Uses
Uses of Air
NCERT anchor: NCERT Looking Around Class 1 — Theme: Air (air helps us live)
What you'll learn
- Air for breathing, burning a diya/candle, and turning windmills.
- Trees give oxygen and clean air — plant and care for saplings.
- Balloons, tyres, and footballs hold air inside (simple).
Key concepts
1. Breathing (main use)
Level 1 (Verbal): Living things need air in lungs — link to We Breathe note.
Level 2 (Symbolic): No air → cannot live long (simple, serious).
Visual: Person + tree exchanging air (picture chart).
2. Burning needs air
Verbal: Diya flame needs air; cover with glass → flame goes out (demo with teacher).
Visual: Candle and match — adult only.
3. Windmills and trees
Wind turns mill; trees clean air and give shade at school assembly.
Worked example
Diya on Diwali and trees in school yard
Step 1 — Light diya → flame needs **air** to burn.
Step 2 — Cover briefly with jar (teacher) → flame dies → air needed.
Step 3 — Trees nearby → fresh air for breathing.
Step 4 — Say thank you to trees on Van Mahotsav.
Answer: air for fire and breathing; trees help clean air.
Common mistakes
| Mistake | Why | Fix |
|---|---|---|
| Fire needs only match, not air | Air required | Oxygen in air supports burning — simple wording |
| Trees not related to air | Trees release oxygen | Plant one sapling if possible |
| Air has no uses | Many uses | List breathe, burn, wind power |
Quick check
- Why does a candle go out in a closed jar?
- Name one use of air besides breathing.
- How do trees help air?
- Stretch: Why is a football hard when full of air and soft when flat?
Revision tip: Link three uses: breathe, burn (with adult), wind — say one example each.
