What Science Is

It starts small

A single grain of sand, a blade of grass — science can begin anywhere, at any size.

It needs curiosity

The one quality every scientist needs most is curiosity — the drive to ask why.

It never stops

From a mountain to the whole universe, there's always something new to wonder about.

Key idea
Discoveries can come from the most unexpected places.
Science connects everything — from living things right here on Earth to the stars far overhead.
Key idea
You don't need a laboratory to think like a scientist.
Your pen suddenly stops writing. You guess a reason — maybe the ink is finished — and test your guess by checking the refill. If the guess is wrong, you try again with a new one.

Anyone Can Work Like a Scientist

The cook

Wonders why the dal spilled over, and figures out the right flame and lid.

The mechanic

Guesses what's wrong with a flat tyre, and tests each guess in turn.

The electrician

Checks a faulty bulb step by step until the real fault is found.

Key idea
Science is like a giant, unending jigsaw puzzle.
Scientists across the world often work together in large teams. Not every question gets answered right away — every new discovery adds a piece, and sometimes old pieces move as our understanding improves.
