The same water on Earth keeps going round and round — for millions of years!
The water you drink today might once have been a raindrop in a cloud, a river in the jungle, or even a puddle a dinosaur splashed in! 🦕
Water never disappears — it just changes its shape and travels in a big circle called the water cycle. Let's follow a single water droplet on its journey. Tap Next to begin!
The sun warms up the sea, rivers and puddles. The water gets so warm it turns into an invisible gas called water vapour and floats up into the sky.
Try tapping the sun a few times and watch the water float up as vapour!
High in the sky the air is cold. The water vapour cools down and turns back into tiny water droplets. Millions of these droplets crowd together to make a cloud.
Add cold droplets together until the cloud is full!
When a cloud holds too many droplets, it becomes heavy. The droplets join up and fall down as rain (or snow and hail in cold places). In Singapore we get lots of rain! ⛈️
The rain lands and the water collects together again. It flows into rivers, lakes, reservoirs and the sea — ready for the sun to warm it up and start the whole journey again!
Tap each place below to find out where the water goes.
Now put the four steps in the right order. Drag each step into the correct numbered box.
Water vapour rising up from a warm puddle on a sunny day — which step of the water cycle is that?
Hint: think about water turning into invisible gas when it gets warm.
The water cycle never stops — it just keeps going round and round, sharing the same water with the whole world. 🌍
Great work today. Next time it rains in Singapore, you'll know exactly where that water came from! 🌧️💙
