Lesson Outline
1. Introduction to Free Diving (5 minutes)
- Begin with a brief explanation of what free diving is.
- Discuss its history and cultural significance, especially in New Zealand.
- Show a short video clip of free divers in action (duration: 2-3 minutes).

2. The Physiology of Free Diving (10 minutes)
- Explain key physiological concepts such as:
- The mammalian dive reflex
- Breath hold techniques
- Oxygen management
- Discuss how the body adapts to pressure changes underwater.
Engagement Activity: Have students do a brief activity where they practice holding their breath safely for a period, discussing their experiences afterward.

3. Safety Practices in Free Diving (5 minutes)
- Outline essential safety measures, including:
- Always dive with a buddy.
- Understanding the risks and having proper training.
- Recognizing the signs of hyperventilation and shallow water blackout.
Discussion Question: Ask students why safety is crucial in free diving and what potential dangers they can think of.
4. Environmental Impact and Conservation (5 minutes)
- Discuss the environmental issues affecting marine ecosystems and how free divers can contribute positively.
- Talk about the importance of responsible diving practices and marine conservation efforts in New Zealand.

5. Wrap-Up and Review (5 minutes)
- Recap key points discussed in the lesson: what free diving is, its physiological effects, safety practices, and its environmental significance.
- Allow time for any questions.
Homework Assignment
-
Research Assignment: Write a short paragraph (100-150 words) on one famous free diver and their contributions to the sport or marine conservation. Include at least one interesting fact.
Correct Answer Example: An example could be Jacques Mayol, who was the first person to break the 100-metre barrier in free diving and advocated for marine conservation through his films.
-
Reflection Question: List at least three safety practices that free divers should follow and explain why each is important.
Correct Answer Example:
- Always dive with a buddy: This ensures that someone is there to help in case of an emergency.
- Know your limits: It prevents accidents caused by trying to dive deeper or hold your breath longer than you are trained for.
- Stay calm: Reduces the risk of hyperventilation and helps in managing breath hold effectively.
Additional Resources
- Link to educational videos on free diving and safety practices.
- Recommended books on marine biology and free diving techniques.
Assessment Criteria
Students will be assessed based on:
- Participation in discussions and activities.
- Completeness and accuracy of the homework assignment.
- Ability to articulate understanding of safety practices during the follow-up discussion.
This lesson plan offers students an engaging way to learn about free diving, while ensuring alignment with New Zealand educational standards and norms.
