Lesson Duration: 45 minutes
Week & Period: Week 33, Period 6
Topic: Exercises for Heart Health
Sub-topic: Aerobic, Flexibility, and Heart Rate Screening
Learning Objectives
By the end of the lesson, students should be able to:
Demonstrate aerobic exercises such as jogging, skipping, and jumping jacks. Perform flexibility and stretching routines. Observe and record heart rate before and after exercises to understand how physical activity affects the heart.
Previous Knowledge
Students already know basic movements and have observed their heartbeat in previous lessons.
Instructional Materials
Mats, cones, stopwatch, charts of exercises, open space for aerobics, stethoscopes.
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher leads learners in light jogging and dynamic stretches. Learners are asked: “How does your heart feel when you move quickly?” This introduces aerobic exercise and its impact on heart health.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Definition and Explanation:
- Aerobic exercises are activities that make the heart beat faster and the body breathe more to supply oxygen to muscles. Examples include jogging, skipping, and jumping jacks.
- Flexibility exercises involve stretching muscles and joints to improve movement and prevent injuries. Examples include arm stretches, leg stretches, and torso bends.
- Explain in simple terms: “Aerobic exercises make your heart strong, and flexibility exercises keep your body loose so you can move easily.”
Demonstrations and Examples:
- Teacher demonstrates jogging on the spot, emphasizing proper arm movement, foot placement, and steady breathing.
- Skipping rope is demonstrated slowly, highlighting rhythm and coordination.
- Jumping jacks are performed step by step, counting repetitions aloud.
- Flexibility exercises are shown gradually, e.g., reaching arms overhead, touching toes, side bends, and gentle torso twists.
- Teacher measures own pulse before and after exercises to show the change.
Practical Activities:
- Learners perform 3–5 minutes of aerobic exercises, rotating through jogging, skipping, and jumping jacks.
- Learners perform flexibility exercises, holding each stretch for 10–15 seconds, ensuring correct posture.
- Learners measure heart rate before and after exercise using pulse points or stethoscopes.
- Learners record their heart rates in a chart and discuss how exercise changed their heartbeat.
- Emphasis on breathing properly, moving safely, and avoiding overexertion.
Learners’ Activities (Expanded):
- Learners perform exercises in small groups or pairs, observing each other for correct form.
- Learners rotate through stations: one for jogging, one for skipping, one for jumping jacks, one for stretches.
- Learners count heartbeats in 15 or 30 seconds and calculate beats per minute.
- Learners discuss in pairs or groups: “Which exercise made your heart beat fastest?” and “Which stretch felt best for your body?”
- Reflection: Learners write or draw how their body feels before and after exercise.
Assessment Checks:
- Teacher observes learners performing exercises correctly and safely.
- Oral questions:
- “Which exercise made your heart beat faster?”
- “Why is stretching important before and after exercise?”
- “How does exercise help your heart stay healthy?”
- Teacher checks recorded heart rate charts for accuracy.
Notes (Expanded & Detailed):
- Aerobic exercises strengthen the heart, improve lung capacity, and increase overall endurance.
- Flexibility exercises enhance posture, reduce muscle stiffness, and prevent injuries.
- Monitoring heart rate before and after exercise teaches learners the connection between activity and cardiovascular health.
- Practicing in groups builds teamwork and encourages correct technique.
- Safety, proper breathing, and gradual progression are essential to avoid fatigue or injury.
- Reflection and discussion reinforce understanding of exercise benefits and how it supports physical fitness and heart health.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Learners demonstrate one aerobic and one flexibility exercise and explain how it affects the heart. Teacher reinforces safe exercise practices and cardiovascular benefits.
Evaluation Method (Expanded)
Exit slip/quiz: Learners answer: 1. Name one aerobic exercise. 2. Why do we stretch before and after exercise? 3. How does exercise affect your heart rate? Teacher collects slips and provides oral feedback.
Assignment (Expanded)
Learners practice one aerobic and one flexibility exercise at home and observe changes in heart rate.
Follow-up Activity
Next lesson will focus on games that promote heart fitness, including classroom, locomotor, and manipulative games.
Differentiation / Inclusive Strategies
Learners who struggle with high-intensity exercises can perform modified movements or slower-paced versions. Peer assistance ensures inclusivity.
