15.4 GOING TO SPACE

Learning objective/Aim –The child will be able to know about going to

space.

Note

 The area outside the earth is the space. In space, there are various
celestial objects like planets, meteors, stars etc. These meteors are

what ‘fall’ from the sky. Space is a quiet place. No one can hear

you in space, no matter how hard you scream.

 There is no air in space it is just like a vacuum, in this empty space

neither can sound waves travel nor could the sunlight be

scattered. We cannot sit or walk around we can only float in

space.
 Not only this, but they also have to catch the floating packets

of water and food in the spaceship! This is because of the lack of

the gravitational pull in space. On earth, when we throw

something up it comes down because of gravitational force.

 However, in space, there is no such force. Therefore, things

float. Note: an astronaut is properly trained to travel to space by

spacecraft.

 There are many astronauts who have been to space.

From India, we have great astronauts who have travelled up to

space in a spacecraft. Some of them include KalpanaChawla and

Rakesh Sharma.

Learning outcome –The children will be able to speak about the
space.
