Beginner10 pages • EnglishQuick Summary
The chapter 'Sunita in Space' from Class 5 EVS explores the experiences of astronaut Sunita Williams. It describes her life in space, highlighting the challenges and wonders she encountered like floating in zero gravity and seeing Earth from afar. The chapter also invites students to use their imagination to picture space and understand the concept of gravity through various thought experiments. Sunita's story inspires children to pursue their dreams no matter the obstacles.

Questions in Chapter
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?

Looking at 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?

Can you think why Sunita’s hair was standing?

Where are the lines, really! Sunita describes her view of the earth from the spaceship: “The earth looks so beautiful and amazing. We could watch it for hours, from the window of the spaceship. We could clearly see the curved shape of the earth.”

Additional Practice Questions
What would happen if you tried to pour a glass of water in Sunita's spacecraft?
mediumAnswer: In Sunita's spacecraft, attempting to pour a glass of water would cause the water to form blobs and float around due to the microgravity environment rather than pouring normally.
Explain why Sunita Williams' hair stands on end while in space.
easyAnswer: Sunita Williams' hair stands on end in space because of the absence of gravity which on Earth pulls everything down. In microgravity, hair floats just like other objects and hence stands upright.
Describe what Sunita Williams might have seen when she looked at Earth from space.
mediumAnswer: From space, Sunita Williams would see Earth as a whole, without visible lines dividing countries. The vast oceans, landmasses, and clouds are prominent features from that vantage point.
How would your weight change if you were in space, like Sunita Williams?
mediumAnswer: In space, you would feel weightless due to microgravity. On Earth, gravity gives us weight by pulling us down, but in space, this pull is much weaker, causing an experience of weightlessness.
Imagine your classroom as a spaceship orbiting Earth. What changes would you notice?
hardAnswer: You would float instead of walking; paper and pencils would need to be secured to prevent them from drifting away. Eating and drinking would involve capturing blobs of food and liquids.
Why can’t you see the lines that divide countries when looking at Earth from space?
easyAnswer: The lines dividing countries are human constructs on maps and not physical features; therefore, they are invisible from space where one sees Earth as a unified whole.
What are some of the challenges faced while doing everyday tasks in space?
mediumAnswer: Everyday tasks in space can be challenging due to the lack of gravity. Activities like eating require capturing floating food, water blobs must be handled carefully, and you must secure yourself to avoid drifting away.
What would Earth look like from the moon?
mediumAnswer: From the moon, Earth would appear as a bright, large object in space, marbled with swirls of clouds over blue oceans and brown-green land. It would reflect sunlight brightly.
How does the concept of gravity differ in space compared to Earth?
mediumAnswer: Gravity on Earth pulls objects downward, giving them weight and enabling objects to stay in place. In contrast, in space, the weaker gravitational pull results in objects and people floating.
