This is Ken. He has been alive for over 4 billion years. He continues his journey through the water cycle. Right now, he is falling into a lake as a rain droplet/ precipitation. The lake is Ken's favorite place.
After several days, Ken sinks into the ground, becoming groundwater. Ken does not like it here because it is boring and he can only get out through a plant, well, or river discharge.
Ken is relieved because he leaves the groundwater. He filters into a river as discharge. Ken likes it here more until..........
PHEW! THE SUN IS COOKING! I'M GOING TO EVOPRATE! HELP ME!!!!!!! I'M FLOATING AWAY!!!!
It's cooling down up here! I'm going to condense into a water droplet because of the lower temperatures!
Eventually, there are too many water droplets joining Ken. Ken falls back into a lake as precipitation.
