Fuel For Life

Overview

In this 55-minute Physical Education lesson, students explore how good nutrition supports health, performance, and lifelong wellbeing. Students connect nutrition choices to the body’s needs by learning macros and micros, evaluating a healthy day of eating, and applying the 80/20 rule.

Learning intentions

• Students will explain why good nutrition is important for energy, recovery, and overall health.
• Students will define macronutrients and give examples and functions (carbohydrates, fats, protein).
• Students will define micronutrients and give examples and functions (vitamins and minerals).
• Students will design and justify an example day of eating using nutrition principles.
• Students will apply the 80/20 rule to real-life eating patterns.

Success criteria

• I can explain at least three reasons good nutrition supports my body and activity levels.
• I can correctly identify macronutrients, give examples, and explain what each does in the body.
• I can correctly identify micronutrients, give examples, and explain how they support body systems.
• I can justify a sample day of eating and explain how the 80/20 rule helps balance “good” and “sometimes” foods.

Curriculum links

• Health and Physical Education: Students develop knowledge to make informed decisions that support wellbeing and physical activity.
• Health and Physical Education: Students investigate how food and nutrition affect the body, performance, and health.
• NCEA-aligned learning focus (informing assessment literacy): using evidence-based reasoning about nutrition choices and their effects on the body.

Lesson structure (55 minutes)

1. 0–5 min · Starter (Question prompt). Teacher writes: “What helps you perform better—energy, recovery, or focus—and why?” Students quick-write 2–3 reasons, then share one with a partner.
2. 5–15 min · Direct teach (Why nutrition matters). Teacher explains links between nutrition and: energy for activity, recovery after exercise, concentration, growth, and long-term health; students take short notes under headings: Energy, Recovery, Health.
3. 15–25 min · Macros mini-lesson (Carbs, fats, protein). Teacher defines macronutrients as nutrients needed in larger amounts; models examples and functions:

• Carbohydrates: main fuel source (especially for higher-intensity activity)
• Protein: repair and build body tissues (muscle recovery)
• Fats: energy storage, hormone support, and absorbing some vitamins Students complete a quick “Match and explain” task: match each macro to a function, then write one example food for each.

4. 25–33 min · Micros mini-lesson (Vitamins and minerals). Teacher defines micronutrients as nutrients needed in smaller amounts that still support key body processes; gives examples and functions:

• Iron: oxygen transport
• Calcium: strong bones and teeth
• Vitamin C: immune support and tissue repair Students label a provided table with examples and functions (at least two micros identified correctly).

5. 33–44 min · Healthy day (Reasoning activity). Teacher gives students a template for an “Example day of eating” with meals/snacks (breakfast, lunch, snack, dinner, optional treat). Students plan a day using a “balance check”: include carbs for energy, protein for recovery/growth, some fats for hormones/satiety, and at least 3 different micronutrient-rich foods across the day. Students must write brief reasons for 3 choices (e.g., “I chose yoghurt for protein and calcium,” “I chose fruit for vitamin C and quick energy”).
6. 44–50 min · 80/20 rule (Apply to choices). Teacher explains the 80/20 rule: most meals (about 80%) are nutrient-dense to support health and performance; the remaining 20% allows flexibility with “sometimes” foods without guilt, still fitting a balanced lifestyle. Students answer: “Where would 80% foods and 20% foods fit in the day you planned?” Then they revise one meal/snack if needed.
7. 50–55 min · Exit ticket (Check understanding). Students respond to three questions:

• Define macro and micro in one sentence each.
• List one function of each macro (carbs/fats/protein).
• Give one example of how you applied the 80/20 rule.

Resources

• Nutrition notes slide/handout with headings: Macros, Micros, 80/20 rule
• “Match and explain” worksheet (macros to functions; space for examples)
• Micronutrient table (iron, calcium, vitamin C plus 1–2 student-selected options)
• “Example day of eating” template with meal sections and reason lines
• Coloured pens/highlighters for coding macros (carb/protein/fat) and micros (vitamin/mineral)
• Timer for structured tasks
• Optional: class “food card” set for discussion (if available)

Assessment

• Formative checks: teacher circulates during macro matching and micronutrient table completion for accuracy and correct definitions.
• Formative checks: review students’ “healthy day” reasons to ensure they link food choices to nutrient functions.
• Exit ticket marking: quick scoring for macro/micro definitions, correct functions, and a clear 80/20 application.

Differentiation

• Support: provide sentence starters for definitions and reasons (e.g., “Macronutrients are… They help my body by…”; “I chose ___ because it provides ___ which supports…”).
• Support: offer a “bank” of food examples grouped by macro/micro categories for students who need ideas.
• Extension: challenge students to adjust their sample day so that it supports a specific goal (e.g., improving recovery after sport, boosting energy for training) while still using the 80/20 rule.
• EAL/SEN: allow drawing or short label answers in worksheets (e.g., icons for vitamins/minerals) paired with teacher prompts to confirm understanding.
