"Detectives, today we solve farm mysteries," said Suzy.

Little Thunder held up his magnifying glass. "Ready!"

First clue: a rock and a hen. "Which one is living?" asked Spike.

"The hen!" said Little Thunder. "She eats, grows and makes chicks. The rock just sits."

Next they found an egg in the coop. Crack! Out came a fluffy chick.

"Egg, chick, then hen," said Suzy. "That's a life cycle."

By the dam, they spotted jelly-like frog eggs. Tiny tadpoles wiggled nearby, and a big frog sat on a rock.

"Eggs, tadpoles, frog!" cheered Little Thunder.

Then Canberra the cow pointed at a sunflower. "Can you find the parts?"

"Roots drink water, the stem holds it up, leaves catch sunlight, and the flower makes seeds," said Spike.

Just then, dark clouds rolled in. Plip, plop! Rain fell into the dam.

"The sun will warm the water, it will rise up into the clouds, and fall again as rain," said Suzy.

Little Thunder grinned. "Case closed, detectives!"
