Air Around Us

Class 2

🎯 Learning Objectives

📖 Let Us Begin!

Can you see air? No! But can you feel it? Yes! When the wind blows, you can feel air on your face.

Air is all around us. We breathe air every second. Without air, we cannot live.

Let us learn about the air around us!

Air Is Everywhere

Air is all around us. It is in our room, in the garden, in the sky, and even under water.

We cannot see air. We cannot smell clean air. But we can feel air when it moves.

How do we know air is there?

Blow into your hand. You can feel the air! Blow up a balloon. The balloon gets big because of air inside it. Shake a fan near your face. You feel the moving air.

Ravi blew up a balloon. When he let it go, the air came out and the balloon flew around the room. Air was inside the balloon!

We Need Air to Breathe

All living things need air to breathe. People, animals, and plants all need air.

When we breathe in, we take in air. When we breathe out, we let out air. We breathe about 15 to 20 times every minute!

If we hold our breath, we feel uncomfortable very quickly. This shows how important air is.

Wind

When air moves, it is called wind. Wind can be gentle or strong.

A gentle wind is called a breeze. It feels nice on a hot day. A strong wind can blow away leaves and papers.

Wind helps dry our clothes. Wind helps boats sail on water. Wind turns windmills to make electricity.

Keeping Air Clean

Clean air is good for us. Dirty air (pollution) can make us sick.

Air gets dirty when: smoke comes from cars and factories, people burn garbage, and dust rises from roads.

We can keep air clean by: planting more trees, not burning garbage, and using less smoke-making things.

Trees are our best friends! They take in dirty air and give out clean, fresh air. Let us plant more trees.
