Once upon a time, there was a little water droplet named Drop. Drop lived happily in a sunny puddle.

One warm morning, the sun shined brightly. Drop felt the warmth and began a new adventure

The sun warmed the water, and Drop changed into invisible water vapor. Up into the air, Drop went!

Drop floated higher and higher. The air was cooler up in the sky.

The water vapor cooled and turned into tiny liquid water droplets. Together, they formed a cloud.

More tiny droplets joined Drop's cloud. The droplets bumped together and grew bigger.

The droplets became heavy, and water fell from the cloud as rain. Drop was on the move again!

Splash! Drop landed on a little garden. The flowers and grass drank up some of the rain.
