Week & Period: Week 32, Period 6
Topic: Function of the Heart Muscle
Sub-topic: Location and Functions of the Heart
Learning Objectives
By the end of the lesson, students should be able to:
Locate the heart in the human body. Identify three main functions of the heart: pumping blood, delivering oxygen and nutrients, and removing waste. Demonstrate heartbeat using pulse or a stethoscope.
Previous Knowledge
Students already know that the heart is a vital organ and have some experience observing their own heartbeat during physical activity.
Instructional Materials
Stethoscopes, charts of the human body, diagrams of the heart, stopwatch, open space for practical demonstrations.
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
The teacher asks learners: “What organ in your body helps you stay alive and active?” Learners respond, leading to a discussion about the heart. Light jogging and arm stretches are performed to prepare learners for observing their own heartbeat.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Definition and Explanation:
- The heart is a strong, muscular organ located in the chest slightly to the left.
- It is essential for circulating blood throughout the body.
- The three main functions of the heart are:
- Pumping blood to all parts of the body.
- Delivering oxygen and nutrients to organs, muscles, and tissues.
- Removing waste products such as carbon dioxide from the body.
- Explain in child-friendly terms: “The heart is like a pump that keeps your body alive, helps you run, play, and grow.”
- Discuss why a healthy heart is important for physical fitness and overall well-being.
Demonstrations and Examples:
- Teacher shows a diagram or model of the heart and points to major parts.
- Teacher demonstrates pulse measurement at the wrist and neck.
- Learners are shown how to listen to their heartbeat using a stethoscope if available.
- Teacher performs a mini-exercise (marching in place or light jogging) to demonstrate increase in heart rate.
Practical Activities:
- Learners locate their pulse points (wrist or neck) and count their heartbeat at rest for 15–30 seconds, then calculate beats per minute.
- Learners perform light exercises (walking, jogging, or jumping in place) for 1–2 minutes.
- Learners measure heartbeat again to observe the change.
- Learners compare resting and active heart rates and discuss why the heart beats faster during exercise.
- Learners reflect on how the heart helps them play, study, and stay healthy.
Learners’ Activities (Expanded):
- Practice finding pulse in pairs, helping each other count correctly.
- Perform light exercises safely under teacher supervision.
- Record heartbeat before and after exercise in notebooks or charts.
- Discuss in small groups: “What does your heart do?” and “Why does it beat faster when you run?”
- Share observations about heart rate differences between boys and girls, or between learners who exercised more vigorously.
Assessment Checks:
- Teacher observes correct pulse measurement and safe participation in exercises.
- Oral questions:
- “Where is your heart located?”
- “Name one function of the heart.”
- “How does exercise affect your heartbeat?”
- Learners demonstrate finding their pulse and explain what happens when the heart beats faster.
Notes (Expanded & Detailed):
- The heart is a muscular organ that pumps blood to supply oxygen and nutrients and remove waste.
- Understanding the heart’s function helps learners connect exercise with health.
- Measuring pulse before and after activity shows how exercise affects cardiovascular function.
- Proper technique, safety, and observation are essential to prevent injury or mismeasurement.
- Activities develop awareness of body function, responsibility for health, and understanding of physical fitness.
- Encouraging reflection and discussion builds comprehension and critical thinking about the heart’s role in daily life and exercise.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Learners demonstrate how to measure pulse and explain one function of the heart. Teacher reinforces the importance of heart health in daily activities and physical fitness.
Evaluation Method (Expanded)
Exit slip/quiz: Learners answer: 1. Where is the heart located? 2. Name one function of the heart. 3. How does exercise affect your heartbeat? Teacher collects slips and provides oral feedback.
Assignment (Expanded)
Learners observe their pulse before and after walking or running at home and note any changes.
Follow-up Activity
Next lesson will cover exercises for heart health, including aerobic and flexibility routines, and mini fitness screening for heart rate.
Differentiation / Inclusive Strategies
Learners who find pulse measurement difficult can work in pairs or focus on listening to the heartbeat using a stethoscope. Demonstrations are repeated for clarity.
