The Day the Playground Melted

When the school playground looks like it’s slowly melting, the Junior Cadets race to find out what’s really happening and what solids, liquids, and gases have to do with it.

SCIENCE FLASHCARD

Concept

Matter exists mainly as solids, liquids, and gases. Each behaves differently.

How it works

Heat makes solids melt into liquids; more heat makes liquids evaporate into gases.

Example

Ice cubes melting, water boiling, steam rising from a kettle.
If something looks like it’s “melting,” check if heat or sunlight is doing something surprising.

Scene 1 – The Melting Playground

[ILLUSTRATION: A school playground shimmering with heat waves, the slide looking soft and wobbly]

Leo ran into Dr. Zaptain’s lab so fast he nearly slipped. His face was red and sweaty.

Leo: “Professor! The playground is melting!”

Mia rushed in right behind him, out of breath.

Mia: “No joke! The slide looks soft, and the hopscotch lines are all… wiggly!”

Dr. Zaptain blinked twice, then three times, adjusting his bow tie.

Dr. Zaptain: “Melting? Fascinating! Either it’s a scientific mystery… or someone spilled a giant pot of soup.”

He grabbed his lab coat dramatically.

Dr. Zaptain: “Cadets, onward! To the playground!”

When they arrived, heat waves shimmered above the ground. The bright yellow slide looked slightly bent, as if it were tired of being a slide.

Mia: “It really does look like it’s melting.”

Leo poked the slide cautiously.

Leo: “It’s warm… and squishy. Slides aren’t supposed to be squishy.”

Dr. Zaptain crouched down and pressed his palm against the slide, then gasped theatrically.

Dr. Zaptain: “Aha! A classic case of misunderstood matter!”

Leo: “Is that a real thing?”

Dr. Zaptain: “Oh yes. Matter comes in different states — solids, liquids, and gases. Heat can make solids look soft, but that doesn’t mean they’re melting.”

Mia squinted at the slide.

Mia: “So it’s still solid, just… tired?”

Dr. Zaptain nodded.

Dr. Zaptain: “Exactly. A very warm, very floppy solid.”

Scene 2 – Solids, Liquids, and Trickery

[ILLUSTRATION: Dr. Zaptain holding an ice cube above a cup of warm water while Leo and Mia watch closely]

Dr. Zaptain pulled an ice cube from his pocket. It was already melting from the heat.

Leo: “Why do you have ice cubes in your pocket?”

Dr. Zaptain: “For science… and for snacks. Mostly science.”

He held up the ice cube.

Dr. Zaptain: “This is a solid. Add heat—”

He dropped it into a cup of warm water he carried in his coat.

Dr. Zaptain: “—and it becomes a liquid!”

Mia leaned closer as the ice shrank quickly.

Mia: “And if you heat the liquid… it becomes gas?”

Dr. Zaptain: “Exactly! Heat is the great transformer.”

Leo wiped sweat from his forehead.

Leo: “So the playground isn’t melting. The heat is just messing with our eyes?”

Dr. Zaptain: “Yes! Those wiggly hopscotch lines? That’s hot air rising from the ground, bending the light. A heat illusion!”

Mia pressed her hand above the asphalt.

Mia: “It feels like standing over a giant oven.”

Dr. Zaptain: “Exactly! And the slide softens because plastic becomes flexible when it’s hot — but it’s still a solid.”

Just then, a faint mist floated above the sandbox.

Leo: “Okay… but what is THAT?”

Dr. Zaptain grinned.

Dr. Zaptain: “Evaporation! Water hidden in the sand heats up and escapes into the air as gas. Science is full of disappearing acts.”

Scene 3 – The Blue Drip Mystery

[ILLUSTRATION: A blue glowing droplet bouncing off a branch while Dr. Zaptain and the Cadets look surprised]

The heat began to fade as they walked home, but something else caught their attention — a strange dripping sound coming from behind the trees.

Mia froze.

Mia: “Please tell me that’s just water.”

A bright blue droplet fell from a branch… and bounced off the ground like a rubber ball.

Leo’s jaw dropped.

Leo: “Professor… water doesn’t bounce.”

Dr. Zaptain adjusted his glasses slowly.

Dr. Zaptain: “No, it certainly does not.”

Another glowing droplet wobbled on a leaf, pulsing faintly like it had a heartbeat.

Dr. Zaptain: “Cadets… whatever that is, it’s not a solid… not a liquid… and definitely not a gas we know.”

Mia stepped closer, fascinated.

Mia: “So… what state of matter is it?”

Dr. Zaptain smiled, eyes sparkling.

Dr. Zaptain: “That… is the question for our next adventure!”
