(CBSE Class 6 Science – Curiosity Book)
1. What is Science?
Answer:
Science is a way of thinking, observing and doing things to understand the world around us. It helps us ask questions, explore our surroundings and find out how things work.
2. Why is curiosity important in science?
Answer:
Curiosity makes us ask questions like “How?” and “Why?”. These questions lead to observations, experiments and discoveries. Without curiosity, we would not feel the need to explore or learn new things.
3. Give two examples that show science is everywhere.
Answer:
- Watching a flower bloom and wondering how it knows when to open.
- Observing how water changes into ice when cooled and into steam when heated.
4. Why is science compared to a giant jigsaw puzzle?
Answer:
Science is compared to a jigsaw puzzle because every new discovery adds a new piece to our understanding of the world. As we learn more, we realise there is still more to discover and understand.
5. What makes planet Earth special according to the chapter?
Answer:
Planet Earth is the only known planet that supports life. It has a suitable environment, air, water, soil and climate that allow plants, animals and humans to live and grow.
6. Why do we need food and water to survive?
Answer:
Food gives us energy to grow and stay healthy, while water helps our body function properly. Without food and water, living organisms cannot survive.
7. Give two examples of changes in water mentioned in the chapter.
Answer:
- Water freezes and becomes ice when cooled.
- Water boils and becomes steam when heated.
8. What is the scientific method?
Answer:
The scientific method is a step-by-step process used to find answers. It includes:
- Observing something
- Asking a question
- Making a guess (hypothesis)
- Testing the guess through experiments or observations
- Analysing the results
9. How does the example of a pen stopping help us understand the scientific method?
Answer:
When a pen stops writing, we first ask why, then guess a reason (like ink is over), and then test it by opening the pen. If the guess is wrong, we try another guess. This is exactly how scientists work.
10. Who is a scientist?
Answer:
A scientist is a person who uses the scientific method to observe, question, experiment and discover new things. But anyone who follows this method—even in daily life—is also like a scientist.
11. Give one example from daily life where someone uses a scientific method.
Answer:
An electrician checks why a bulb is not working.
He observes the problem, thinks of possible reasons (bulb fuse, switch problem), and tests each one. This is using the scientific method.
12. Why is it important to work together in science?
Answer:
Scientists often work in teams to share ideas, test results, solve complex problems and make new discoveries. Teamwork makes scientific work faster and more accurate.
13. What should we do if we cannot find an answer to our question?
Answer:
We should ask friends, teachers or others for help. Science becomes easier and more enjoyable when we explore and discover things together.
14. What does the line “To be a wise person, you must be a ‘whys’ person” mean?
Answer:
It means a wise person always asks “Why?” about things. Asking questions helps us understand the world better and learn more—this is the spirit of science.
15. What is the main message of this chapter?
Answer:
The chapter encourages us to be curious, ask questions, observe our surroundings and enjoy discovering the wonders of science. It inspires students to begin an exciting journey of learning science.
