1Activity 1.1: Let us think and write2 questions
Q.1Write about a similar problem that you tried to solve.v
Solution

This is similar to the pen example in the chapter because it begins with observing a problem and asking why it happened.

Answer:

One example is a torch that did not glow. The problem could be described as: “The torch was switched on, but no light came out.”

Q.2What steps did you take?v
Solution

The steps follow the pattern described in the chapter: observe, ask a question, guess a possible reason, test the guess, and analyse the result.

Answer:

I observed the problem, guessed that the batteries might be weak, checked the batteries, replaced them, and tested the torch again. If it still did not work, I would check the bulb and switch.

2Activity 1.2: Let us think and write1 questions
Q.1Describe a daily life situation where you think someone was following a scientific method.v
Solution

The chapter explains that people such as bicycle repair persons or electricians work like scientists when they ask questions and test possible answers.

Answer:

A bicycle repair person finding a puncture follows a scientific method. They observe that the tyre is flat, ask where the air leaked out, test the tube in water to locate bubbles, identify the hole, repair it, and check whether the tyre holds air.

3Activity 1.3: Let us think and write2 questions
Q.1If you have to ask “Why?” about something, what would you ask about?v
Solution

The chapter encourages curiosity about surroundings and the sky, including asking why stars shine and how things in nature work.

Answer:

I would ask, “Why do stars seem to disappear during the day even though they are still in the sky?”

Q.2Try to write down how you would attempt to find an answer to your question.v
Solution

This answer follows the process of making observations, asking questions, testing or checking possible explanations, and learning with others.

Answer:

I would first write my guess, then observe the sky at night, dawn and daytime. I would compare how bright the Sun is with the stars, read a reliable book or ask my teacher, and discuss the explanation with classmates.
