Why do puddles disappear?
Puddles disappear because the sun warms the water into a gas called vapor.
Pip’s answer
- Puddles disappear because the sun warms the water into a gas called vapor.
- Tiny bits of water jiggle loose and float up into the air.
- Bit by bit, the puddle gets smaller and smaller.
- Ooh, that floating water can help make new clouds in the sky!
For grown-ups
Puddles shrink through evaporation: water molecules at the surface gain enough energy from the sun's warmth and moving air to escape as invisible water vapor. Warm, sunny, windy days make puddles disappear fastest. Some water also soaks into the ground.
Ask your child: Shall we draw chalk around a puddle and check how it shrinks?
