Rain & Puddles
Know that rain falls from clouds, puddle water can evaporate into the air as water vapor, and water can form cloud drops and fall again as rain in the water cycle.
What a learner can do afterwards
- State that rain falls from clouds
- Explain how evaporation moves puddle water into the air as water vapor
- Describe how water can enter the air, form cloud drops and fall as rain in a repeating process

Rain falls from clouds. Clouds contain tiny water drops. Drops can join and grow. When they grow big enough, they fall as rain.
Puddle water can change into water vapor, an invisible form of water in the air. This change is called evaporation. The puddle gets smaller as water leaves it. Sunshine can warm the water. With other things the same, warmer water usually evaporates faster. Water can evaporate on cloudy days too.
Puddle water can evaporate into the air as water vapor. The vapor can cool and form tiny cloud drops. These drops can grow and fall as rain. This repeating movement is part of the water cycle.
Mia's metal tray has no holes. Later, it holds less water. None spilled or was taken out. Water cannot soak through metal. Some evaporated into the air as water vapor. Water can also soak into soil beneath a puddle.

Two places water can go
Imagine water in a metal tray and a puddle on soil. It is a warm day. No water spills or is taken away.
The tray has no holes. Its water cannot soak through the metal. It can evaporate into the air as invisible water vapor.
The puddle's water can evaporate too. Some may also soak into the soil. Both places may look drier later, but the water can take different paths. Before explaining a shrinking puddle, look at where it is. Could water soak in? Could it evaporate?
