✦An original story about a question worth testing
The Child Who Asked Why
Tiny drops appear outside Ria’s cool water cup. With her father, she compares two cups and discovers how one question can lead to another.
A story to read together
The Child Who Asked Why
Take your time. Let the story unfold.
Ria liked the word why. She asked why shadows moved, why some leaves smelled strong, and why socks never seemed to stay in pairs. One humid afternoon, she set a cool cup of water on the courtyard table. A few minutes later, tiny drops covered its outside. “Why is my cup wet?” she asked. Her father put down his newspaper. “What do you think might explain it?”
Two possible answers
Ria thought the cup might have a tiny hole. Then she wondered whether someone had splashed it. Her father listened to both ideas. Together they dried the outside and set the cup on a clean tray where nobody would touch it. They watched the drops return. The tray had caught no splash from above. “It could still be a hole,” Ria said. “We need another way to check.” Her father brought a second cup of the same kind, and Ria reached for her notebook.
A careful comparison
They put the same amount of water in each cup. One held cool water; the other held water at room temperature. They dried both outsides and placed them beside each other in the shade. After a while, many drops appeared on the cool cup, while the other stayed mostly dry. Ria drew the cups with different numbers of dots. Their little comparison did not answer every question, but it showed that the cool surface mattered. A cup could get wet outside even when its water was not leaking.
Water already in the air
Her father explained that the surrounding air contained water vapour they could not see. Near the cool cup, some water vapour cooled enough to become liquid drops on the outside. That change was called condensation. Ria touched the tray with one finger and looked at her drawing. “So the drops can come from the air?” she asked. Her father nodded. “Under these conditions, yes.” They noticed that the drops grew and sometimes joined together before sliding down the cup.
A notebook with space
Ria wrote her first guess beside her new explanation. She did not cross the guess out so hard that nobody could read it. It showed how her thinking had changed. At dinner, she told Grandma about the two cups and the invisible water vapour. Then she asked whether the same thing happened on a bathroom mirror. Grandma smiled. “That sounds like a question for another day.” Ria turned to a fresh page. She had found one useful answer, and her notebook still had room for more.

After the final page
There is no single right answer. Invite young readers to notice, wonder and imagine.
What were Ria’s first two ideas?
Why did they use two similar cups with different water temperatures?
What did Ria learn from keeping her first guess in the notebook?
Make something: With an adult, draw observations of two unbreakable cups, one with cool water and one with room-temperature water. Record what happens without expecting a fixed result.
