Little Thunder spun the big wooden wheel in the barn. Click, click, click!

"Twelve months," said Suzy. "And four seasons."

The arrow stopped on December. "Summer!" said Spike. "Hot days, long swims in the dam and lots of shade for the herd."

Click, click! March. "Autumn," said Suzy. "The leaves on the fruit trees turn gold, and we pick the apples."

Click! June. Little Thunder shivered. "Winter! Frosty grass and warm rugs for the horses."

Click! September. "Spring!" said Spike. "Lambs, calves and wattle flowers everywhere."

"Wattle Day is the first of September," said Canberra the cow. "The gold wattle is Australia's flower."

"Up in the Top End, near Darwin, they have just two seasons," said Suzy. "The wet and the dry."

"Why do we have seasons at all?" asked Little Thunder.

Spike drew a circle in the dirt. "The Earth is tilted. As it travels around the sun, our part leans closer, then further away."

Little Thunder spun the wheel again. "Round and round the year we go!"
