This chapter introduces science as a process of investigation, where learning begins with curiosity, careful observation, and meaningful questions. It explains that science is not only about memorising facts but about understanding how knowledge is discovered. The chapter encourages students to ask “why” and “how”, observe everyday events closely, and think like young scientists. It highlights the importance of systematic investigation, where one factor is changed at a time, results are observed carefully, and conclusions are drawn logically. Through simple real-life examples, the chapter shows how scientific thinking helps us explore both small everyday phenomena and big challenges related to Earth and life.
Key Points
Science begins with curiosity and asking thoughtful questions.
Observation is the first step in understanding the world around us.
Science is an evolving subject where answers often lead to new questions.
Investigation in science involves planning, experimenting, and explaining results.
A good scientific investigation changes only one factor at a time.
Keeping records and notes helps in analysing observations accurately.
Experiments do not always need a laboratory; daily-life situations can be investigated scientifically.
Measurement helps make observations more reliable and comparable.
Scientific thinking balances careful observation with creative ideas.
Science helps us understand topics ranging from microorganisms to planet-wide issues.
Understanding science enables us to face challenges like health, technology use, and climate change.
Humans play an important role in both causing and solving environmental problems.
Science guides us to make responsible decisions for the future of Earth.
👉 👉Science is not just a subject but a way of thinking. By being curious, observing carefully, and investigating honestly, we can understand the world better and use scientific knowledge responsibly to protect life and the planet.
