Lesson plan
Choose activities from the following suggestions to customize your lesson to the needs of your class.
Heart Facts
What do you know?
Write out the key words on a piece of chart paper or a white board with the word “heart” in the centre. Review the
new vocabulary and have students who know the words help explain them to others. Use simple word games such as
identifying, sounding out, underlining for unfamiliar words.
Use leading questions such as those below to ask what students know about the heart and health. Record what they
say on a chart using words and simple drawings such as drawing a stick figure with the heart in the centre, or simply
writing the word “centre”.
•Where is the heart located? In the middle of the chest.
•How big is the heart? About the size of a fist.
•What does the heart do in the body?
It pumps blood to the different parts of the body.
•What sounds does the heart make?
It makes a thumping noise in the chest.
•What does the heart look like?
It’s a bit like a fat, rounded valentine shape with veins and arteries attached.
Explain that people can feel their heart beat at pulse points. Have students
find their wrist pulse point on the thumb-side of the inner wrist, just up from
the joint and count their own pulse. Option: Have students squeeze a soft
ball in time to a heart rhythm and discuss how much energy it takes.

The Powerful Heart – The Heart and The Circulatory System
Write the words “I want to know” on a large piece of chart paper.
•Ask students to discuss in groups how they would complete the sentence, “What I want to know about my heart is”
and have them write their ideas on a sheet of paper.
•Ask each group what their group wants to know and have them write their ideas on the chart.
•Have students review the ideas on the chart. Explain that the class will learn about the heart and students can find
the answers to their questions. If they have more questions, they will be added to the chart.
Refer to the chart through subsequent activities to answer questions. Record what students have learned or to add
more questions that students raise.
The Circulatory System
Distribute the activity sheet “The Circulatory System.”
Ask students to explain what the heart and lungs do. Explain that:
• The heart pushes blood through arteries to all parts of the body. Blood returns to the heart through the veins.
• The lungs infuse the blood with oxygen from the air and get rid of waste.
• The blood carries oxygen and food through the arteries to keep the body healthy and strong.
• The blood also carries waste away from the body.
• All the parts – the heart, lungs, blood, arteries and veins – work together as part of the circulatory system.
THREE KEYS TO HEART HEALTH
•Write the word “healthy” on the board and ask students for ideas about
what it means. Write their responses in a web on the board. Probe for a
variety of responses such as feeling good, the ability to play and have fun
and not being sick in bed.
•Explain that being healthy means feeling good about what you are able to do. This means feeling good in your body,
feeling happy, feeling good about your family and friends. These are different ways of being healthy.
Point out that people with disabilities can still have good health, although they might be unable to do certain things.
Ask students what they do to stay healthy. Write their responses in a web on the board. Prompt students with the
following questions:
•Does playing active games make you feel healthy?
•Does eating good food make you feel healthy?
•Does it feel healthy when you stay away from tobacco smoke?
•How can you keep your heart healthy?
Point out the three keys to good health: Eat good food, get active play, live smoke-free.

The Powerful Heart – The Heart and The Circulatory System
Review and summary
Review the key messages of the lesson:
•The heart beats in the chest to keep the body healthy.
•The heart pumps blood through the body providing fresh oxygen and nutrients.
•Blood is pumped from the heart through arteries to the lungs and back through veins to the heart.
•The three keys to a healthy heart are to eat good food, get active play and live smoke-free.
Home connections
• Invite students to take home “The Circulatory System” activity to show their parents or guardians and explain what
they learned about the heart.
• Have students and families use the internet to find animations of the heart and circulatory system.
Extension and integration
•Have students mimic the sound of the heart, and chant, clap, stamp or use musical instruments to beat the rhythm.
•Invite the school nurse to visit the class. Have students listen to their own hearts using a stethoscope. If available,
use a microphone and portable stereo to amplify sounds from the stethoscope so that the whole class can hear.
•Show a video animation of how the heart and circulation system work. Have the class brainstorm all the facts
about the heart that they did not know before.
•Have students pump water from a squeeze bottle through rubber tubing to see how pressure forces liquid to move.
Have students feel the tubing to feel the water pulse through it when the bottle is pumped. Explain that this is
similar to blood being pumped through the arteries.
Assessment
•Review students’ drawings to ensure they can identify and
correctly draw and label the circulatory system on an
outline of a body.
•Monitor students’ responses to the health discussion to ensure
they can describe practices that contribute to good health including
healthy eating, physical activity and living smoke-free. Have them restate
the three keys to heart health.

the circulatory system
The circulatory system is very complex. The heart pushes blood through the arteries to
all parts of the body and it returns to the heart through the veins. The lungs let the blood
get oxygen from the air and remove waste. The blood carries oxygen and food through
the arteries to keep the parts of the body healthy and strong. The blood also carries
waste away from the parts of the body. All the parts - the heart, lungs, blood,
arteries, and veins - work together as part of the circulatory system.
Count slowly from 1 to 26. That’s how long it takes your blood to make one entire trip!
