Chapter 1. The Wonderful World of Science

NCERT Textbook Exercise

Note: This introductory chapter does not contain a separate end-of-chapter exercise. Instead, NCERT includes three "Let us think and write" activities to encourage observation, curiosity, and scientific thinking. All the textbook activities are answered below.

Activity 1.1 – Let us think and write

Question 1. Write about a similar problem that you tried to solve.

Answer:
One day, my torch suddenly stopped working. I wanted to know why it was not lighting up. First, I checked whether the switch was working properly. Then I opened the torch and examined the batteries. I found that the batteries had become weak. After replacing them with new batteries, the torch started working again.

Question 2. What steps did you take?

Answer:

• I observed that the torch was not working.
• I asked myself why it had stopped working.
• I guessed that the batteries might be weak.
• I checked the batteries to test my idea.
• I replaced the old batteries with new ones.
• I observed that the torch started working, proving my guess was correct.

Activity 1.2 – Let us think and write

Question. Describe a daily life situation where you think someone was following a scientific method.

Answer:
A bicycle mechanic repairing a punctured tyre follows the scientific method. First, the mechanic observes that the tyre has lost air. Then, he guesses that there may be a hole in the tube. He fills the tube with air and dips it in water to locate the leaking spot. After identifying the puncture, he repairs it and checks whether the tyre holds air properly. This is an example of observation, hypothesis, testing, and conclusion.

Activity 1.3 – Let us think and write

Question 1. If you have to ask "Why?" about something, what would you ask about?

Answer:
I would ask, "Why does a rainbow appear after rainfall?" because I am curious to know how sunlight and water droplets together produce different colours in the sky.

Question 2. Try to write down how you would attempt to find an answer to your question.

Answer:

• I would carefully observe when and where a rainbow appears.
• I would read my Science textbook and other reliable sources.
• I would discuss the topic with my teacher.
• I would watch a simple demonstration showing how light passes through a prism.
• I would compare my observations with the scientific explanation and draw a conclusion.
