3. Condensation When water vapor cools, it turns back into liquid to form clouds in the atmosphere. When the clouds get heavy, precipitation falls. Condensation can also be in the form of dew.

4. Precipitation Precipitation occurs when there is so much water in the air that it cannot hold onto it anymore. It will rain, snow, sleet, or hail.

5. Ground Water The earth soaks up some of the water, storing it in the ground until it is needed. This is called an aquifer. Many people pump water from an aquifer and use it for their drinking water.

6. Evaporation When the sun comes out and heats up the water, it turns into water vapor. This water vapor rises to form clouds.

7. Surface Water Precipitation fills up our lakes, streams, and oceans on the surface of the earth. Types of surface water include: – Rivers/Streams – Lakes – Oceans – Snowcaps – Icebergs

8. Surface Runoff When precipitation is not absorbed into the ground, it runs downhill to the nearest body of water. This runoff can be in the form of melted snow, rivers, and streams.

11. Assignment Objective: create a diagram of the water cycle. 1.For homework, take at least one picture to represent each step in the water cycle and at least two pictures of ways water is stored on earth. (At least six pictures total) 2.In class, we will print the pictures (or you may bring them already printed) and you will each glue your pictures onto a paper and label your water cycle.

12. Standard 1 : Students will understand that water changes state as it moves through the water cycle. Objective 2: Describe the water cycle. b.Describe the processes of evaporation, condensation, and precipitation as they relate to the water cycle. c.Identify locations that hold water as it passes through the water cycle. d.Construct a model or diagram to show how water continuously moves through the water cycle over time. e.Describe how the water cycle relates to the water supply in your community.
