1. Do Now:
While watching the following movie clip answer the following questions on your worksheet.

2. Turn and Talk:
Will the world always look the way it does today? Explain.

3. Learning Objective:
I will be able to explain the processes involved in the water cycle. I 

4. Success Criteria:
1) I can explain how much water is available on Earth. 2) I can identify the places in which freshwater is located. 3) I can explain the difference between condensation, evaporation, and transpiration. I 

5. Water on Earth
How much of our planet is covered by water?

6. Water on Earth
Oceans cover nearly 71 percent of Earth's surface. .

7. Most of Earth's water—roughly 97 percent—is salt water that is found in the oceans.
Can we drink this water?

8. Eventually, we harvest that salt for our use!

9. Only 3 percent is fresh water.
Of that 3 percent, about three quarters is found in the huge masses of ice near the North and South Poles.

10. Water on Earth A fraction more is found in the atmosphere.
Most water in the atmosphere is invisible water vapor, the gaseous form of water.

11. Water on Earth
Less than 1% of the water on Earth is fresh water that is available for animals to use.

12. Water on Earth

13. Check for understanding: I can interpret a chart to determine how much freshwater is available.

14. Water on Earth Types of water on Earth Oceans Ice Rivers and Lakes
Below Earth's Surface  
Groundwater: Water that fills the cracks and spaces in underground soil and rock layers .
Most fresh water is located underground.

15. Check for understanding: I can identify where freshwater is found on Earth.

16. The Water Cycle Water is naturally recycled.
A continuous process by which water moves through the living and nonliving parts of the environment.
The sun is the source of energy that drives the water cycle.

17. The Water Cycle - Energy from the sun drives the water cycle.

18. The Water Cycle Water is constantly moving between sea, air and land
The sun shines and the sea is heated
heat

19. Evaporation: Liquid water to Water Vapor (Gas)
The water evaporates and forms clouds
Evaporation

20. Condensation: Gas to liquid forms clouds
As air rises it cools and condenses. It reaches the ground as rain, snow, sleet or hail.

21. Precipitation: Rain, snow, sleet, hail fall to the ground.
Snow forms
Lakes form
The snow melts and flows
Rivers flow to the sea

22. Infiltration: Water seeps into the ground
Snow forms
Lakes form
The snow melts and flows
Rivers flow to the sea

23. Runoff: Water runs off the surface into the oceans
Snow forms
Lakes form
The snow melts and flows
Rivers flow to the sea

24. The Water Cycle Water is constantly moving between sea, air and land
The Water Cycle is complete

25. Check for understanding: I can explain the processes involved in the water cycle.

27. The Water Cycle Steps of the Water Cycle Water Evaporates Clouds Form
Water Falls as Precipitation  
And then it starts again

28. Summary:
Write an explanation of the water cycle beginning with two drops of water in the ocean. You must use key vocabulary words (evaporation, precipitation, condensation, etc).

29. Water Evaporates Evaporation: Liquid to gas
Water can evaporate from where?
Ocean
Lakes
Soil, puddles, and even from your skin
Plants
Eventually the water is given off through the leaves as water vapor in a process called transpiration

30. Condensation: Condensation: water vapor to liquid water
Condensed droplets of water clump together around tiny dust particles in the air, forming clouds

32. Water Falls as Precipitation
As more water vapor condenses, water droplets in a cloud eventually become so heavy that they fall back to Earth.
Water that falls to Earth as rain, snow, hail, or sleet is called precipitation.
Most precipitation falls directly into the oceans.
Precipitation is the source of all fresh water on and below Earth's surface.
The water cycle renews the usable supply of fresh water on Earth.

34. The Water Cycle

35. Do Now:
How much water do you consume each day?
Be specific.

36. Turn and Talk:
What are ways in which we could reduce our water usage?

37. How Do People Use Water?
The water people use at home is just a small percentage of all the water used in the United States.
In addition to household purposes, people use water for
Agriculture
Industry
Transportation
Recreation

38. Agriculture Farms need a constant supply of fresh water
Irrigation is the process of supplying water to areas of land to make them suitable for growing crops.
In the U.S., more water is used for irrigating farmland than for any other single purpose.

39. Industry What objects require water to produce them?
Water is needed to produce most objects.
Water plays a role in the industrial processes that created them.
Power plants and steel mills both need huge volumes of water to cool down hot machinery.

40. Transportation
Oceans and rivers have been used for transporting people and goods since ancient times

41. Recreation
Swimming, Fishing, Going to the beach, skiing, snowboarding, Water park etc.

42. Water Usage

43. Summary:
Based on your knowledge on water usage, Do you think we use water sustainably or do we waste water?
Explain your answer using evidence from what you learned in class today.
