NCERT Solutions For Class 5 Evs Chapter 11 Sunita In Space - 2025-26
FAQs on NCERT Solutions For Class 5 Evs Chapter 11 Sunita In Space - 2025-26
1. How do the NCERT Solutions for Class 5 EVS Chapter 11 help in understanding the key concepts about space?
The NCERT Solutions for Class 5 EVS Chapter 11, 'Sunita in Space', provide clear, step-by-step answers to all textbook questions. They help students correctly understand fundamental concepts like gravity, the shape of the Earth, life in a spaceship, and celestial bodies. By following these solutions, students can grasp the scientific principles in a simple manner, as required by the CBSE 2025-26 syllabus.
2. According to the NCERT textbook, why did Sunita Williams' hair keep standing in the spaceship?
In the spaceship, Sunita Williams was in an environment with almost no gravity. The textbook explains that on Earth, the force of gravity pulls everything, including our hair, downwards. In space, without this pull, things float. Therefore, her hair did not hang down but floated and appeared to be standing up. This is a key observation to understand the concept of zero gravity.
3. What is the correct method to explain the difference between a globe and the actual Earth, as seen from space?
The correct explanation, as per Chapter 11, is that the globe is a model of the Earth. From space, Sunita Williams could see land and sea but not the lines that divide countries and states. The solution highlights this key difference:
- The globe has lines (borders) drawn on it by humans to show different countries.
- The actual Earth, when viewed from space, is one whole planet without any such lines. It only shows natural divisions like landmasses and water bodies.
4. Why do we not float around on Earth like Sunita did in space?
This is because of a powerful, invisible force on Earth called gravity. Earth's gravity constantly pulls everything towards its centre. This pull is what keeps our feet firmly on the ground, makes a ball fall back down when thrown up, and prevents us from floating away. In space, this gravitational pull is extremely weak, which is why astronauts and objects float freely inside their spaceship.
5. What difficulties did Sunita Williams face while doing daily tasks like eating in space?
The NCERT chapter describes several challenges of living in a spaceship. For eating, since there is no gravity, food does not stay on a plate. Astronauts have to catch floating blobs of food. Similarly, water does not stay in a glass but floats as blobs. To wash their face, they have to catch these blobs with a paper towel. These examples show how much daily life depends on Earth's gravity.
6. If there are no actual borders on Earth from space, why is it important to learn about them on maps and globes?
While space shows us one unified planet, the lines on maps and globes are essential for our life on Earth. These imaginary lines, or borders, are created by people to:
- Organise the world into different countries and states for governance and administration.
- Help us understand geography, locations, and distances between places.
- Define different cultures, languages, and systems.
7. As discussed in Chapter 11, what festivals are related to the moon, and what do we learn from observing it?
The chapter encourages students to observe the moon and its phases. Several festivals in India are linked to the lunar cycle. Some examples mentioned or related to the chapter's theme are:
- Karwa Chauth, where the moon is sighted.
- Eid, which is celebrated after sighting the new moon.
- Buddha Purnima and Guru Nanak Jayanti, which are celebrated on a full moon night.
8. How does solving the questions in 'Sunita in Space' help us better appreciate our life on Earth?
By solving the problems in this chapter, we learn about the challenges of living without gravity. When we understand that even simple acts like drinking water, eating food, or combing hair are difficult in space, we begin to appreciate the unique conditions on Earth that make life comfortable. The concept of Earth’s pull (gravity) is no longer just a fact but a force we can be thankful for. It highlights the importance of protecting our planet, the only place perfectly suited for us.
