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.

|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.

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.
