Curriculum Area: Physical Education (A-level, Year 12, UK National Curriculum – Personal Development and Healthy Active Lifestyles)

---

Lesson Objectives

By the end of the lesson, students will:

1. Understand the roles of macronutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals) in maintaining physical health and wellness.
2. Analyse how inadequate nutrition impacts energy, physical performance, and susceptibility to diseases.
3. Develop critical thinking skills by evaluating the nutritional content of commonly consumed foods.
4. Explore the concept of a balanced diet and discuss practical strategies for improving eating habits.

Lesson Structure (60 Minutes)

1. Warm-Up Activity (5 Minutes)

Objective: Engage students, spark curiosity, and activate prior knowledge.

• Begin with a "food trivia warm-up." Write the following on the board:
  • "What is the difference between macronutrients and micronutrients?"
  • "What happens when your body doesn’t get enough vitamins or minerals?"
• Students provide quick shout-out answers, or if unsure, they write guesses on post-it notes.
• Transition to today’s topic: "Understanding Nutrition Basics."

2. Interactive Mini-Lecture (15 Minutes)

Objective: Introduce key concepts in an engaging way.

Step 1 – Macronutrients:

• Carbohydrates: Energy providers. Relate to sports performance (e.g., sprinters).
• Proteins: Muscle repair and growth. Connect to recovery in athletics (e.g., post-gym or competition).
• Fats: Sustained energy. Clarify the difference between healthy (unsaturated) and unhealthy (trans/saturated) fats.

Step 2 – Micronutrients:

• Discuss vitamins (e.g., Vitamin D and bone health) and minerals (e.g., iron and oxygen transport).

Teacher Tip: Use visual aids such as food models or images to show high-carb, protein-rich, and vitamin-filled foods. Bring a relatable, real-life angle by connecting food to sports/exercise outcomes.

3. Group Activity: Nutrient Analysis (20 Minutes)

Objective: Foster collaboration and apply theoretical knowledge.

1. Divide students into 4 groups (3 students per group). Assign each group a food category:

   • Group 1: Breakfast Foods
   • Group 2: Snacks
   • Group 3: Beverages
   • Group 4: Takeaway Meals

2. Provide laminated food labels or mock-up nutrition info (e.g., crisps, energy drinks, burgers, fruit smoothies).

3. Tasks:

   • Identify the macronutrients and key micronutrients on the label.
   • Discuss if the food is healthy or unhealthy. Why?
   • Suggest alternative, healthier options (e.g., swapping crisps for baked snacks).

4. Output: Groups create a “Quick Facts Sheet” on their category—one positive and one negative about each food.

4. Discussion: Nutritional Balance and Wellness (10 Minutes)

Objective: Debate and reflect on food choices critically.

• Facilitate a class discussion using the following questions:
  • "How does eating too much sugar or fat impact physical performance?"
  • "What would a balanced diet look like for an active teen your age?"
  • "Are there barriers to eating healthily? How can we address them?"

Extension: Highlight real-life concerns, e.g., food deserts, cost of fresh produce, and time constraints for busy students. Use these challenges to brainstorm creative, feasible solutions (e.g., meal prepping).

---

5. Cool-Down: Personal Reflection (5 Minutes)

Objective: Reinforce key takeaways and encourage self-awareness.

• Provide students with a worksheet titled "My Nutrition Plan".
  • Prompt: "Write THREE changes you can make to improve your eating habits based on what you’ve learned today."
  • Optional: Students share responses (voluntary).

Wrap up by previewing the next lesson: "Lesson 2: Meal Planning and Energy Needs."

---

Materials Needed

• Post-it notes
• Laminated food labels or printed mock nutrition info (variety of foods)
• Markers and posters (for group fact sheets)
• "My Nutrition Plan" reflection sheet (one per student)

---

Assessment Opportunities

• Observe group discussions for participation and understanding.
• Evaluate the fact sheets for accurate identification and analysis of nutrients.
• Review individual "My Nutrition Plan" worksheets for thoughtful reflections.

---

Differentiation

• Stretch: Challenge high-performing students to calculate caloric intake or research glycaemic index during the activity.
• Support: Pair students who need extra help with confident peers during group work. Use visual examples during the lecture to reinforce understanding.

---

Homework

Students are tasked with tracking their meals/snacks for 3 days using a simple food diary. Prompt: "Identify where you could improve balance in your diet and bring this to discuss in Lesson 2!"

Teacher's Reflection Notes

• Did students engage with the group activity?
• Did discussions reveal misconceptions about diet or health?
• How confident did students seem in applying their knowledge to real-life situations?
