The solved questions from inside the chapter are given below:

Question 1: What is Science?

Answer: Science is all about using our minds to think deeply, observe everything around us, and perform different experiments. By doing these things, we try to understand how our world works and solve the mysteries that exist in the universe. It helps us make sense of everything we see, hear, and experience in our daily lives.

Question 2: What will we explore with the help of this book?

Answer: With this book, we will get the chance to discover and learn about many amazing things that happen in the world around us. It will help us observe different natural events, understand how things work, and answer the questions we often wonder about. This journey through the book will make us more aware of the wonders of nature and science.

Question 3: How can we try to find answers to our questions on our own?

Answer: We can try to answer our own questions by following the process of scientific inquiry. This means we should observe things closely, ask questions, and then test our ideas by doing simple experiments. By being curious and trying things out ourselves, we can learn a lot and find explanations for things we don’t understand.

Question 4: After all, to be a wise person, you must be a “whys” person!

Answer: If we want to become wise, it’s important to always be curious and ask questions, especially “why” something happens. Being a “whys” person means we don’t just accept things as they are—we try to understand the reasons behind them. This habit of questioning helps us develop a sharp and thoughtful mind, which is a sign of true wisdom1.

Approach to Solve NCERT Solutions for Class 6 Science Chapter 1 The Wonderful World of Science

Start by learning that science is a method of investigating and comprehending the world by observing, asking, and experimenting, as emphasised in the chapter introduction.

  • Emphasise the position of curiosity and the need to ask questions regarding daily phenomena, as this propels scientific inquiry and learning.
  • Gently read each question, highlight important terms, and apply a step-by-step response following the scientific process: observe, ask, hypothesise, experiment, and conclude.
  • Use examples from everyday life and simple activities to explain concepts such as observation, the water cycle, or how materials behave, and your answers will become relatable and clear.
  • Practice stating your answers using correct scientific language and logical reasoning, just like in the NCERT Solutions, to build strong foundational skills that come in handy during future science learning and exams.

Important Question from Class 6 Science Chapter 1

The chapter "The Wonderful World of Science," introduces students to the basics of science, focusing on curiosity, observation, and the scientific method. It encourages young learners to ask questions, explore their surroundings, and understand how science helps explain everyday phenomena.

Question 1: Which of the following best describes the scientific method?

a) Memorising facts without questioning
b) Observing, asking questions, making guesses, and testing them
c) Only reading about famous scientists
d) Ignoring things we do not understand

Answer: b) Observing, asking questions, making guesses, and testing them

Explanation:
The scientific method is a systematic process used to explore and understand the world. It involves making careful observations, asking questions about what is seen, forming hypotheses (guesses), conducting experiments to test these ideas, and analysing the results. This approach helps scientists—and anyone curious—find reliable answers and solve problems, making it the foundation of scientific discovery.
