📖 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."
- Science starts with curiosity — asking questions about things around us
- The name of the Class 6 Science book is "Curiosity" — because curiosity is the most important thing in science
- Science is like a big adventure — we ask questions, explore the world and try to understand how things work
🌍 Science is Everywhere!
Science covers everything around us, for example:
| Topic | Questions Science Asks |
|---|---|
| Plants & Animals | How do they grow? How do they survive? |
| Food | What are dishes made of? Where do ingredients come from? |
| Water | Why does it rain? How does water freeze or boil? |
| Materials | What are things made of? How do we separate materials? |
| Sky & Space | Why do stars shine? What is beyond Earth? |
🧩 Science is Like a Jigsaw Puzzle
- Every new discovery adds another piece to the puzzle
- There is no limit to what we can discover
- Every new piece of knowledge leads to more questions
- Sometimes a piece is put in the wrong place and needs to be moved — meaning old ideas can change with new discoveries
- New discoveries often change our understanding of the world
🔎 The Scientific Method
The scientific method is a step-by-step process scientists use to find answers.
Steps of the Scientific Method:
📝 Example from the Book:
Situation: Your pen stops writing
- Question: Why did my pen stop writing?
- Guess 1: The ink finished → Test: Open pen and check refill → If empty, guess is correct ✅
- Guess 2: If ink is not finished → Maybe the ink dried up → Test: Try something else
- This process of guessing and testing is exactly the scientific method!
👨🔬 Who is a Scientist?
- Scientists are people who follow the scientific method to solve problems or discover new things
- But anyone who follows the scientific method is working like a scientist!
- Examples of everyday scientists:
- A cook wondering why the dal spilled out of the cooker
- A bicycle repair person finding out why a tyre is flat
- An electrician figuring out why a light bulb is not working
- When we ask questions and find answers — we are all scientists!
🌏 What Will We Explore in This Book?
The book will help us explore:
- Planet Earth — the only planet known to support life
- Plants and Animals — how they grow and survive in different regions
- Food — ingredients, diversity of food in India
- Water — its properties, states (ice, water, steam)
- Materials — things around us, what they are made of
- Sky & Space — Sun, Moon, stars and beyond
🤝 Science is a Team Effort
- Scientists across the world work together, often in large teams
- If you cannot find an answer yourself, ask your friends for help
- It is always more fun to discover things together

❓ Activity-Based Questions & Answers
Activity 1.1 — Write about a problem you solved:
Q. Give an example from daily life where you used the scientific method.
Answer: Suppose the fan in our room is not working.
- Observation: The fan is not rotating
- Question: Why is the fan not working?
- Hypothesis: Maybe there is no electricity / the switch is broken
- Test: Check the switch, check other lights in the room
- Result: If other lights work, the fan has a problem → Call an electrician This is the scientific method applied in daily life.
Activity 1.2 — Daily life scientific method:
Q. Describe a daily life situation where someone was following the scientific method.
Answer: A mother cooking food notices the rice is not boiling even after a long time.
- Observation: Rice is not cooked
- Question: Why is the rice not getting cooked?
- Hypothesis: Maybe the gas flame is too low
- Test: Increase the flame
- Result: Rice starts boiling → Hypothesis was correct ✅
Activity 1.3 — Ask "Why?":
Q. If you have to ask "Why?" about something around you, what would you ask?
Answer (Sample): Why does a mango turn yellow when it ripens? I would try to find the answer by observing raw and ripe mangoes and reading about what changes happen inside the fruit.
🌟 Important Extra Questions & Answers
Q1. What is science? Why is curiosity important in science?
Answer: Science is a way of thinking, observing and doing things to understand the world and uncover the secrets of the universe. Curiosity is important because it makes us ask questions. When we are curious, we start exploring and finding answers — that is exactly how science works. In fact, the Class 6 Science book is named "Curiosity" to highlight its importance.
Q2. How is science like a jigsaw puzzle?
Answer: Science is like a giant and unending jigsaw puzzle because every new discovery we make adds another piece to our knowledge. There is no limit to discoveries, and sometimes we even find that a piece was placed wrongly — meaning old beliefs may need to change with new discoveries.
Q3. What are the steps of the scientific method?
Answer: The steps are:
- Observe something interesting
- Ask a question about it
- Make a hypothesis (guess a possible answer)
- Test the hypothesis through experiments
- Analyse the results to see if the question is answered
Q4. Is only a trained scientist able to use the scientific method? Explain.
Answer: No. Anyone who follows the scientific method is working like a scientist. A cook, a bicycle repair person, an electrician — all of them observe problems, ask questions, make guesses and test them. So in a way, we are all scientists in our daily lives.
Q5. Why is Earth special compared to other planets?
Answer: Earth is the only planet we know that supports life. It has an environment with air, water and suitable temperature that allows plants, animals and human beings to survive and thrive. That is why it is important that we protect our environment.
