Exercise Physiology
Explore heart rate, breathing and energy response through a safe, inclusive practical learning sequence designed for Grade 8.
Learning objectives
- Explain key ideas about heart rate, breathing and energy response.
- Plan and perform a safe heart-rate zone investigation.
- Use evidence and feedback to evaluate performance and identify a next step.
MYP PHE + SHAPE America alignment
SHAPE.PE.8.S4
Build and monitor fitness using safe training principles and individual evidence. By Grade 8, students demonstrate increasing independence and complexity.
SHAPE.PE.8.S3
Use knowledge and self-management to sustain regular, health-enhancing physical activity. By Grade 8, students demonstrate increasing independence and complexity.
MYP criteria
- Criterion A — Knowing and understanding
- Criterion D — Reflecting and improving performance
ENGAGE
Prepare and inquire
Begin with a gentle readiness check and identify what you already know about Explore heart rate, breathing and energy response through a safe, inclusive practical learning sequence designed for Grade 8.
Think about it
What would effective, safe and responsible participation look like today?
Hint: Consider technique, communication and evidence.
EXPLAIN
Key knowledge and safety
Effective PHE learning connects accurate knowledge to purposeful action: understand, plan, perform, then use evidence to improve.
Safe and inclusive participation
- Use a gradual warm-up and activity-specific preparation.
- In Qatar’s warmer conditions, use shaded or indoor space where available, pause often and follow school hydration and heat-safety procedures.
- Choose an appropriate intensity and stop for pain, dizziness or unusual discomfort.
- Adapt distance, speed, equipment, role or range of movement so everyone participates meaningfully.
Educational guidance
This lesson supports learning, not medical diagnosis. Follow school procedures and seek a qualified adult or health professional for personal health concerns.
INVESTIGATION
Active learning challenge
Complete the practical challenge described in the objectives. Work for at least half of the session in active practice. Record one observable success, one piece of feedback and one specific adjustment. Finish with a gradual cool-down and reflection.
