We Breathe Air
NCERT anchor: NCERT Looking Around Class 1 — Theme: Air (breathing)
What you'll learn
- We breathe air through nose into lungs — all the time.
- Clean air keeps us healthy; cover nose near dust or smoke.
- Hold breath briefly — feel need for air (activity with teacher).
Key concepts
1. Air is invisible but real
Level 1 (Verbal): Feel breeze on face — air is there.
Level 2 (Symbolic): Nose → windpipe → lungs (simple body map).
Visual: Diagram of person breathing in/out.
2. Breathing in and out
Verbal: In — chest expands; out — chest goes down.
Visual: Pinwheel near mouth moves when you blow.
3. Clean air
Verbal: Trees help clean air; avoid smoke from burning waste.
Worked example
Breathing after running in PE class
Step 1 — Run gentle lap → feel heart fast.
Step 2 — Breathe **in** through nose — chest rises.
Step 3 — Breathe **out** — chest falls.
Step 4 — Need **more air** after exercise — normal!
Answer: lungs take air in and out; exercise needs more.
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| We breathe oxygen only at Class 1 depth | Say 'air' simply | Air has what lungs need — detail in later grades |
| Hold breath forever possible | Body forces breathe | Short hold OK in game; then breathe |
| Nose no use — mouth only | Nose filters dust | Prefer nose breathing when healthy |
Quick check
- Do we breathe even while sleeping?
- Which body part fills with air — lungs or stomach?
- Why breathe through nose near dusty road?
- Stretch: Why do you breathe faster after cricket?
Revision tip: Three calm breaths before class test — in through nose, out slow.
