Question What is Science?
Science uses thinking, observation, and action to understand the world; curiosity starts the questioning.
Science is a way of thinking, observing, and doing things to understand the world. Curiosity helps us ask questions and explore how things work.
Question What will we explore?
We will investigate life, food, water, materials, motion, heat, Earth, and space.
The book explores living things, food, water, materials, magnets, motion, heat, Earth, and objects in space. It also shows how science connects with everyday life.
Question Finding answers
Observe → ask → guess → test → analyse the result. Revise the guess if needed.
We can observe, ask a question, make a possible guess, test it, and study the results. If the guess does not work, we try another one.
Question Science as a puzzle
Every discovery adds knowledge, raises new questions, and may improve an earlier explanation.
Science is like an unending puzzle because discoveries add to our knowledge, lead to new questions, and sometimes help us correct earlier ideas.
Question A “whys” person
Keep asking why, then use observations and tests to find evidence-based answers.
It means that asking “why?” helps us learn. We should be curious, look for evidence, and test our ideas.

Question Activity 1.1
Sample: Observe the torch is dark; check the switch; test fresh batteries; then check the bulb if needed.
Example: My torch stopped working. I checked the switch, guessed that the batteries were weak, and replaced them. The torch lit up, so the battery guess was correct. If it stayed dark, I would check the bulb and connections.
Question Activity 1.2
A repairer observes a flat tyre, tests for a leak, patches it, and checks whether the tyre now holds air.
A bicycle repairer can find a leak by inflating the tyre, checking for bubbles in water, patching the leaking spot, and testing the tyre again.
Question Activity 1.3
Sample: Test two equally wet cloths in sunlight and shade, then compare their drying.
Question: Why does a wet shirt dry faster in sunlight? I would wet two similar cloth pieces equally, place one in sunlight and one in shade, then compare how quickly they dry.
