Lesson Plans

Heart Disease: Are You at Risk?:

In this lesson, students will analyze an informational text by the National Institutes of Health that addresses the risk factors for heart disease. The text is broken into three areas: risk factors that can be controlled (like smoking, high blood pressure, and obesity), risk factors that cannot be controlled (like age and family history), and emerging risk factors. This lesson plan is designed to support reading in the content area. The lesson plan includes a note-taking guide, text-dependent questions, a writing prompt, answer keys, and a writing rubric.

Type: Lesson Plan

Heart Rate Activity: Body Positions and Physical Activity:

This is a activity that should be used after a full introduction/lesson for the cardiovascular and circulatory system has been completed. Students should be able to determine how physical body changes affect the heart rate and blood flow.

Type: Lesson Plan

The Dangers of Sticky Blood:

Students will research the dangers of high blood cholesterol levels in humans. The prevention of high cholesterol and lowering of high cholesterol to improve health of individuals will be presented in an informative online newsletter. The newsletters will be utilized to raise community awareness of the issue within the school by printing out the final products and displaying them in the school hallway. The online tool Smore will be used for constructing the newsletter and can be shared on social media to reach those that are not in the school community.

Type: Lesson Plan

HEART HEALTH:

This MEA is designed to educate students about the relationship between fast food choices and heart health. It should give students dietary choices to assist in the prevention of high blood pressure and heart disease.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Type: Lesson Plan

This is not Heart to Learn:

This lesson is about the heart and how it functions. The student will be able to diagram the flow of blood through the heart. The student will also be able to demonstrate how blood pressure is measured and how it can change under various physiological conditions.

Type: Lesson Plan

An Activity on Factors Affecting Blood Flow:

This lesson is designed to explore the relationship between pressure and vessel diameter and to create a model that represents how high blood pressure may affect weakened vessels.
A collaborative work of Melvin Flores, Larie Laudato and Glenn Soltes

Type: Lesson Plan

Blood Flow:

The lesson is design to describe the factors affecting blood flow through the cardiovascular system. The lesson uses the 5E model as an approach for students to become engaged, analytical and inquisitive in learning about the mechanism of blood flow and the importance of this in our body. In addition, the lesson engages the student to test variables that may affect blood flow.

Type: Lesson Plan

Blood Flow Learning Stations:

Students will visit stations that demonstrate each of the factors that affect blood flow through the cardiovascular system.

Type: Lesson Plan

Blood flow: A Student-Centered Inquiry:

This is set of related lessons including direct instruction, games, readings, small group work and an inquiry activity to model factors affecting the human circulatory system.

The Circulatory System and the Heart:

This Khan Academy video explains the major vessels involved in the flow of blood and follows the steps that blood takes as it travels through the heart.

Type: Tutorial

Conducting System of the Heart:

This tutorial will help you to understand how all of the components of the heart are able to work together without direct control from the central nervous system. This video shows that for proper function of the heartbeat, it is necessary that all of the muscle fibers in a region contract in unison.

Type: Tutorial

Baroreceptor Reflex Control of Blood Pressure:

Blood pressure is determined by the force of the blood acting on the walls of the blood vessels. Two factors determine the size of this force. One is the volume of blood being pumped through the vessel. The other is the size of the vessels. Changes in blood pressure can be caused by either a change in the amount of blood being pumped or by a change in the size of the blood vessels. Feedback mechanisms, described in this animation, will alter heart rate and blood vessel dilation to maintain blood pressure at appropriate levels.

Type: Tutorial

Chemoreceptor Reflex Control of Blood Pressure:

This tutorial will help students to understand how concentrations of gases in the blood change during breathing. This animation shows high carbon dioxide concentrations and low oxygen concentrations indicating that gas exchage is occurring at a slower than ideal rate. Because of this, heart rate increases or decreases to compensate the exchange of gas.

Type: Tutorial

How the Heart Actually Pumps Blood:

This TED ED original lesson takes a closer look at how the heart pumps blood. For most of history, scientists weren't quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system.

Zebrafish Heart Regeneration:


This video presentation will help to understand the regeneration process in a zebrafish. When the zebrafish heart is damaged, the wound site is rapidly sealed with a fibrin clot that stems bleeding within seconds. Following clot formation, the tissue that surrounds the heart muscle, the epicardium, gradually covers the fibrin clot via migration and cell division. Over the next few months, new cardiac muscle is produced and replaces the clot.

The Blood Typing Game:

This educational game is about blood types, blood typing, and blood transfusions. Your challenge is to save patients in urgent need of blood transfusions. Your job is to decide what blood type these patients belong to in order to administer safe blood transfusions. At the end you will be evaluated: if you make no mistakes at all you will get all five blood drops.
