3
In this activity you will

• Recognize the basic parts of the water cycle
• Write a paragraph about the water cycle and draw
  a picture of what happens.

4
Evaporation

• Evaporation is the changing of a liquid into a
  gas. You must have heat in order for a liquid to
  evaporate.

5
Condensation

• Condensation is the changing of a gas into a
  liquid.
• When water vapor cools, the water changes form
  and becomes liquid water.

6
Condensation

• Clouds form as water vapor cools and forms water
  drops.
• Small drops bump into each other forming large
  drops.
• When the drops are too big and heavy, they fall
  as rain.

7
Precipitation

• Precipitation is water that falls to Earth as
  either rain, snow, sleet, or hail.
• Rain is just water drops falling down from the
  clouds.

8
Water Cycle

• The water cycle is the path that water follows as
  it moves from the air to the ground and back to
  the air over and over again.
• In the water cycle, water goes through
  evaporation, condensation, and precipitation.
