2. What is the most important quality needed to learn science?

Answer: Curiosity.

3. What does curiosity make us do?

Answer: It makes us ask questions and explore our surroundings.

4. What is observation?

Answer: Observation means carefully noticing something.

5. What is a scientific method?

Answer: It is a step-by-step process used to find answers to questions and solve problems.

Section F – Short Answer Questions

1. Why is curiosity important in science?

Answer: Curiosity makes us interested in the world around us. It encourages us to ask questions such as “Why?” and “How?” and motivates us to find answers.

2. Why is science compared to a jigsaw puzzle?

Answer: Science is compared to a jigsaw puzzle because every discovery adds a new piece of knowledge. There is no limit to what we can discover, and new discoveries can lead to new questions.    

3. Explain the scientific method in simple words.

Answer: First, we observe something. Then we ask a question and make a possible guess. We test the guess through experiments or observations and finally analyse the results.

4. How can science be useful in everyday life?

Answer: Science helps us solve everyday problems. For example, we may find why a pen has stopped writing, why a bicycle tyre is flat or why an electric bulb is not working.

5. Why should students observe their surroundings carefully?

Answer: Careful observation helps students notice interesting things, ask questions and discover how things work.

6. Why can a person repairing a bicycle be called a scientific thinker?

Answer: The person observes the problem, asks why the tyre is flat, searches for the cause and tests possible explanations. This follows the basic scientific method.

7. Why do new discoveries lead to more questions?

Answer: New discoveries increase our knowledge and often reveal things that we do not yet understand. Therefore, they create new questions for further investigation.

Section G – Long Answer Questions 

1. Explain the steps of the scientific method with the example of a pen that has stopped writing.

Answer:- The scientific method is a step-by-step way of finding answers.

1. Observation: We notice that the pen has stopped writing.

2. Question: We ask, “Why has the pen stopped writing?”

3. Guess: We think that the ink may have finished.

4. Testing: We open the pen and check the refill.

5. Analysis: If the refill is empty, our guess is correct. If it is not empty, we make another guess and test it.

Thus, finding the reason why a pen stopped writing is an example of the scientific method.     

2. Explain why science is important in our daily life.

Answer:- Science is present in almost every part of our daily life. It helps us understand food, water, materials, plants, animals, weather and many other things. We use scientific thinking to solve common problems. A cook, bicycle repairer or electrician may all use observation, questions and testing to solve problems. Therefore, science helps us understand our surroundings and find solutions to problems.

3. How does curiosity help us learn science?

Answer:- Curiosity makes us interested in things around us. When we are curious, we ask questions such as “Why?” and “How?”. We then observe, investigate and try to find answers. Curiosity encourages us to explore things that we do not understand. Therefore, it is an important quality for learning science.     

4. Explain the role of observation and questioning in science.

Answer:- Observation is the first important step in scientific learning. We carefully notice something interesting or unusual. This observation makes us think and ask questions. We then make a possible answer and test it. Thus, observation helps us notice problems, while questioning helps us begin the process of finding answers.

5. Why is science called a journey of exploration?

Answer:- Science is called a journey of exploration because there is always something new to discover. We can study things on Earth as well as the Sun, Moon and stars. Every discovery gives us new knowledge but can also create new questions. Scientists work together to explore these questions. Therefore, science is a continuous and enjoyable journey of discovery.
