Purpose/goal of my PowerPoint

This project’s goal is for us is to study more about the water cycle. We want to show the young people after us about what we learn and the water cycle.

This water cycle picture represent that all the cycle that which its happen every year.

First the cycle can start everywhere but most the people start at the ocean because the ocean was the closes to them.

How does the water cycle goes?

Starting at the ocean, the water that storage in ocean start to evaporate from the heat of the sun which also can be call transpiration. It become condensation or a cloud and when the cloud get heavier and heavier it become a rain, ice or snow at the mountain which it call precipitation.

How does the water cycle goes?

When the precipitation happen the snow melt from the mountain. There are 3 way that water that melt could goes. First way you is to the surface runoff then it will went down to the ocean. Second way is it will goes underground then the water would initiation. It is the ground water storage then become a fresh water and goes into the ocean.

How does the water cycle goes?

The last way is the water that melt from the mountain will goes down to the stream. The water went down into the pond and that made the fresh water… that how the cycle happen and it will happen again and again.

Fresh Water

The fresh water that we use to drink is from the water cycle at the surface runoff or the underground water that became a fresh water by pond, lake, or stream. In our world is big but it is really less water in or world which about 1% of fresh water or 0.007%.

How much need?

For people a need person per day is attest 4-5 gallon per person, but the average of the American people they use attest 100 to 176 to survive per day. The average of Africa family, they use about 5 gallon for water each day.

Without food/water

A person can live a week without food, but they can live only three days without water. But some African can live without food for a month, but without water for only like normal people…3 days.

What’s happening in our world?

• Million of woman and children spend several hours a day collecting water from the distance.

• Every 15 seconds, a child dies from water related disease.

• 1.8 million children die each year from diarrhea- 4,900 death each day.

20 Way we could help to save the fresh water

1. Check for hidden water leaks.

2. Check your toilets for leaks.

3. Don’t use the toilet as an ashtray or wastebasket.

4. Insulate your water pipe.

5. Take shorter shower.

20 Way we could help to save the fresh water

6. Turn of water when you wet your toothbrush

7. Water your lawn when it needs it

8. Deep soak your lawn

9. Water during the early parts of the day.

10. Plant drought-resistant shrubs and plants

20 Way we could help to save the fresh water

11. Put a layer of mulch around trees and plants.

12. Don’t water the gutter

13. Don’t run the hose while washing your car.

14. Use broom, not a hose, to clean driveways and sidewalks

15. Check for leak in pipes. Horse, faucets and couplings.

20 Way we could help to save the fresh water

16. Never pour water down the drain when there may be another use for it such as watering plant or garden, or cleaning.

17. Retrofit all household faucets by installing aerators with flow restrictors.

18. If the toilet handle frequency stick in the flush position letting water run constantly replace or adjust it.

19. Use ultra-low-flow version.20. Don’t leave the tap open.

Vocabulary

1. Evaporate/transpiration: Evaporation is when the sun heats up in river or lakes or ocean and turn in vapor or stream.

2. Condensation: Water vapor in the air get cold and change back into a liquid, forming cloud.

Vocabulary

3. Precipitation: Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail,sleet, or snow.

4. Collection: When water falls back to earth as precipitation, it may fall back in the oceans. Lakes, or it may end on land.
