Big Idea 7: Earth Systems and Patterns

The Water CycleSC.5.E.7.1 Create a model to explain the parts of the water cycle. Water can be a gas, liquid, or solid and can go back and forth from one state to another. (also assesses SC.5.E.7.2)

• Students will identify and/or explain the parts of the water cycle.

• Students will identify the states of water associated with each part of the water cycle and/or the phase changes that occur as water moves from one part of the water cycle to another.

• Students will identify and/or describe the role of the ocean in the water cycle.

The Water CycleWhat are the three main processes?

•Evaporation

•Condensation

•Precipitation

• Heat from the sun changes water into water vapor


What is the process called when the sun

changes water into water vapor?

EVAPORATION


CONDENSATION

What process is it when water vapor forms

clouds?


Rain or snow falls from Rain or snow falls from cloudsclouds


What is precipitation?

Water Cycle SongWater Cycle Song(to the tune of (to the tune of ““SheShe’’ll Be Coming Around the Mountainll Be Coming Around the Mountain””))

Water travels in a cycle, yes it does.

Use pointer finger to draw large circle in air.

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 False1. Water can be found naturally on Earth as a solid and a liquid, but not a gas.•False

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

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

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


Review QuestionsReview Questions1. What is the role of the sun in the water cycle? •Answer: The sun provides energy that makes the water cycle happen.

2. How is water vapor created? •Answer: When the sun warms water it evaporates. When it evaporates it turns into water vapor.•.


4. 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.

5. 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.


Brief Constructed ResponseBrief Constructed Response

Describe one path water can take through the water cycle. Begin with water that falls to Earth as rain and end with water in clouds in the atmosphere.


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.
