Passage 1:
What is Science?
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. Think of it as a big adventure—we ask questions, explore the world, and try to understand how things work.
The most important thing is to have ‘Curiosity’. Whether it is studying tiny grains of sand or massive mountains, a leaf of grass, or a vast forest, there is always something new and exciting to discover.
📌 Case Study-Based Questions
- What is science according to the passage?
(Answer: Science is a way of thinking, observing, and doing things to understand the world.) - Why is curiosity important in science?
(Answer: Curiosity helps us ask questions and explore new things.) - Give two examples of things we can explore using science.
(Answer: Studying grains of sand, observing how plants grow.) - How does science help us in daily life?
(Answer: Science helps us understand how things work and solve problems.) - What do scientists do to uncover the secrets of the universe?
(Answer: They ask questions, observe, and conduct experiments.)
📖 Passage 2:
The Scientific Method
Science is not just about memorizing facts and figures or doing experiments. It is about following a step-by-step process that helps us find answers to our questions.
First, we observe something that we find interesting or do not understand. Then, we guess a possible answer to that question. We test this guess through experiments or more observations. Finally, we analyze the results to see if it actually answered our question.
📌 Case Study-Based Questions
- What is the first step in the scientific method?
(Answer: Observing something that we find interesting or do not understand.) - What do scientists do after making a guess about something?
(Answer: They test their guess through experiments or more observations.) - Why is it important to analyze the results in the scientific method?
(Answer: To check if the answer is correct and to improve understanding.) - Can science work without experiments? Why or why not?
(Answer: No, because experiments help confirm whether our guesses are right or wrong.) - How do scientists find solutions to problems?
(Answer: By following a step-by-step process: observation, hypothesis, experiment, and analysis.)
📖 Passage 3:
The Role of Science in Daily Life
Science is everywhere. From the depths of the ocean to the vastness of outer space, from what is cooking in the kitchen to what is happening on the playground, some of the most groundbreaking discoveries have often come from unexpected places.
Even in daily life, we unknowingly apply science—whether it is mixing ingredients in the kitchen, finding out why a pen stops writing, or repairing a bicycle.
📌 Case Study-Based Questions
- Where can we find science around us?
(Answer: In the ocean, space, kitchen, playground, and many other places.) - Give one example of science used in the kitchen.
(Answer: Mixing ingredients to prepare food.) - How does science help when a pen stops writing?
(Answer: We check if the ink is finished or dried up, which is a scientific process.) - What is the main idea of the passage?
(Answer: Science is present in everything we do, even in daily life activities.) - What is one surprising fact about scientific discoveries?
(Answer: Some of the most important discoveries come from unexpected places.)
