Investigation 7: The Water Cycle

4. The Water Planet Looking at the globe:
Suppose that you are a visitor from another planet approaching the Pacific Ocean.
How would you describe the planet?
TG-P.234

5. The Water Planet
You may have heard of the Earth as being described as a water planet. If your first view of the Earth were the Pacific Ocean, it certainly seem so.
Of all the planets in the Solar System, Earth is the only one with vast oceans of water.
70% of Earth’s surface is covered in water
TG-P.234

6. Earth’s Water Inventory
Not all of Earth’s water is located in the oceans. Where are other locations for water on Earth?

8. Earth’s Fresh Water
Only a small portion of earth’s water is fresh water.
What do we mean by fresh water?
TG-P.234

9. Earth’s Fresh Water Fresh water contains no salt
Most of Earth’s fresh water is locked up in as ice in glaciers and in polar ice caps
TG-P.234

10. Earth’s Fresh Water
When you add the amount of ocean water and ice together, you find that 99.4% of Earth’s water is inaccessible to humans
How much of Earth’s water is potentially available?
= ???
0.6% of Earth’s water is available for human use
TG-P.234

11. Earth’s Fresh Water Look at the handout of Earth’s Water Distribution.
In what form is water found in the atmosphere?
Water vapor, ice, snow, hail, sleet, rain
In what form is water found in glaciers?
Ice, solid water
TG-P.234
Student Resource Book P.45

12. Earth’s Fresh Water What is groundwater?
Water that is found underground in spaces between rock particles, in cracks, and in other solid earth deposits
TG-P.235

13. Earth’s Fresh Water
In what form is water found under the ground or as groundwater?
Groundwater is mostly liquid, but some water might exist as ice if the ground is cold, or as water vapor in spaces between rocks and in soil
TG-P.235

14. Earth’s Fresh Water
Other than glaciers and icecaps, where else might fresh water be located?
Freshwater is also found in lakes, rivers, ponds groundwater, atmosphere and soil
TG-P.235

15. Earth’s Water Distribution
1. Fill a 1- liter (1000ml) beaker with water
- this is all of Earth’s water
2. Dip quickly and dry a pipette
- the trace amount of water represents all of the water found in rivers
TG-P.235

16. Earth’s Water Distribution
3. Put a little water in a pipette
Squeeze one drop into a cylinder
- The single drop represents all the water in Earth’s atmosphere
Squeeze 2 drops into a cylinder
- these drops represent the water in the Earth’s soil
TG-P.235

17. Earth’s Water Distribution
Squeeze three more drops in cylinder
- These drops represent all the Earth’s water in lakes and ponds
Squeeze three more drops into the cylinder
- these drops represent the water in all of Earth’s inland saltwater seas
TG-P.235

18. Earth’s Water Distribution
Measure 6 ml of water in a syringe, add to the graduated cylinder
- this 6 ml of water represents groundwater, the water in aquifers under the ground
Measure 21 ml of water
- this represents water frozen as glaciers and icecaps
TG-P.236

19. Earth’s Water Distribution
The volume in the cylinder is ~28 ml
How much water is left in the container?
1000 ml - 28 ml = 972 ml
The water left in the container represents the water in Earth’s oceans

21. Water Cycle Game
I want you to imagine that you are a water molecule about to enter the Water Cycle.
Each group of 3-4 represents 1 molecule
Look at the water posters
TG-P.236

22. Water Cycle Game Each group will begin in one of the nine locations:
animal atmosphere
glacier groundwater
lake ocean
plant river
soil
TG-P.236

23. Water Cycle Game Open the Lab Notebook to page 43 Jobs
The Roller- rolls dice
The Navigator - reads directions
The Scribe - records information
TG-P.236
Student Lab Notebooks - p.43

24. Water Cycle Game Rules Go to assigned Water - Location Poster
Record location, Roll a Die.
b. Find that number on the poster to determine where to move next.
c. Move, Record Information and roll the die again until you have rolled 10 times

25. Water Cycle Game Results
Project Transparency 24 Water Cycle Game Tally, record the total number of visits that each group had to each location
Record grand totals for section 2

26. Discuss Water Cycle
The results of the water cycle game present a picture of water molecules traveling through the environment in ways that are different from the picture of the water cycle that we are familiar with.
TG- P.238

27. Discuss Water Cycle
The water cycle shows water rising from the ocean and forming clouds, which move over the mountains and drop precipitation. The water flows to the sea and the cycle is complete.
TG- P.238

28. Discuss Water Cycle
How is what you learned from the Water- Cycle Game different from this “classic” water cycle?
TG- P.238

29. Discuss Water Cycle
In reality, some water does follow the classic cycle, but there are lots of other cycles too.
We saw water escaping from plants, condensing as dew, and going into soil, where it could be used again by plants.
TG- P.238

30. Discuss Water Cycle
Water vapor rising from the ocean condenses and precipitates right back into the ocean, never reaching land.
Water gets “stuck” in the ocean for a long time, never entering the water cycle at all.
TG- P.238

31. Discuss Water Cycle The water cycle is VERY complex.
The water Cycle is any movement of water that follows a path that moves water around Earth
Movement can take place between atmosphere and land, land and sea, and as a solid, liquid, or water vapor (gas)
TG- P.238

32. Discuss Water Cycle Movement can take place between:
Atmosphere and Land
Land and Sea
As a Solid
Liquid or Water Vapor
TG- P.238

34. Water Works Video Why is water significant to those who live on Earth?
All living things need water to survive. We use it for drinking, irrigation, recreation, transportation and electric power generation and we manage it for flood control
TG- P.238
Video- Water Works: Careers in Hydrology

35. Water Works Video What does the word Hydrology mean?
Hydrology is the study of water as it moves through the environment. It is understanding how water works and how it affects us
TG- P.238
Video- Water Works: Careers in Hydrology

36. Water Works Video What are the key elements in predicting a flood?
Knowledge of the amount of precipitation and runoff; the speed of the water; how much water to expect; the ability to follow water downstream
TG- P.238
Video- Water Works: Careers in Hydrology

37. Water Works Video
What might cause precipitation to run off into a river instead of soaking in?
Soil type, smooth or rough surface, amount of vegetation, steepness of slope
TG- P.238
Video- Water Works: Careers in Hydrology

38. Water Works Video What do hydrologists do?
Study the water cycle, gather data on precipitation, predict the speed of runoff and in rivers, predict river levels and floods and help emergency managers understand and anticipate hazardous conditions
TG- P.238

39. Water Works Video
What parts of the water cycle were shown on the video?
The amount available for use; precipitation, runoff, absorption by soil, vegetation and evaporation
