Questions and Solutions

Question 1

What do you think?
  • If the earth is round like a globe, how is it that we do not fall off?
Do the people in Argentina stand upside down?
Solution: We do not fall off the Earth because of a force called gravity. Gravity is like an invisible pull that the Earth has, which attracts everything towards its center. No matter where you are on Earth, whether it's the North Pole, the South Pole, or even a place like Argentina, gravity pulls you towards the center of the Earth. This is why people in Argentina do not stand upside down; they are pulled towards the Earth's center, just like everyone else. Imagine the Earth is a giant magnet, and we are small metal pieces; the magnet pulls us towards it, keeping us stuck to its surface.

Question 2

Look at the photogram:

Can you think why 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?
Solution: Sunita's hair was standing in the photograph because she was in a spaceship, far away from Earth. In space, there is very little gravity, which is the force that pulls things down towards the Earth. Without this strong pull, her hair, like other light objects, was floating and not falling down, making it look like it was standing on its own.

Regarding the photographs and dates:

  • 9-12-2006: Sunita and her friends started their journey in the spaceship.
  • 11-12-2006: Two photographs show Sunita and her friend floating in the spaceship, and another shows food packets flying around, indicating the effect of microgravity.
  • 13-12-2006: A photograph shows Sunita continuing her work with ease, with her hair still not falling down, demonstrating the ongoing effect of weightlessness.
  • 16-12-2006: (The description seems incomplete in the source, but it likely shows further activities or observations from the space mission.)

Common mistakes

  • Confusing the absence of gravity with a complete lack of force.
  • Not understanding that gravity is what keeps us on Earth.
  • Difficulty visualizing how objects behave in microgravity.

Revision tips

  • Imagine yourself in space and how you would feel and move.
  • Draw pictures to show how things float in a spaceship.
  • Discuss with friends why gravity is important for us on Earth.

Practice MCQs

Q1. Why does Sunita's hair stand on end in the spaceship?

Q2. What is the main reason people don't fall off the Earth?

Q3. What happens to food packets in a spaceship without gravity?

Q4. Where does Sunita Williams travel?

Frequently asked questions

What is the main topic of Chapter 11 for Class 5 EVS?

Chapter 11, 'Sunita in Space,' focuses on the experiences of an astronaut, Sunita Williams, and explains the effects of being in space, such as floating due to the absence of gravity.

Why is gravity important according to these solutions?

Gravity is the force that pulls everything towards the center of the Earth, which is why we and other objects stay on the ground and do not fall off.

How do these NCERT Solutions help students?

These solutions provide clear, rewritten answers to the questions in Chapter 11, helping students understand complex concepts like microgravity and space travel in an age-appropriate manner for better learning and exam preparation.

What happens to objects in a spaceship?

In a spaceship, where gravity is very weak (microgravity), objects like hair, food, and people tend to float around instead of staying in one place or falling down.
