Story text
Curious fox Fox and his squirrel friend are playing a shadow-stepping game when they discover their afternoon shadows are much longer than at noon. Using his toolkit, Fox launches an exploration. Through a simulation experiment, he understands the relationship between Earth's rotation and the sun's position, and together with his friends, they invent a fun shadow theater.

In Sunshine Forest, there lived a little fox named Fox. He had a deep blue all-purpose toolkit that he never went anywhere without. It contained a flashlight, a tape measure, a magnifying glass, and all sorts of strange and adorable little gadgets. Fox was endlessly curious about everything in the world. One sunny noon, his good friend, a squirrel named Skip who wore a little leaf vest, 'swished' down from a tree and landed right in front of him.
"Fox, stop fiddling with that pinecone! The sun is so nice, let's play step-on-the-shadow!" Skip hopped in place, the round shadow under his feet bouncing along.
"Okay!" Fox immediately put the pinecone in his pocket, his eyes crinkling into crescent moons. "Let's see who steps on the other's shadow first!"

The game began! The two little friends chased each other across the grassy clearing.
"Watch my nimble steps!" Skip jumped left and right, trying to get behind Fox.
"My shadow is clever!" Fox spun around quickly, his red tail sweeping the ground, his shadow dodging nimbly.
The noon sun shone straight down on them from overhead, making their shadows short and dark, like little black pads stuck right to their feet. Fox almost stepped on Skip's shadow several times, but because the shadow was so short, he always missed by just a little. They played until they were panting and red-faced, finally bursting into laughter together and deciding to go drink some dewdrop water under the big oak tree nearby.

It was nice and cool in the shade. They chatted, and before they knew it, the sun had quietly moved quite a bit toward the western hills. Rested, Skip leaped up. "Another round!"
The two ran back to the center of the clearing. Fox had just gotten into position when he let out a surprised "Huh?" and froze. He looked down at the ground, his eyes wide.
"Skip, look at our shadows! They... have they 'grown'?"
Skip looked down and gasped too. "Wow! Really! My shadow got so—long!" The little round pad from before had now stretched into a long, thin, wiggling gray ribbon, extending from his feet all the way out, almost touching the distant flower bushes!

"That's not fair!" Skip tried to jump and step on Fox's shadow, but the shadow was now like a soft, long red snake. With Fox's slight movements, the shadow's head swayed far away, completely out of reach. "The shadows got longer, the game got harder!"
But Fox didn't respond right away. He was completely captivated by this new discovery. He stroked his furry chin, amber eyes sparkling with thought. "Strange, very strange. Why would our shadows change so much in such a short time, when we're the same? Do shadows 'grow' by themselves? Or is there another reason?"
He immediately opened his all-purpose toolkit, pulled out his notebook and a short pencil, and began earnestly drawing a comparison of the short and long shadows. A brand new exploration was about to begin!
