How We Breathe: The Respiratory System
Year 5 Science Understanding how our lungs work Exploring the amazing journey of air through our body
WALT (We Are Learning To)
Identify the main parts of the respiratory system Explain how air travels through our body when we breathe Understand the job of each part in helping us breathe Use scientific vocabulary to describe breathing
Nose and Mouth: The Air Entrance
Air enters our body through our nose or mouth Nose hairs filter out dust and germs Nose warms and moistens the air Mouth can help when we need more air quickly
Trachea: The Air Highway
The trachea is also called the windpipe It's a tube that carries air to the lungs Made of strong rings to keep it open About as wide as your thumb
Breathing Investigation Activity
Place one hand on your chest, one on your belly Breathe normally and notice which hand moves more Take a deep breath - what happens now? Partner up and observe each other breathing
Lungs and Bronchi: The Air Processors
{"left":"Lungs are like two big spongy balloons in your chest\nThe left lung is smaller to make room for your heart","right":"Bronchi are tubes that branch inside each lung\nLike an upside-down tree with many branches"}
Alveoli and Diaphragm: The Tiny Workers
Alveoli are tiny air sacs at the end of bronchi There are millions of them in each lung They swap oxygen for carbon dioxide The diaphragm is a muscle that helps us breathe by moving up and down
Success Criteria - Can You Do This?
Can you name the 6 main parts of the respiratory system? Can you explain the journey air takes through your body? Can you describe what each part does to help you breathe? Can you use scientific words like trachea, alveoli, and diaphragm correctly?
