🔍 Short Answer Questions
- Q: What is science according to the introduction in Chapter 1?
A: Science is described as a process of curiosity, asking questions, performing experiments, and exploring the world to understand natural phenomena. - Q: How does the textbook encourage students to learn science?
A: By urging them to ask questions, do experiments, explore surroundings, and connect real-life experiences with science. - Q: What inspired early flight experiments as per the chapter?
A: Observations of bird wings and simple paper planes inspired early inventors to study flight. - Q: What is meant by ‘the ever-evolving world of science’?
A: It refers to the continuously growing and changing nature of scientific knowledge and discovery. - Q: How is the layout of the textbook described?
A: The page numbers follow the playful path of a butterfly and a paper plane, symbolizing free exploration.
🧠Conceptual Questions
- Q: Why does the textbook call science a way of thinking?
A: Because science involves curiosity, questioning, reasoning, and openness to new information—not just memorizing facts. - Q: Give an example of how one area of science connects to another.
A: Learning about light (physics) helps understand plant growth (biology) through photosynthesis. - Q: What does the chapter say about reversible and irreversible changes?
A: Some changes like melting ice are reversible, while others like ripening fruits or burning wood are irreversible. - Q: What role does heat play in physical changes?
A: Heat can cause substances to change state (like melting or evaporating) and can also speed up certain changes. - Q: How does the Sun contribute to the water cycle?
A: The Sun heats water, causing evaporation, which leads to condensation and rainfall.

✍️ Long Answer Questions
Q: Summarize how science is both discovery and responsibility as per the chapter.
A: Science helps us discover how nature works, but it also makes us aware of how human actions affect the environment. Being responsible means using scientific knowledge to build a more sustainable world.
Q: Explain how light helps us beyond just visibility, as explained in the chapter.
A: Light not only enables vision but also leads to scientific understanding of the universe. Its study helps explain shadows, time measurement, eclipses, and even the structure of the universe.
