4th Grade Blood Circulation Lesson Plan Example

Topic:Blood Circulation

Objectives & Outcomes

• Students will understand the structure and function of the heart and how it maintains blood circulation throughout the body.

Materials

• Whiteboard and markers
• Images of the heart and blood vessels
• Popsicle sticks or tongue depressors (optional)

Warm-up

• Have students stretch their arms overhead and raise their hands if they can name one part of the body where blood comes from and where it goes.
• Write their answers on the board: "blood comes from the heart and goes to the rest of the body."
• Ask what they know about the heart and how it keeps blood flowing to the body.

Direct Instruction

• Show the model of the heart to the students and explain that this model shows the chambers and valves of the heart.
• Explain that blood enters the heart through the superior vena cava and inferior vena cava, which are large veins that carry blood back to the heart.
• As you explain, point to the model of the heart and show the students where the superior vena cava and inferior vena cava enter the heart.
• Show the students the model of the heart with the ventricles and atria removed to show the chambers and valves.
• Explain that blood enters the heart through the superior vena cava and inferior vena cava, and then it is pumped out of the heart through the aorta, the largest artery in the body.
• Explain that the blood is pumped out of the heart through the aorta by the beating heart's ventricles, which are the lower two chambers of the heart.
• Show the students the model of the heart with the ventricles removed to show the chambers and their valves.
• Point to each chamber and its valve, and explain their functions:
• The right ventricle pumps blood to the lungs through the pulmonary artery, where it receives oxygen.
• The left ventricle pumps blood to the rest of the body through the aorta.
• Show the students pictures of the heart and its chambers, valves, and arteries.
• Have the students label the pictures and identify the chambers, valves, and arteries.

Guided Practice: Blood Circulation

• Have the students work in pairs to complete a worksheet on the blood circulation system.
• The worksheet should include:
• A diagram of the heart showing the chambers and their functions
• A diagram of the blood circulation system showing the arteries and their functions
• A labeled diagram of the heart and blood circulation system
• Have the students work in pairs to complete the matching activity, matching the blood vessels to their functions.
• Have the students work in pairs to complete the connect the arteries puzzle, matching the arteries to their functions.
• Have the students work in pairs to complete the cut and paste activity, cutting out the labeled diagrams of the heart and blood circulation system and pasting them into the correct order.
• Have the students work in pairs to complete the quiz on the blood circulation system.
• The quiz should include multiple choice and short answer questions on the following topics:
• The structure and function of the heart
• The structure and function of the blood vessels
• The function of the heart's ventricles
• The function of the aorta
• Have the students complete the post-test on the blood circulation system.
• The post-test should include multiple choice and short answer questions on the following topics:
• The structure and function of the heart
• The structure and function of the blood vessels
• The function of the heart's ventricles
• The function of the aorta

Independent Practice: Blood Clotting

• Have the students work in pairs to complete a worksheet on blood clotting.
• The worksheet should include:
• A labeled diagram of the blood clotting process
• Multiple choice questions on the blood clotting process
• Have the students work in pairs to complete the matching activity, matching the stages of blood clotting to their descriptions.
• Have the students work in pairs to complete the connect the stages of blood clotting puzzle, matching the stages of blood clotting to their descriptions.
• Have the students work in pairs to complete the cut and paste activity, cutting out the labeled diagram of the blood clotting process and pasting it into the correct order.
• Have the students work in pairs to complete the quiz on the blood clotting process.
• The quiz should include multiple choice and short answer questions on the following topics:
• The structure and function of the blood clotting process
• The stages of blood clotting
• Have the students complete the post-test on the blood clotting process.
• The post-test should include multiple choice and short answer questions on the following topics:
• The structure and function of the blood clotting process
• The stages of blood clottingIndependent Practice: Blood Types
• Have the students work in pairs to complete a worksheet on blood types.
• The worksheet should include:
• Multiple choice questions on the different blood types
• Have the students work in pairs to complete the matching activity, matching the blood types to their descriptions.
• Have the students work in pairs to complete the connect the blood types puzzle, matching the blood types to their descriptions.
• Have the students work in pairs to complete the cut and paste activity, cutting out the labeled diagrams of the different blood types and pasting them into the correct order.
• Have the students work in pairs to complete the quiz on the blood types.
• The quiz should include multiple choice and short answer questions on the following topics:
• The different blood types
• Have the students complete the post-test on the blood types.
• The post-test should include multiple choice and short answer questions on the following topics:
• The different blood typesIndependent Practice: Blood Donation
• Have the students work in pairs to complete a worksheet on blood donation.
• The worksheet should include:
• Multiple choice questions on blood donation
• Have the students work in pairs to complete the connect the stages of blood donation puzzle, matching the stages of blood donation to their descriptions.
• Have the students work in pairs to complete the cut and paste activity, cutting out the labeled diagrams of the stages of blood donation and pasting them into the correct order.
• Have the students work in pairs to complete the quiz on blood donation.
• The quiz should include multiple choice and short answer questions on

the following topics:

• The process of blood donation
• The stages of blood donation
• The benefits of blood donation
• The risks of blood donation
• Have the students complete the post-test on blood donation.
• The post-test should include multiple choice and short answer questions on the following topics:
• The process of blood donation
• The stages of blood donation
• The benefits of blood donation
• The risks of blood donationClosure
• Review the main points of the lesson:
• Blood circulation, the structure and function of blood vessels, the flow of blood through the vessels, the different stages of blood clotting, and blood types.
• Discuss the importance of blood in our bodies and the risks and benefits of blood donation.
