Pola was a mole who spent her days underground, so she trusted things she couldn't see. That made her perfect for magnets — because a magnet's pull works across a gap, with nothing touching at all.
"You can't see the force," Pola liked to say, "but you can feel it, and you can predict it."
Pola held a magnet near an iron nail and stopped, a whisker's-width away. "Predict — will the nail jump to the magnet without me touching it?" A lab-mate guessed no. But tick — the nail leaped across the tiny gap.
"Magnetism acts at a distance," Pola said. "No contact needed. The pull IS the force."
Then Pola tried the magnet on a copper coin, a plastic block, and a gold ring. Nothing moved. "But those are metal!" a friend protested. Pola smiled. "Only iron, cobalt, and nickel are magnetic — not ALL metals, and not just anything shiny."
The friend's guess had been a good, common one. It just needed testing.
Pola brought out two magnets. "North to south — predict." Snap — they pulled together. "North to north — predict." Push — they shoved apart before touching. A lab-mate had guessed they'd stick either way, and watched, wide-eyed, as like poles repelled.
"A wrong prediction shows you exactly what to look for," Pola said kindly.
At day's end Pola tidied her magnets, pleased. The forces were invisible, but she'd predicted every one and watched the world agree.
"You understand the pull nobody can see," said the lab-mate.
Pola's small eyes shone. Trusting an invisible force had once felt strange — how do you believe in something you can't watch? But predicting it and feeling it answer, again and again, made the invisible feel as real as anything. Understanding the unseen was its own quiet thrill.

Read the drama script
- Narrator: From Spark and Anvil and Sciquest — this is Pola, in chapter 1 of the Sciquest cast.
- Narrator: This drama uses an AI-generated voice. Voiced via Gemini 2.5.
- Narrator: Pola is a bright little vole who carries a small magnet everywhere she goes.
- Pola: A magnet can pull on some things without even touching them! A push or a pull, right across a little gap. Isn't that strange and wonderful?
- Narrator: Pola set a paperclip on the table and held the magnet a little away.
- Pola: Predict — I won't touch the clip. As I move the magnet closer, what will the clip do?
- Narrator: A young shrew guessed.
- Shrew: Nothing? You're not touching it.
- Pola: Observe! Closer... closer... and — the clip jumps to the magnet! Across the gap, no touching.
- Shrew: It moved by itself!
- Pola: Not by itself — the magnet PULLED it, without touching. That's magnetism: a pull that reaches across a space.
- Narrator: The shrew tested the magnet on everything — clips yes, pebbles no.
- Pola: A magnet pulls some things across a gap, no touch needed. Predict, observe, explain. That's what makes Pola, Pola.

Reading together with a grown-up? A card for the grown-up
For the grown-up: ask one question, then wait. When they answer, add one word to what they said. Tap the button when they have said something — that is one turn each, a circle. Nothing is recorded or kept.
Let them finish it
Say “Pola pulls without ever touching — magnetism reaches across …” and stop. Let them finish it.
Now wait. Count slowly to five in your head. Their answer is worth the quiet.

The SciQuest ensemble
Pola is one of the friends in SciQuest. Each friend shows you one idea by how they act; meet them all and you have the whole subject.
-
Zoomi
Forces & motion — a roadrunner who speeds up only when one push wins; unequal force IS the change in motion
-
Loopa
Life cycles — a frog who grows egg → tadpole → frog and begins again; the loop IS the life cycle
-
Genna
Inherited traits + variation — a moth who passes on wing-color, and the shade that hides survives; variation IS the survival trait
