Importance of Exercise

Understanding the importance of exercise for human health, exploring different types of physical activity.

• National Curriculum Attainment Targets
• KS1: Science - Animals, Including Humans

About This Topic

Exercise supports human health by strengthening muscles and bones, improving circulation, and aiding growth. Year 2 students learn that activities like running, cycling, and dancing increase heart rate and breathing, which deliver more oxygen to the body. They also discover mental benefits, such as reduced stress and better focus, by comparing active play to sedentary tasks like screen time.

This topic aligns with the KS1 Animals, Including Humans strand, building on prior knowledge of basic needs. Students observe personal changes during exercise, record data on energy levels, and discuss how daily movement prevents health issues like obesity. Key skills include comparing effects of activities and designing simple routines, promoting scientific thinking and self-awareness.

Active learning suits this topic perfectly. When children take their pulses, try movement circuits, or create group exercise plans, they connect abstract benefits to real sensations. Peer feedback during sharing reinforces understanding and motivates healthy habits.

Key Questions

1. Explain how exercise benefits our bodies and minds.
2. Compare the effects of active play versus sedentary activities.
3. Design a simple exercise routine for a healthy day.

Learning Objectives

• Compare the impact of two different physical activities on heart rate and breathing.
• Explain how regular exercise contributes to stronger muscles and bones.
• Design a balanced daily exercise routine for a child, including at least three different types of activities.
• Identify the mental benefits of physical activity, such as improved mood and focus.

Before You Start

Body Parts and Their Functions

Why: Students need to know basic body parts like heart and muscles to understand how exercise affects them.

Living Things and Their Needs

Why: Understanding that humans, like other animals, need food, water, and air provides a foundation for understanding the need for exercise.

Key Vocabulary

Circulation	The movement of blood around the body, carrying oxygen and nutrients to muscles and organs.
Sedentary	An activity that involves sitting or lying down with very little movement, such as watching television or playing computer games.
Aerobic Exercise	Physical activity that increases heart rate and breathing for a sustained period, like running or swimming.
Muscle Strength	The ability of muscles to exert force, which is improved through activities like climbing or lifting.

Watch Out for These Misconceptions

Common Misconception

Exercise is only for fit children or athletes.

What to Teach Instead

All children benefit from regular play, regardless of skill. Hands-on circuits let every student feel improvements in strength and energy, building confidence through personal success and group encouragement.

Common Misconception

Exercise always makes you tired and out of breath forever.

What to Teach Instead

Short bursts energise and improve stamina over time. Pulse checks before and after activities show quick recovery, helping students revise ideas through repeated observation and discussion.

Common Misconception

Exercise only affects the body, not the mind.

What to Teach Instead

Mood and focus improve with movement. Comparing feelings during active play versus sitting reveals links, with peer sharing clarifying how endorphins work in simple terms.

Active Learning Ideas

Pulse Check Challenge: Before and After

Students measure resting pulse by counting beats for 15 seconds, then do 20 star jumps and re-measure. Record results on charts and discuss changes. Share findings in pairs to identify patterns.

Movement Stations: Circuit Training

Set up stations with skipping, balancing, and throwing beanbags. Groups rotate every 3 minutes, noting how each feels on body and mood. Conclude with a class vote on favourites.

35 min·Small Groups

Routine Design: Healthy Day Planner

In pairs, draw a daily timetable including exercise slots like morning jogs or play breaks. Present to class, explaining benefits over sedentary options. Vote on best ideas for school use.

Active vs Sedentary: Freeze Dance Debate

Play music for dance, then freeze for sedentary mime. Students note body feelings each time. Discuss in whole class why movement feels better.

Real-World Connections

• Physiotherapists help people recover from injuries by designing specific exercise programs to rebuild muscle strength and improve circulation.
• Sports coaches at local clubs like a junior football team plan training sessions that include warm-ups, skill drills, and cool-downs to improve players' fitness and prevent injuries.
• Playground designers create spaces with climbing frames and open areas to encourage active play, helping children meet their daily exercise recommendations.

Assessment Ideas

Quick Check

Ask students to hold their wrist and count their pulse for 30 seconds. Then, have them do 10 star jumps. Ask them to count their pulse again for 30 seconds and record both numbers. Prompt: 'What happened to your pulse after exercising, and why?'

Exit Ticket

Give each student a card with two boxes. In the first box, they draw a picture of an active game. In the second box, they draw a picture of a sedentary activity. Prompt: 'Write one sentence explaining which activity is better for your body and why.'

Discussion Prompt

Pose the question: 'Imagine you have one hour of free time after school. How would you spend it to be healthy and happy?' Facilitate a class discussion where students share their ideas, comparing different types of exercise and their benefits.

Frequently Asked Questions

How do I teach Year 2 students the benefits of exercise?

Use simple observations of heart rate and breathing changes during play. Link to daily life by tracking energy after active breaks versus screen time. Design routines together to make benefits personal and relevant to their routines.

What activities show exercise effects on body and mind?

Incorporate pulse checks, star jumps, and mood journals before and after movement. Circuits with varied activities highlight physical changes, while class discussions reveal mental boosts like happier feelings and better concentration.

How can active learning help teach exercise importance?

Active methods like movement stations and routine design let students experience benefits directly, such as faster pulses and improved mood. Group rotations build collaboration, while data recording turns sensations into evidence, making concepts stick through doing and sharing.

How to compare active play and sedentary activities in class?

Alternate dance with seated tasks, having students rate energy and focus each time. Charts visualise differences, and debates encourage explaining why movement wins, tying to health outcomes like stronger hearts.
