D1 What is science, according to the chapter?
Science is a way of thinking, observing and doing things to understand the world we live in and to uncover the secrets of the universe. It is like a big adventure in which we ask questions, explore the world and try to understand how things work.
D2 Why is the textbook called Curiosity?
Because the most important thing needed to do science is curiosity — the urge to explore and ask questions about our surroundings. Curiosity is where the title of the book comes from.
D3 In what ways is science like a jigsaw puzzle?
Every new discovery adds a piece to the puzzle; the puzzle never ends because each new piece leads to more questions; and sometimes a piece is found to be in the wrong place and has to be moved, just as new discoveries can change our understanding of the world.
D4 Name the five steps of the scientific method in the correct order.
Observe something interesting or puzzling → ask a question about it → guess a possible answer → test the guess through experiments or more observations → analyse the results to see if they answered the question.
D5 Give two examples from the chapter of people who work like scientists in daily life.
A cook who wonders why the dal spilled out of the cooker and guesses there was too much water; a bicycle repair person who tries to find where the air leaked from a flat tyre. (An electrician checking whether the bulb or the switch is faulty is a third example.)
E · Long answers 2 × 5 = 10 marks
E1 Using the example of a pen that stops writing, explain each step of the scientific method. What should you do if your first guess turns out to be wrong?
1. Observe: I notice that my pen has stopped writing.
2. Question: This makes me ask, "Why did my pen stop writing?"
3. Guess: I guess a possible answer — the ink has finished.
4. Test: I open the pen and check the ink refill.
5. Analyse: If the refill is empty, my guess was correct and I have my answer.
If the guess is wrong — the refill still has ink — I do not give up. I make a new guess, for example that the ink has dried up, and test that guess in a different way. I keep guessing and testing until the results answer my question. This is exactly how science works.
E2 "In a way, we are all scientists." Explain this statement with examples from the chapter, and say what else is needed to learn science well.
Scientists are people who follow the scientific method to solve problems or discover new things — but the chapter says that anyone who follows the scientific method is working like a scientist. We do this every day, knowingly or unknowingly.
- A cook wonders why the dal spilled out of the cooker and guesses there was too much water.
- A bicycle repair person investigates where the air leaked from a flat tyre.
- An electrician tests whether a light bulb or the switch is the problem.
Each of them observes a problem, asks a question, guesses, tests and analyses — so in a way they are all scientists.
To learn science well, the chapter says the first and foremost thing is to be curious and to observe our surroundings keenly, asking how and why. Science is also rarely done alone — scientists work in large teams, so we should discover things together with friends. Learning science helps us use the same method to solve bigger problems and more mysteries of the universe.
F · HOTS 2 × 3 = 6 marks
Higher-order thinking. Reason it out rather than recalling a fact.
F1 Riya says, "The scientific method failed because my first guess was wrong." Is she right? Explain using the chapter.
No. A wrong guess is a normal part of the scientific method, not a failure. In the pen example, when the refill turns out not to be empty, the chapter simply says to make another guess (the ink may have dried up) and test it. The test did its job: it told Riya her first guess was wrong and saved her from believing something untrue. The method only "fails" if she stops guessing and testing.
F2 The chapter says a piece of the science jigsaw is sometimes in the wrong place and needs to be moved. Why is it a good thing, not a bad thing, that science can change its mind?
Because science is built on testing, not on simply believing. If new observations or experiments show that an old idea was wrong, moving that "piece" makes our picture of the world more accurate. A puzzle with a wrongly placed piece can never be completed correctly. So being willing to change our understanding is what lets science keep improving — every new piece leads to better questions and better answers.
