Reference Materials
The following resources were used in planning this lesson:
- 9–Years Basic Education Curriculum
- Abuja Educational Resource Centre Scheme of Work
- NAPPS National Unified Scheme of Work
- Online Information from Britannica – Heart | Structure, Function, Diagram, Anatomy, & Facts
- Relevant Textbooks
Instructional Materials
The teacher will teach this lesson with the aid of:
- A labeled model of the human heart
- Charts showing the human circulatory system
- Flashcards with names of heart parts and functions
- Multimedia visuals (if available)
Rationale for the Lesson
Understanding the human heart helps pupils appreciate its role in sustaining life and maintaining good health. This knowledge encourages healthy habits and care for their bodies.
Prerequisite/Previous Knowledge
Pupils have learned about frictional force and its application in the human body, enabling them to relate movement and function to the heart.
Lesson Content
The Human Heart and Its Functions
The human heart is a muscular organ located in the chest, slightly to the left. It is responsible for pumping blood throughout the body via the circulatory system. This ensures that oxygen and nutrients are delivered to every cell while waste products are removed.
Functions of the Heart:
- Pumps oxygenated blood to the body: The heart ensures all body cells receive oxygen.
- Receives deoxygenated blood from the body: It collects used blood for purification in the lungs.
- Maintains blood pressure: The heart helps regulate blood flow and maintain normal pressure levels.
- Distributes nutrients: Blood pumped by the heart carries essential nutrients to cells.
- Supports waste removal: It aids in transporting carbon dioxide and other waste for excretion.
Instructional Procedures
To deliver this lesson, the teacher will adopt the following steps:
| Content Development | Time | Teaching Method | Teaching Strategy | Teacher’s Activity | Pupils’ Activity | Learning Point |
|---|---|---|---|---|---|---|
| Step 1: Introduction | 5 minutes | Set induction | Interactive discussion | Displays the heart model and asks questions about it. | Respond to questions and observe the model. | connect prior knowledge to the topic. |
| Step 2: Explanation | 10 minutes | Expository teaching | Guided explanation | Explains the structure and functions of the heart using the model. | Listen, ask questions, and take notes. | understand heart structure and functions. |
| Step 3: Demonstration | 10 minutes | Demonstration | Visual aids | Points to the parts of the heart model and explains their functions. | Identify and label parts of the heart. | learn to label parts of the heart. |
| Step 4: Group Activity | 7 minutes | Collaborative learning | Group discussion | Divides pupils into groups to discuss the heart’s importance. | Participate in group discussions. | understand the heart’s relevance to life. |
| Step 5: Note-taking | 5 minutes | Expository teaching | Writing activity | Guides pupils to copy key points into their notebooks. | Write down important notes. | summarize the topic in their notes. |
| Step 6: Evaluation | 2 minutes | Questioning | Oral questioning | Asks questions to assess understanding. | Answer questions orally. | comprehension of the topic is evaluated. |
| Step 7: Conclusion | 1 minute | Review | Recap and praise | Summarizes the lesson and encourages healthy habits. | Listen and respond positively. | reflect on key takeaways. |
Lesson Evaluation
To evaluate the learning, the teacher asks pupils to:
- Describe the human heart in simple terms.
- List five functions of the heart.
- Label the parts of a heart diagram.
- Discuss why the heart is important in sustaining life.
Note for Teachers Using This Lesson Plan
Ensure that all pupils actively participate, especially during the group discussion and labeling activity. Use the heart model effectively for clarity. Happy teaching!
