1.1 Happy Exploring!
Even the Earth and the Moon can cast shadows, leading to the fascinating phenomena of eclipses. And of course, we have day and night because the Earth rotates on its axis. Understanding all of this requires knowing how the Earth rotates, how the Moon goes around the Earth, and the Earth around the Sun — and the consequences of these movements on our beautiful planet.
While all this might make your head spin, think about it — isn't it amazing that we humans can wonder about the wonderful world we live in?
In the chapters that follow, you will also make simple observations and do fun experiments, and dive into topics that need careful thinking. Each chapter builds on what you already know and encourages you to ask questions, explore, do hands-on experiments, and think like a scientist!
🔬 Your approach this year: As you will find out, even those experiments that seem to confirm what we think will happen, might lead to some additional questions that might need more experiments and more questions. That is the beauty of science — every answer leads to new questions!
Activity 1.1: Question the Answer
In school or during tests, you are usually given questions and expected to find the answers. But let us turn that around! Great scientists don't just answer questions — they ask amazing ones! Remember what we learned in Grade 6: "To be a wise person, you must be a 'whys' person."
📖 The Challenge: Look at the answers given below. Your task is to come up with a curious, creative, and fun question or situation that could lead to these answers. There are never any wrong questions — so let your imagination run wild!

The funnier and more creative, the better!
• "What would you say if you fell into a swimming pool fully clothed?"
• "What did the space traveller say when his spaceship started leaking?"
• "How would you react if it suddenly started pouring rain during a picnic?"
The funnier and more creative, the better!
Answer: "42"
Hint: This could be the answer to many questions — mathematical, silly, or philosophical!
Possible questions:
• "What is 6 × 7?"
• "How many teeth does an adult human have? (approximately — it's actually 32, but creative license!)"
• "What is 32 + 10?"
• "How do we ensure getting equal shares of cake?" → "Cut it into 42 pieces!"
The point is: ask a more interesting and not obvious question. "What is 32+10?" is straightforward. "What is the answer to life, the universe, and everything?" (from a famous science fiction book) is much more interesting!
• "What is 6 × 7?"
• "How many teeth does an adult human have? (approximately — it's actually 32, but creative license!)"
• "What is 32 + 10?"
• "How do we ensure getting equal shares of cake?" → "Cut it into 42 pieces!"
The point is: ask a more interesting and not obvious question. "What is 32+10?" is straightforward. "What is the answer to life, the universe, and everything?" (from a famous science fiction book) is much more interesting!
💡 The Key Lesson: It is equally important to ask interesting questions — great scientists don't just answer questions, they ask amazing ones! A question like "What is 32+10?" is very different from "How do we ensure equal shares of cake?" Both lead to the number 42, but the second question is far more interesting and useful. Science thrives on creative, thoughtful questioning.

📋 Competency-Based Questions
A teacher gives the class an answer: "Because it was raining." She asks the students to come up with different questions that could lead to this answer. Ravi says "Why did you carry an umbrella?" Priya says "Why are the roads wet?" and Arun says "Why did the cricket match get cancelled?"
Q1. L2 Understand What skill is the teacher trying to develop in her students through this activity?
Answer: B. The teacher is developing creative questioning skills — the ability to think of multiple possible scenarios that lead to the same outcome. This is a key part of scientific thinking, where we consider different hypotheses for the same observation.
Q2. L1 Remember Fill in the blank: Every answer in science leads to new __________.
Answer: questions
Q3. L4 Analyse Why is asking "How do we ensure getting equal shares of cake?" a better question than asking "What is 32 + 10?" even though both can lead to the number 42? (Short Answer — 2 marks)
Answer: "What is 32+10?" is a straightforward arithmetic problem with one obvious approach. "How do we ensure equal shares of cake?" is a more interesting question because it connects mathematics to a real-life situation, requires thinking about fairness and practical methods, and can be answered in multiple creative ways. Good science questions connect concepts to real-world problems and encourage deeper thinking.
Q4. L5 Evaluate "Some experiments that seem to confirm what we already think might lead to new questions." Why is this important in science? (3 marks)
Answer: This is important because science is never "finished." Even when an experiment confirms our hypothesis, the results might reveal unexpected details or patterns that raise new questions. For example, confirming that plants need sunlight to grow might lead to asking "How much sunlight is enough?" or "Can plants grow under artificial light?" These follow-up questions drive scientific progress. If scientists stopped after confirming their first hypothesis, many important discoveries would never have been made.
Q5. L6 Create HOT: The answer is "Because the ice melted." Write three different creative questions — one from physics, one from daily life, and one funny one — that could all lead to this answer. (3 marks)
Hint: Physics: Think about heat transfer, temperature, state changes. Daily life: Think about drinks, food, weather. Funny: Think of silly scenarios involving ice — slipping, sculptures, ice cream disasters.
🔗 Assertion–Reason Questions
Assertion (A): Asking creative questions is an important part of being a scientist.
Reason (R): Scientists make discoveries by questioning observations and not just accepting them without thought.
Answer: A. Both are true. Creative questioning is essential for scientific discovery (Assertion), and the Reason correctly explains why — scientists progress by questioning what they observe rather than passively accepting it.
Assertion (A): Physics, chemistry, and biology are completely separate subjects with no connection to each other.
Reason (R): Scientific ideas in one area often inspire discoveries in another.
Answer: D. The Assertion is false — physics, chemistry, and biology are deeply interconnected (e.g., photosynthesis involves biology, chemistry, and physics of light). The Reason is true — scientific ideas across branches do inspire each other.
