00:00Air

00:03On your marks, get set, go!

00:08Sam uncle signals the little bikers to start the race.

00:14Nine of them are on the truck immediately.

00:18Armaan is struggling. His cycle refuses to move.

00:23Arzu and Mummy are surprised.

00:27He had learnt to balance himself quite well and had practiced so hard for the race.

00:34Mummy goes to see what went wrong.

00:37Armaan was sitting on his cycle trying hard to move.

00:41He had tears in his eyes.

00:44As soon as he saw Mummy, he started crying.

00:48Mummy hugged him first then looked at his cycle. It had a flat tyre.

00:53Oh! The back tyre is flat. That is why it is not moving.

01:00Armaan looked at his mother.

01:03Flat tyre? What does that mean, mom?

01:06Mummy then explained to him that the tyre has air in it.

01:12All tyres have air in them. Without air, they are of no use.

01:18Wiping his tears, she drags the cycle and takes it to a cycle repair shop in the neighborhood market.

01:27Armaan watches as the air is filled in and the tyre expands slowly.

01:35Mama, this is just like a balloon. When daddy blows into the balloon, it also becomes big.

01:43Mummy then explains to him.

01:46Mummy then explains to him that this is air.

01:51When air is blown into a balloon or tyre, it expands and only then it becomes useful.

02:01Air is everywhere. We cannot see it as it has no color.

02:08When it is still, we can neither see it nor feel it.

02:13But we are alive only because of air.

02:18We breathe air all the time. We breathe through our nose.

02:24Rho A

02:27Rho B

02:30Rho A has living things.

02:34Rho B has non-living things.

02:37What is the one common thing between Rho A and Rho B?

02:43Yes, they both need air.

02:48Rho A needs air to breathe.

02:53Living things will die if they don't get air.

02:59Plants, animals and human beings need air to live.

03:04The non-living things in Rho B need air to become useful.

03:11A balloon gives us pleasure only when it is filled with air.

03:17A tyre is of no use without air.

03:22And we cannot play with a flat football.

03:26When you fill air in them, they become big. They expand.

03:33This shows that air occupies space.

03:39A candle needs air to burn.

03:43When we cover a burning candle with a glass jar, the candle stops burning.

03:50When we cover a burning candle with a glass jar, the candle stops burning.

03:57This shows that air is needed for burning.

04:02Which of these will weigh more?

04:06Yes, the inflated tyre, balloon and football weigh more.

04:14This shows that air has weight.

04:19When the air moves or we make the air move, we can feel it.

04:27Moving air is called wind.

04:31Sometimes we feel it strongly.

04:36Sometimes we feel it gently.

04:40Armaan, Arzu and Ginger are visiting their grandparents who live near a big lake far away from the city.

04:52The children are very excited as there is so much open space here.

04:59As soon as they wake up, they run to the huge grounds overlooking the lake.

05:06It is a very pleasant day.

05:10Many things such as the sailing boat in the lake,

05:15the moving windmills make them feel the presence of wind.

05:22Armaan is happy as he can fly the kite high up in the sky.

05:29Now you know.

05:32Air is everywhere.

05:35We cannot see it as it is colourless.

05:40All living things need air to live.

05:46Air occupies space.

05:50Air has weight.

05:54Air is needed for burning.

05:59Moving air is called wind.

06:02Sometimes we feel it strongly.

06:05Sometimes we feel it gently.

06:09We should try to keep the air as clean as possible.
