Water travels in a cycle, yes it does.

Repeat above motion.

It goes up as evaporation,

Raise arms at side with palms up.

Forms clouds as condensation,Brings hands together above head, forming large cloud shape with arms.

Then falls down as precipitation, yes it does.Slowly lower arms at side with palms down, fingers moving.

True or FalseTrue or FalseWater can be found naturally on Earth as a solid and a liquid, but not a gas.•False

The H2O molecule consists of one Hydrogen atom, and two Oxygen atoms.•False

It takes a lot of heat, or energy, to change the temperature of water.•True

Water covers approximately 75% of the Earth’s surface. •True

Review QuestionsReview Questions• What is the role of the sun in the water

cycle? • Answer: The sun provides energy that

makes the water cycle happen.• How is water vapor created? • Answer: When the sun warms water it

evaporates. When it evaporates it turns into water vapor.

• .

• What happens to water vapor in the water cycle?

• Answer: Water vapor becomes part of the atmosphere. Then it cools and turns into liquid water or ice. The water or ice then falls back to Earth as precipitation.

• Where does water collect on Earth after falling from the sky?

• Answer: Water collects in the oceans. It also collects in other bodies of water and underground.

Enrichment / ExtensionEnrichment / Extension• Water acts as an insulator, keeping the Earth’s temperature and

weather patterns relatively stable. What property contributes to this? Imagine and discuss what would happen to our climate if the Earth wasn’t insulated so well.

• Water has been called the Universal Solvent. Talk about what that actually means, and how we observe this property in our own lives, every day.

• Although ¾ of the Earth’s surface is covered with water, only 3% of that is fresh water. The rest is salt water. Talk about the different sources we have for pure, fresh water. Also discuss the effects of human activity on our valuable water sources.
