Passage 1: What is Science?

Extract:

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.

 Passage 2: The Scientific Method

Extract:

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

1. What is the first step in the scientific method?
   (Answer: Observing something that we find interesting or do not understand.)
2. What do scientists do after making a guess about something?
   (Answer: They test their guess through experiments or more observations.)
3. Why is it important to analyze the results in the scientific method?
   (Answer: To check if the answer is correct and to improve understanding.)
4. Can science work without experiments? Why or why not?
   (Answer: No, because experiments help confirm whether our guesses are right or wrong.)
5. 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

Extract:

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

1. Where can we find science around us?
   (Answer: In the ocean, space, kitchen, playground, and many other places.)
2. Give one example of science used in the kitchen.
   (Answer: Mixing ingredients to prepare food.)
3. 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.)
4. What is the main idea of the passage?
   (Answer: Science is present in everything we do, even in daily life activities.)
5. What is one surprising fact about scientific discoveries?
   (Answer: Some of the most important discoveries come from unexpected places.)

Passage 4-Science as a Puzzle

Extract:

Science is like a giant and unending jigsaw puzzle. Every new discovery we make adds another piece to that puzzle. And you know the best thing about this puzzle? There is no limit to what we can discover, since every new piece of knowledge leads to more questions and more things to find out.

 Case Study-Based Questions

1. How is science similar to a puzzle?
   (Answer: Every discovery adds a new piece to our understanding, just like a puzzle.)
2. Can science ever be fully completed? Why or why not?
   (Answer: No, because there are always new questions and discoveries.)
3. What happens when a piece of the puzzle is put in the wrong place?
   (Answer: New discoveries can change our understanding and correct mistakes.)
4. Why is it exciting to learn science?
   (Answer: Because there is always something new to discover.)
5. How do scientists solve scientific puzzles?
   (Answer: By making observations, experimenting, and analyzing data.)

Passage 5- Our Home - Planet Earth

Extract:

We will start off by looking at our home, planet Earth. It is the only planet we know that supports life, and it has an environment that we must protect. There is an amazing variety of life on Earth—plants and animals that have managed to survive and thrive in different regions on this planet.

Our planet provides everything we need—water, air, food, and a suitable climate. However, humans often take these resources for granted. Deforestation, pollution, and climate change are harming our environment. If we do not take action to protect Earth, future generations may not have the same natural beauty and resources that we do today.

Earth has many fascinating features. The land is divided into mountains, deserts, forests, and plains, each with its own unique plants and animals. The oceans cover more than 70% of the planet and hold countless marine species. From the deep sea to the highest peaks, Earth is full of wonders waiting to be explored.

 Case Study-Based Questions

1. Why is Earth considered unique?
   (Answer: It is the only known planet that supports life.)
2. What are some resources that Earth provides for survival?
   (Answer: Water, air, food, and a suitable climate.)
3. How are human activities harming the environment?
   (Answer: Through deforestation, pollution, and climate change.)
4. What percentage of Earth is covered by oceans?
   (Answer: More than 70%.)
5. Name two natural features of Earth and an example of life found in each.
   (Answer: Forests—tigers; Oceans—whales.)

 Passage 6: The Importance of Water

Extract:

Along with food, we need water to survive. Water is such a delightful substance. Have you ever run and jumped in a puddle when it rained? Do you ever wonder why and how it rains?

Have you noticed that water freezes and becomes ice when we cool it and boils and becomes steam when we heat it? These changes happen because of temperature differences. Water exists in three forms—solid (ice), liquid (water), and gas (steam). This cycle of change helps in the water cycle, which is responsible for rain, rivers, and lakes.

Without water, life on Earth would not be possible. Plants need water to grow, animals need it to drink, and humans use it for daily activities like cooking, bathing, and cleaning. However, fresh water is limited, and pollution is making it even scarcer. It is important to use water wisely and avoid wastage.

 Case Study-Based Questions

1. In which three forms does water exist?
   (Answer: Solid (ice), liquid (water), and gas (steam).)
2. How does the water cycle help in forming rain?
   (Answer: Water evaporates, forms clouds, and falls back as rain.)
3. Why is water essential for plants and animals?
   (Answer: Plants need it to grow, and animals need it to drink.)
4. Why should we save water?
   (Answer: Because fresh water is limited, and pollution is making it scarcer.)
5. Give one example of how you use water daily.
   (Answer: Drinking, cooking, bathing, etc.)
