How Breathing Works means tracing air through nose/mouth to lungs, taking oxygen in and breathing carbon dioxide out. We will practise once together, then check a fresh example.
Spend about 12 minutes tracing the breathing path, matching oxygen/CO₂, then checking one fresh fact.

Check understanding
- Trace the path of air: nose/mouth → windpipe → lungs
- State that lungs take oxygen from the air, which the body needs
- State that we breathe out carbon dioxide, which the body doesn't need
“After running around, can your child notice their faster breathing and explain that their lungs are taking in air that the body needs?”
