groups. Once the hands-on component of this activity is completed, the class brainstorms and discusses how blood pressure might affect a person's health. This activity acts as hook for the second lesson in this unit, in which blood pressure is presented in detail, as well as how variances in blood pressure can affect a person's cardiovascular system.
