Chapter 5 : Air around us

We cannot see air. It has no colour and no smell. But we can feel air and see what it can do!

• What makes the beach ball float?

• What helps the kite fly?

 

• Why can't this tyre work?

All about air

The air from a balloon can only move your hair. However, if air moves faster, it can move a kite or sway a tree!
Moving air is called wind
Air is light. It makes your beach ball float on water.
Air has no fixed shape. It fills up a container and takes the shape of that container.

Uses of air and wind
Air is another basic need for all living things! We breathe in air to stay alive.

Water plants and animals take in air from water.

How we breathe

 

Do you breathe faster when you exercise?

When you exercise, you need more air. So, you breathe faster than when you are resting.
