Science · Weather & Climate · ages 5-7

Name ______________________ Date ____________

The sun warms a puddle. No new water is added. As its water evaporates, what happens to the puddle?
- It gets smaller
- It grows deeper
- It stays as big
Where does rain come from?
- Soil by the path
- Clouds in the sky
- Puddles on paths
When water evaporates, it turns into air.
Circle one: True False
Tiny water drops in a cloud join together. When they grow big enough, what can happen?
- They fall down as rain
- They become sunlight
- They stay in clouds forever
A puddle on a warm metal plate gets smaller. The plate has no holes. No water spills or is taken away. Where does the missing water go?
- Into soil beneath the plate
- It turns to nothing forever
- Into the air as water vapor
Read these word cards in order. What comes just after "Puddle"?
- Rain
- Water vapor
- Cloud drops
Two matching trays hold the same amount of water. Only the water's warmth is different. The warmer water dries faster. Why?
- Warmth helps water evaporate faster
- Warmth makes water stop being water
- Cool water never becomes water vapor
Ben says, "Once a puddle dries, that water is gone forever." Which idea would help him explain what happened?
- It turns to rock deep below the ground
- It has gone forever and cannot be rain
- It enters the air and can fall as rain

Answer key

For grown-ups. Fold this page away before handing over the rest.

It gets smaller · Evaporation moves water into the air as water vapor. Less liquid water remains in the puddle, so it gets smaller.
Clouds in the sky · Rain falls from clouds. Water drops in a cloud can join, grow and fall as rain.
False · Water vapor is still water. Evaporation changes liquid water into invisible water vapor in the air.
They fall down as rain · Cloud drops can join and grow. When they are big enough, they fall as rain.
Into the air as water vapor · Water cannot soak through the metal plate, and none spills or is removed. Some liquid water evaporates into the air as water vapor.
Water vapor · The card after "Puddle" says "Water vapor". It shows water leaving a puddle by evaporation.
Warmth helps water evaporate faster · With other things the same, warmer water usually evaporates faster. Liquid water changes into water vapor in the air.
It enters the air and can fall as rain · Puddle water can enter the air as water vapor. The vapor can form cloud drops that grow and fall as rain. The water has not stopped existing.
