Balanced Health Essentials

i want to work on this informartion Good health Good health is not just the absence of disease or illness, it is a state of complete physical, mental and social well-being.

This means eating a balanced diet, getting regular exercise, avoiding tobacco and drugs and getting plenty of rest.

Our bodies are like machines that require a balance of protein, carbohydrates, fat, vitamins, minerals and water to stay in good working order.

Get the balance wrong and your health will suffer.

A balanced diet means eating only as many calories as you use during the day.

Any excess will be stored as fat if you eat more than you burn off.

Find out how exercise and diet are key to staying healthy.

How important is a balanced diet? The benefits of a balanced diet are:

a strong immune system to prevent and fight infections; a lower risk of certain types of cancers; lower blood pressure; a healthy weight; more energy; essential nutrients to support tissue growth.

What type of foods should I avoid? Many people do not buy and prepare fresh food, and it's easy to see why.

We are often short of time, and cheap, highly processed convenience food is always available.

However, convenience food has a negative impact on our health. Here are a few examples of this type of food:

junk food, like crisps and chocolate, is high in calories but low in nutritional value; fast food, such as hamburgers and fried chicken, is prepared and served quickly but is high in fat; convenience food, such as microwave ‘ready meals’, often has too much salt and sugar.

How important is staying active? Your body isn’t made to sit around.

If joints and muscles are to be kept in good, working order they need regular exercise.

If you stop walking, they'll stop working.

Your body finds it much easier to deal with threats such as sickness, injury, or the occasional sugary or fatty snack if you are active.

Exercise also helps you maintain a healthy attitude to problems and mental pressures.

You gain less body fat, tire less easily and feel better.

Exercise gives you greater flexibility and strength, prevents boredom and helps you sleep.

It also helps you find new friends and learn new skills.

Overview

This 35-minute lesson aims to deepen Year 8 students' understanding of what constitutes good health beyond the mere absence of illness, emphasising the importance of a balanced diet and regular exercise. The lesson aligns with the National Curriculum for England, focusing on personal health education within the broader PSHE (Personal, Social, Health and Economic education) statutory framework.

- Pupils should know:
  - How to maintain physical, mental and emotional health and wellbeing including healthy eating, fitness and exercise, and the benefits of rest and sleep.
  - How to make informed choices about health, diet and lifestyle and understand the consequences of unhealthy behaviours.
  - How to evaluate how reliable different sources of health information are.
Science (Key Stage 3 - Year 8)
- The components of a healthy diet.
- The impact of diet and exercise on the human body.

Learning Objectives

By the end of the session, students will be able to:

Define ‘good health’ as a state of complete physical, mental, and social wellbeing.
Identify the key components of a balanced diet and their functions within the body.
Explain the negative impact of processed and convenience foods on health.
Describe how regular exercise benefits physical and mental health.
Discuss ways to maintain good health through diet and activity choices.

Resources Needed

Whiteboard & markers
Projector or interactive whiteboard
Pre-prepared food labels or image cards (covering balanced and unhealthy foods)
Exercise cards with different physical activities
Student worksheets (balance diet planner and reflective questions)
Timer or stopwatch

Lesson Structure

1. Introduction (5 mins)

Starter question: “What does ‘good health’ mean to you?” – brainstorm ideas and write key words on the board.
Teacher introduces the definition of good health from the National Curriculum perspective.
Set the context: health as complete physical, mental, and social wellbeing — not just absence of illness.

2. Exploring Balanced Diet (10 mins)

Present and discuss the components of a balanced diet: protein, carbohydrates, fats, vitamins, minerals, water.
Activity: In pairs, students receive a selection of food label cards and sort them into ‘balanced’ and ‘not balanced’.
Discuss why certain foods (junk food, fast food, convenience food) are unhealthy: focus on calories, fats, sugars, salt.
Highlight the importance of eating calories only as needed to avoid fat storage and health problems.

3. Importance of Exercise (8 mins)

Teacher explains the benefits of exercise: muscle & joint health, mental wellbeing, energy levels, social benefits.
Quick class poll: What are their favourite physical activities?
Interactive station activity: Students rotate through quick ‘exercise challenge’ cards (e.g., 20 star jumps, 30-second wall sit) to experience the physical aspect and understand variety in exercise.
Discussion on how inactivity can negatively affect the body and mind.

4. Linking Diet and Exercise (7 mins)

Class brainstorm: “How do diet and exercise work together to keep us healthy?”
Students complete a short worksheet mapping how good nutrition and staying active support each other.
Reflection question: “What small change can you make this week to improve your health?”

5. Plenary and Assessment (5 mins)

Recap key points using a quick quiz (verbal or interactive tools).
Exit ticket: Each student shares one new thing they learned and one action they will try based on today’s lesson.
Teacher collects worksheets for informal assessment of understanding.

Differentiation

Support: Provide sentence starters and vocabulary banks for students who find writing difficult.
Challenge: Encourage higher-attaining students to explain how different nutrients affect specific body systems (e.g., immune system).
Sensory learners: Use visual food cards and physical exercises.
EAL learners: Pre-teach key vocabulary such as ‘nutrients,’ ‘immune system,’ and ‘convenience food’.

Extension Ideas

Homework: Keep a food and activity diary for 2 days to self-assess balance between diet and exercise.
Cross-curricular link to Science: Investigate the role of vitamins and minerals on growth and bodily functions.
Research project: Investigate local food outlets and assess their healthiness.

Teacher Reflection Prompts

Did students demonstrate clear understanding of the balanced diet components?
Which activities engaged students most and why?
Were students able to connect mental, social, and physical health aspects effectively?
How can exercise activities be adapted for mixed ability classes?

This lesson plan is designed to actively engage Year 8 learners in thinking critically about their own health, fostering both knowledge and positive personal choices inline with the National Curriculum’s goals for health and wellbeing education.
