- If the earth is round like a globe, how is it that we do not fall off?
Ans. We do not fall off the earth because the gravitational force of the earth attracts everything towards itself.
- Do the people in Argentina stand upside down?
Ans. No, the people in Argentina are not standing upside down. They are also standing upright. There is no ‘up’ and ‘down’ on the earth. It is relative.
Look at the Photograph and Write Page No. 166
- Can you think why Sunita’s hair was standing?
Ans. On the earth, our hair remains in a downward direction due to the gravitational force of the earth. There is no gravity in space and so Sunita’s hair was standing.
- Look at Sunita’s photographs and the dates written on each of them. Write what all is happening and when?
|2006-12-09||The spacecraft is taking off.|

Classroom Becomes a Spaceship Page No. 166
- Close your eyes. Imagine that your class is a spaceship. Zooo…m in 10 minutes you have entered space. Your spaceship is now going around the earth. Now say:
a) Are you able to sit at one place?
Ans. No, I am not able to sit at one place. Everyone is floating in the spacecraft because there is no gravity in space.
b) What about your hair?
Ans. My hair keeps standing up.
c) Oh, look…where are your bags and books going?
Ans. My bags and books are also floating in the spaceship.
d) What is your teacher doing? Where is her chalk?
Ans. My teacher is also floating in the spaceship and she is trying to catch the chalk which is also floating inside the spaceship.
e) How did you eat your food during the break? How did you drink water? What happened to the ball that you threw up?
Ans. We have to grab the food items floating in the air. The water is floating in the form of blobs and we had to suck them. The ball which I threw up is also floating.
Isn’t it amazing? Page No. 168
- Can you now say why Sunita’s hair kept standing?
Ans. It is due to the absence of gravity in the space Sunita’s hair kept standing.
- Think about why water flows downwards on any slope. On the mountains, too water flows downwards, not upwards.
Ans. The earth attracts everything towards itself with a fore called gravitational force, It is due to the earth’s gravitational force the water flows down the mountain.
Magic 1 – A tiny paper races a coin
Take a 5 rupee coin and a small piece of paper. The paper should be about one-fourth the size of the coin.
- Hold the coin in one hand and the paper in the other. Drop them at the same time. What happened?
- Now place the tiny paper on the coin and drop them. What happened this time? Surprised!
Ans. In the first scenario when the coin and the paper were dropped separately, the coin reaches the ground faster than the paper.
In the second scenario when a tiny piece of paper is placed on the coin and both were dropped together, both reach the ground at the same time.
Magic 2 – A mouse lifts an elephant
To play this you will need a small stone, a bigger stone (lemon-sized), a thick roll of paper (which can be made with layers of paper), a mouse and an elephant made of paper.
- Take a string about 2 feet long.
- At one end of the string tie the small stone. Stick or tie the mouse to the stone.
- Put the string into the roll of paper.
- At the other end of the string tie the bigger stone and stick the elephant.
- Hold the roll of paper and move your hand to rotate the small stone.
- Who is pulling whom? You will be surprised! The mouse lifts the elephant!
How did this magic happen?
Ans. The rotation of the small stone i.e., the mouse generates a force due to which the bigger stone i.e., the elephant is being pulled up.

What we have Learnt Page No. 173
- Why do children always slide down the slide and not slide up? If this slide were there in Sunita’s spacecraft, would children slide like this? Why?
Ans. The children always slide down the slide due to the gravitational force of the earth. If this slide were there in Sunita’s spacecraft, they would not have been able to slide due to the absence of gravity. They would have floated in the spacecraft.
- Why do we see stars mostly at night?
Ans. The stars have dim light which is not visible during the daytime due to the much brighter light of the sun. At night there is no sunlight so we can see the stars in the night.
- Looking at the earth from space, Sunita said, “Different countries cannot be seen as separate from here. These lines are on paper. They are made by us”. What do you understand by this?
Ans. We cannot identify different countries from space because no boundaries are there on the earth that separate different countries. These lines and boundaries are created by human beings for their understanding.
