What is Science?
As human beings, we have always been curious about our surroundings. From our earliest years, we start exploring the world — asking questions, touching things, and trying to figure out how everything works. Now, as you enter the Middle Stage of school, a brand-new subject awaits you: 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 quality for learning science is curiosity — which is why this textbook is named Curiosity. Whether you are 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.
Have you ever looked up at the night sky and wondered why the stars shine? Or watched a flower bloom and wondered how it knows when to open? These are just a few of the many mysteries that science helps us unravel.
💡 Remember: Science is like a giant, never-ending jigsaw puzzle. Every new discovery adds another piece. And the best part? There is no limit to what we can discover!
Science is Everywhere
The most wonderful thing about science is that it 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 come from unexpected places.

💧 The Water Cycle — An Example of Science in Action L4 Analyse
Have you noticed that water freezes and becomes ice when we cool it, and boils to become steam when we heat it? Water continuously moves through a cycle on Earth. Click on each stage to learn more:
☀️ Evaporation: The Sun heats up water in rivers, lakes, and oceans. The water turns into water vapour (gas) and rises into the air. This is why puddles disappear on a sunny day!
☁️ Condensation: As water vapour rises, it cools down and changes back into tiny water droplets. These droplets come together to form clouds. This is like the water drops you see on a cold glass of water!
🌧️ Precipitation: When clouds become heavy with water droplets, the water falls back to Earth as rain, snow, or hail. This is called precipitation.
🌊 Collection: The rain water flows into rivers, lakes, and oceans, or seeps into the ground. The cycle then begins again with evaporation!
🧪 Think & Explore — Science Around You
L2 Understand
🤔 Think first: Before reading further, can you name three things around you right now that involve science? Write them down!
Try this:
- Look around your room or classroom. Pick any 5 objects.
- For each object, write down one science question about it (e.g., "Why is glass transparent?").
- Discuss your questions with a friend. Can you guess any answers?
What you might find: Every single object around you involves science! A plastic pen is made from petroleum chemicals. A wooden desk comes from a tree that used sunlight to grow. The bulb above you converts electrical energy into light. Even the air you breathe is a mixture of gases. Science truly is everywhere!
📋 Competency-Based Questions
Riya and her younger brother Aarav are walking through a park after rain. Riya notices that the puddles on the path are slowly getting smaller even though no one is draining them. Aarav sees a rainbow in the sky and asks, "Where do rainbows come from?" They also observe earthworms coming out of the soil.
Q1. L3 Apply Why are the puddles getting smaller on a sunny day after rain?
Answer: B. The Sun's heat causes the water in puddles to evaporate — turning liquid water into water vapour that rises into the air. This is part of the water cycle.
Q2. L1 Remember Fill in the blank: Science is a way of _________, observing, and doing things to understand the world around us.
Answer: thinking
Q3. L4 Analyse Why do you think earthworms come out of the soil after rain? (Short Answer — 2 marks)
Answer: When it rains, water fills up the tiny air spaces in the soil. Earthworms breathe through their moist skin and need air (oxygen) to survive. When the soil becomes waterlogged, they come to the surface to get enough air to breathe.
Q4. L5 Evaluate True or False: "Science can only be studied in a laboratory." Justify your answer. (3 marks)
Answer: False. Science is everywhere — in the kitchen (cooking involves chemical changes), in the park (observing plants and animals), in the sky (weather patterns and stars), and even in our own body (digestion, breathing). While laboratories provide controlled environments for experiments, science is fundamentally about observing and questioning the world around us in any setting.
Q5. L6 Create HOT: Imagine you are exploring a completely new planet. List 5 science questions you would want to investigate first and explain why each is important. (3 marks)
Hint: Think about what you would need to survive — air, water, food, shelter, temperature. What questions about the planet's atmosphere, water sources, living organisms, temperature, and materials would be most critical to answer first?
🔗 Assertion–Reason Questions
Assertion (A): Science helps us understand the world around us.
Reason (R): Science involves observing, questioning, and testing ideas systematically.
Answer: A. Science helps us understand the world (Assertion is true) precisely because it follows a systematic approach of observation, questioning, and testing (Reason is true and explains the Assertion).
Assertion (A): Curiosity is not important for learning science.
Reason (R): Scientists make discoveries by asking questions and exploring.
Answer: D. Assertion is false — curiosity is the most important quality for learning science (the textbook is named "Curiosity" for this reason). Reason is true — scientists do make discoveries by asking questions and exploring, which requires curiosity.
Assertion (A): Water on Earth continuously moves through a cycle of evaporation, condensation, and precipitation.
Reason (R): The Sun provides the energy needed to evaporate water from oceans, rivers, and lakes.
Answer: A. Both statements are true. The water cycle (evaporation → condensation → precipitation) is driven by the Sun's heat energy, which causes water to evaporate and start the cycle. So the Reason correctly explains the Assertion.
