Once upon a time there was a a happy droplet of water named Reggie. He lived in the ocean with tons of other water droplets. One hot sunny day the harmful rays of the sun beat down on Reggie, and he began to heat up. Suddenly he began to change into a gas and he floated up into the air. This is called evaporation.
Once Reggie got very high up in the sky he began to condense. Then he turned into a cloud, and as he looked around he say other water droplets from his home in the ocean.
Then Reggie fell from the sky. He was being pulled down to earth due to gravity, a process called precipitation. Reggie was finally a liquid again, but he was in a different ocean. The local droplets called it the Pacific or something like that. Reggie had to make all new friends, and he would never see his family again.
