The Water Cycle — A Simple Story for Kids
Think of water as a little traveler that never stops moving. The water cycle is the trip water takes around Earth. It happens over and over, like a circle.
Four easy steps
- Evaporation: The sun warms water in oceans, lakes, and puddles. Warm water turns into an invisible gas called water vapor and floats up. (Like steam from a kettle.)
- Condensation: The water vapor gets cooler up in the sky and turns into tiny drops. These drops join together to make clouds.
- Precipitation: When the cloud drops get heavy, they fall as rain, snow, sleet, or hail. That is precipitation.
- Collection: The fallen water goes into rivers, lakes, and oceans, or soaks into the ground. Then the sun can warm it again, and the trip starts over.
One more friend: Plants
Plants help too. They give off tiny bits of water from their leaves called transpiration, which also goes up into the air and helps make clouds.
Quick examples you know
- Steam from a cup of warm soup = evaporation.
- Dew on grass in the morning = condensation.
- Rain falling during playtime = precipitation.
- Puddles that the sun dries up = collection and then evaporation again.
Fun and easy experiment: Mini water cycle (with an adult)
What you need: a shallow bowl, a small cup, water, clear plastic wrap, a sunny window, and a small pebble.
- Put the small cup in the middle of the bowl.
- Pour water into the bowl around the cup (don't put water inside the small cup).
- Cover the bowl tightly with clear plastic wrap.
- Put a pebble gently on the plastic wrap over the small cup so the wrap dips a little toward the cup.
- Place the bowl in a sunny spot and watch for a few hours.
What you will see: Sun warms the water (evaporation). Water drops will form on the plastic (condensation). Drops will fall into the cup (precipitation and collection).
Safety note: Do this with an adult so nothing spills and you stay safe in the sun.
Check with three quick questions
- Where does water go when the sun warms it? (Up as vapor.)
- What do water drops make in the sky? (Clouds.)
- What happens when clouds get heavy? (Rain or snow falls.)
Great job! Now you know the water cycle: evaporation, condensation, precipitation, and collection. It's nature's never-ending water adventure!
