📋 Lesson Activities
Activity 1: Body Systems Carousel (10 minutes)
⏱️ 0-10 min🎯 Purpose:
Activate knowledge about body systems and appreciate the complexity of taha tinana
👩🏫 Teacher Instructions:
- Set Up Stations (before class): Create 5 stations around the room with chart paper labelled:
- Station 1: Circulatory System (Heart & Blood)
- Station 2: Respiratory System (Lungs & Breathing)
- Station 3: Digestive System (Food & Nutrients)
- Station 4: Muscular/Skeletal System (Movement & Support)
- Station 5: Nervous System (Brain & Signals)
- Form Groups (1 min): Divide class into 5 groups, one per station
- Station Rotations (7 min): Groups spend ~1.5 minutes at each station, writing:
- What this system does
- Why it matters for health
- One way to keep it healthy
- Quick Gallery Walk (2 min): Students do a fast walk to see all responses
👥 Student Actions:
- Work collaboratively in groups
- Recall prior science knowledge about body systems
- Add new ideas to each chart paper
- Move quickly between stations
🎨 Differentiation:
Support: Provide picture cards of each body system for visual reference. Allow students to draw instead of write.
Extension: Ask groups to identify connections between systems (e.g., circulatory brings oxygen from respiratory to muscles)
Activity 2: The Big 3 - Nutrition, Exercise, Sleep (15 minutes)
⏱️ 10-25 min🎯 Purpose:
Teach the three essential pillars of physical wellbeing with specific teenage needs
👩🏫 Teacher Instructions:
- Introduce The Big 3 (2 min): "Your body needs three things daily to function well: good food (nutrition), movement (exercise), and rest (sleep). Let's explore what that looks like for rangatahi."
- Nutrition Breakdown (4 min): Present key points:
- What: Balanced diet with variety - vegetables, fruits, whole grains, protein, healthy fats
- Why: Fuel for energy, growth, brain function, immune system
- Teenager Needs: More calories than adults (2000-3000/day depending on activity), extra calcium/iron for growth
- Real Talk: "Healthy eating doesn't mean perfect. It's about making good choices most of the time and eating when hungry."
- Kai Māori: Traditional foods like kūmara, fish, seafood, native vegetables are nutrient-dense
- Hydration: 6-8 glasses of water daily, more if exercising
- Exercise Breakdown (4 min): Present key points:
- What: 60+ minutes of physical activity daily for teenagers
- Why: Strengthens heart/lungs, builds bones/muscles, improves mood, better sleep
- Types: Aerobic (running, swimming), strength (weights, push-ups), flexibility (yoga, stretching)
- Real Talk: "Exercise doesn't have to mean sports or gym. Walking, dancing, gardening, playing with pets - it all counts!"
- Māori Perspective: Traditional activities like waka ama, kapa haka, haka build fitness and cultural connection
- Sleep Breakdown (4 min): Present key points:
- What: 8-10 hours per night for teenagers (yes, really!)
- Why: Brain consolidates learning, body repairs/grows, hormones regulate, immune system strengthens
- Teenager Reality: Your brain is wired to stay up later and sleep in - that's biological, not laziness
- Sleep Hygiene: Dark room, no screens 30-60 min before bed, consistent schedule, cool temperature
- Real Talk: "Most teenagers are chronically sleep-deprived. This affects mood, learning, immune system, even decision-making."
- Quick Check (1 min): "Which of the Big 3 is hardest for you? Thumbs up for nutrition, sideways for exercise, down for sleep." (Quick class poll)
👥 Student Actions:
- Listen actively and take notes
- Ask clarifying questions
- Reflect on personal habits in each area
- Participate in quick poll
💬 Important Teaching Points:
- No shame/guilt: Frame as information to empower, not to judge current habits
- Barriers are real: Acknowledge that access to healthy food, safe exercise spaces, and sleep can be limited by family/economic factors
- Progress not perfection: Small improvements matter more than complete overhauls
- Individual differences: Bodies have different needs - what works for one person may not work for another
Activity 3: Physical Health Reality Check (15 minutes)
⏱️ 25-40 min🎯 Purpose:
Students honestly assess current habits and identify specific areas for growth
👩🏫 Teacher Instructions:
- Distribute Tracker (1 min): Give students Physical Wellbeing Tracker handout
- Model Honest Assessment (2 min): Show example:
- "For nutrition, I'm doing okay - I eat breakfast most days and have vegetables at dinner. But I drink too much soft drink and skip lunch when busy. I'd give myself 6/10."
- Emphasise: No judgment, just awareness
- Individual Assessment (10 min): Students complete tracker sections:
- Nutrition: Rate eating habits, water intake, meal regularity
- Exercise: Rate activity level, variety of movement, enjoyment
- Sleep: Rate hours of sleep, sleep quality, bedtime routine
- Overall Physical Health: Rate energy levels, illness frequency, body care
- Reflection Prompt (2 min): "Look at your ratings. Are you surprised by anything? Which area do you most want to improve?"
👥 Student Actions:
- Complete tracker honestly and thoughtfully
- Reflect on current habits without judgment
- Identify patterns and connections
- Keep assessment private unless choosing to share
💙 Pastoral Care Note:
As students work, circulate and observe (without reading over shoulders). Watch for:
- Students rating everything very low → Check in privately, offer support
- Students mentioning concerning behaviours (extreme dieting, over-exercising) → Follow up sensitively
- Students who seem distressed → Make time to talk after class
Have school counselor contact info and helpline numbers ready if needed.
Activity 4: Barriers & Solutions Workshop (15 minutes)
⏱️ 40-55 min🎯 Purpose:
Identify real barriers to physical wellbeing and brainstorm practical, realistic solutions
👩🏫 Teacher Instructions:
- Introduce Challenge (2 min): "Everyone knows exercise, sleep, and good food are important. But why is it hard to actually do them? Let's talk about real barriers and real solutions."
- Brainstorm Barriers (5 min): As a class, list common barriers on the board. Prompt as needed:
- Nutrition: Cost of healthy food, busy family schedules, lack of cooking skills, food deserts in neighbourhood, cultural food differences
- Exercise: Lack of time, no safe spaces to exercise, self-consciousness, disability or injury, no transport to facilities, expensive equipment/memberships
- Sleep: Homework load, family responsibilities, anxiety/stress, phone/social media, noisy/unsafe living situation, early school start times
- Small Group Problem-Solving (6 min): In groups of 3-4:
- Choose 2-3 barriers from the list that feel most relevant
- Brainstorm creative, realistic solutions
- Focus on what's in your control (not "schools should start later" but "I could try getting ready for bed 30 min earlier")
- Share Solutions (2 min): Quick popcorn sharing - groups call out their best solutions
👥 Student Actions:
- Contribute honestly to barrier discussion
- Think creatively about solutions in small groups
- Consider both individual and community-level changes
- Share ideas with the class
💬 Sample Solutions to Highlight:
- Nutrition on a budget: Seasonal vegetables, bulk buying, community gardens, learning simple cooking, water instead of soft drinks
- Exercise without gym: YouTube workout videos, walking/biking to school, dancing in room, playing with siblings/pets, taking stairs, active video games
- Sleep with homework: Time management, no homework in bed, communicate with teachers if overwhelmed, power naps, weekend catch-up (not ideal but realistic)
- Systemic barriers: Acknowledge some barriers need community/policy solutions - advocate for change while doing what you can individually
Activity 5: Goal Setting & Reflection (5 minutes)
⏱️ 55-60 min🎯 Purpose:
Set one realistic physical health goal and commit to action
👩🏫 Teacher Instructions:
- Introduce SMART Goals (1 min): Briefly explain: Specific, Measurable, Achievable, Relevant, Time-bound
- Model Goal-Setting (1 min):
- Bad goal: "Get healthier" (too vague)
- Good goal: "Drink 6 glasses of water every day this week" (specific, measurable, achievable, time-bound)
- Individual Goal-Setting (2 min): Students write one physical wellbeing goal for the next week in their tracker. Must include:
- What exactly will I do?
- How often?
- How will I know if I succeeded?
- Exit Ticket (1 min): "Share your goal with one other person - accountability partner!"
👥 Student Actions:
- Set one realistic, specific goal
- Write it down in tracker
- Share with a classmate for accountability
- Commit to trying for one week
📝 Good Goal Examples:
- "Go for a 20-minute walk 4 times this week"
- "Eat breakfast every school day this week"
- "Be in bed by 10pm on school nights this week"
- "Do 10 push-ups and 10 sit-ups every morning"
- "Try one new vegetable this week"
- "Put phone away 30 minutes before bed for 5 nights"
🏠 Homework / Extension
Required: Track Your Goal (Daily, 5-10 min/day)
For the next 7 days, track your physical wellbeing goal. Each day, write a quick note:
- Did you achieve your goal today? Yes/No/Partially
- What helped or got in the way?
- How did you feel physically?
Bring your tracker to next lesson to reflect on patterns.
Optional Extension 1: Food Diary (20 minutes)
Keep a food and drink diary for 2-3 days. Notice:
- What do you eat most often?
- When do you eat? (Meal times, snacking patterns)
- How do different foods make you feel?
- Are you eating when hungry or for other reasons? (boredom, stress, social)
No judgment - just observation and curiosity!
Optional Extension 2: Movement Challenge (Week-long)
Try a new form of movement this week you've never done before. Ideas:
- YouTube yoga/dance video
- Try a new sport or activity
- Go for a nature walk/hikoi
- Learn a cultural dance (haka, Samoan slap dance, etc.)
Reflect: How did it feel? Would you try it again?
