5th Grade-Week 4 Water Cycle

Objective: 
Students will learn how a water molecule can change from a liquid to water vapor and back to a liquid.


Students will learn how a water molecule moves throughout our planet in the Water Cycle.


CA Science Standard ES3b
Students know when liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water.
Vocabulary:
evaporation
condensation
precipitation

Warm Up:

What is the water cycle? 
Discuss, draw pictures, and write down ideas

•What are the three parts of the Water Cycle?

•What is evaporation?

How can we conserve water at home?
Most of the fresh water in California is used for agriculture or farming.
The Water Cycle



Review the parts of the Water Cycle:

•Evaporation is when water heats up and changes into water vapor.

•Condensation is when water vapor cools and changes back into water on a surface.


•Precipitation is when water falls back to Earth as rain, snow, sleet or hail.

CA State Science Standards
3a. Students know most of Earth’s water is present as salt water in the oceans, which cover most of Earth’s surface.
3b. Students know when liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water.

3c. Students know water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or snow. 3d. Students know that the amount of fresh water located in rivers, lakes, underground sources, and glaciers is limited and that its availability can be extended by recycling and decreasing the use of water.
