LESSON 1
WHAT IS THE
WATER CYCLE?
1
Q 1: Label the water cycle diagram using arrows and water cycle words.
Evaporation: Occurs when the sun heats up water in lakes, rivers, streams, ponds,
and oceans and turns it into vapor or steam. The water vapor, or steam, leaves the
body of water and travels into the air.
Condensation: Water vapor in the air becomes cold and changes back into a liquid.
When this happens, clouds are formed.
Precipitation: Occurs when so much water has condensed that the air can no longer
hold it. Clouds get heavy and the water falls back to the earth in the form of rain, hail,
snow, or sleet.
Collection: When water descends back to the earth, it may fall into the lakes, rivers,
ponds, streams, or oceans. Some of it ends up on land and is then soaked into the
earth becoming part of the ground water. Some may travel over rocks and soil
towards larger bodies of water.

Plants in our environment
contain water in a liquid
form. They release water
vapor into the atmosphere.
When plants do this, it is
called
transpiration.
Transpiration is a kind of
evaporation.
Q5: Draw a picture to correct type of precipitations:
1-Rain is water which falls from clouds. If it rains you need an umbrella
and a raincoat.
2-Hail falls from clouds as hard and heavy balls –> hailstones
It often hails when it is windy and cold.
3-Snow falls from clouds as soft flakes
. Snow is also white and cold.
