1. The Water Cycle Keisha Kidd, Curriculum Support Specialist Mary Tweedy, Curriculum Support Specialist Millard Lightburn, PHD Instructional Supervisor Division of Science Office of Academics and Transformation

2. Big Idea 7 Earth Systems and Patterns SC.5.E.7.1 (also assesses SC.5.E.7.2) 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. Pacing Guide 12/10 – 12/21 (10 days)

3. Item Specifications Benchmark Clarifications 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.

4. Water Cycle Water Cycle Evaporation Condensation Precipitation

5. Essential Question: What will happen to water in a cup if the cup is placed inside a sealed bag and left in a warm area?

6. Water Cycle Activity EXPLORE Essential Lab #8 Review (3 days)

7. Explain

8. Sun Heat from the sun changes water into water vapor

9. When the sun changes water into water vapor EVAPORATION

10. CONDENSATION When water vapor forms clouds

11. Rain or snow falls from clouds

12. PRECIPITATION

13. Water Cycle Song (to the tune of “She’ll 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.

14. Draw a model of the water cycle in your science journal. Label parts.

15. Compare you model.

17. True or False Water can be found naturally on Earth as a solid and a liquid, but not a gas. False The H 2 O 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

18. Review 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..

19. 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.

20. Enrichment / 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.

21. GIZMOS Water Cycle Control the path of a drop of water as it travels through the water cycle. Many alternatives are presented at each stage. Determine how the water moves from one location to another, and learn how water resources are distributed in these locations.

22. The Water Cycle never ends.
