This is a movie I made that is based on the field trip that we attended on the 12th of November 2009. Enjoy the video!

Water Questions 2
1) List the main reasons for water scarcity.
The main reasons for water scarcity are Land Degradation, Variations in climate, Water pollution and Population growth.
2) What is a drought? What type of hardships do you think that a drought could cause if you were living in a village in a poor country such as Ethiopia?
A drought is a time of less average precipitation.
3) How does land degradation affect the supply of fresh water?
Because land degradatoin infects the fresh water, so we can't drink it.
4)
(a) What is El Nino?
El Nino is a warming that developes every 3-5 years.
(b) Why does El Nino often cause drought in Australia?
Because El Nino is accompanied by reversal of air pressure across the Pacific Ocean, resulting high pressure building up over most of Australia.
5) Observe the map showing the global effects of El Nino 1982 - 83.
(a) What effects does El Nino have on the availability of fresh water?
It blows all the water on land.
(b) Name the countries and describe the problems that acrose from decreased rainfall caused by El Nino.

Bintaro Lama Field Trip
On the 12Th of November all of the 6Th graders went on a field trip. Some of them went to the water treatment plant, and some went to the Kampung, we went to the Kampung. What really touched me was that, we don't have to worry about water. It just comes to our homes, but for the Kampung people they have to get the water from the dirty river, and clean it themselves! It never occurred to me that how lucky we are to have access to fresh water whenever we want, with no trouble! We split in about 6 groups, and each group saw a station at different times, it really taught how to clean dirty water to clean water. We went to stations 6, 2 and 4.
Station 6 -
Station 6 was adding and shaking chemicals. In this step they add the chemicals, which can be held in a small tablet or a liquid, so that the water is clean.
They shake the water for 30 seconds, non-stop so that the liquid or tablet has spread through out the water. The tablet will begin to dissolve the lounger you have it in the water. Once youfinish shaking it for 30 seconds the water should look see through, and is now SAFE to drink.
Station 2 -
Station 2 is Public Health Promotion.This is where they teach the children how to stop water disease transmission. This step is broken into pieces.
This is how you stop water disease transmission -
1.
2. Make a toilet, people need proper toilets with septic tanks.
3. Cover your food, if you don’t cover your food flies will come land on it, and who knows where they’ve been.
4. Use aqua taps and Rah mat air.
What is Aqua taps? Aqua taps is a tablet. You can use 1 tablet for 20 liters of water in normal condition, and in extreme condition you can use 1 tablet for 10 liters of water.
Station 4 -
In station 4 you do Flocculation, Sedimentation and Filtration. Flocculation is when you mix the flock with a chemical and then mix it. Sedimentation is when the flock sinks to the bottom, and filtration is when the water filtrates through the clay pot
The ride back to Cilandak was hilarious!!! I bet Val and Maya that I could finish a whole Isotonic bottle with out putting my mouth of the bottle, and of course I succeeded!!! Then Maya tried and Val played the "Peanut Butter Jelly Song"and Maya bursted into laughter! All of the water that she spat out landed on my knee... Eeeewww!!!
I've learned that not everyone around the world has access to water, and I've learned how to turn dirty water into to clean water.

Water Questions
1. What percentage of the world's supply of water is fresh water?
There is 2.5 percent of fresh water on earth.
2. Where is the world's supply of fresh water found?
I think the world's supply of fresh water is mostly found in the United States.
3. Even though the supply of fresh water is abundant it is still a problem. Why?
Yes there is a problem, because water is the most abundant thing on earth, but people need fresh water. And only 2.5 percent of fresh water is on earth!
4. Observe the map of world average annual precipitation (opposite).
a) Describe the changes in rainfall occur as you move from the southern to the northern tip of of Africa.
On the bottom of Africa there is a little more rain than the top of Africa.
b) Describe the changes in rainfall that occur as you move from the western to the eastern tip of Australia along the the Tropic of Capricorn.
On the eastern side there is much more rainfall than on the western side.
5. Observe the map above of water availability per person.
a) Which parts of the world appear to have a large amount of water available per person?
Most of the northern side has a lot of water per person.
b) Which parts of the world appear to have a small amount of water per person?
On the west side there's not much water available per person.
6. Observe the diagram of water use.
a) What are the main uses of water?
The most use of water is on Reservoir losses from evaporation and seepage.
b) Which uses have increased the most over the last century?
The Industrial, Community and Reservoir losses from evaporation and seepage seem to have increased a lot over the century, because they are very steep.
There is 2.5 percent of fresh water on earth.

Water Treatment Steps
You can really see the difference between clean water, and dirty water. First of all clean water is tasteless and odorless.... And dirty water is yellow! Plus you can totally smell the dirt that's in there, and it tastes disgusting!!! SO DON'T TRY IT!!!
STEP 1 - Taking the big pieces out of the water
In this step they have these huge things that block the big trash from getting in. Now this step ONLY stops the BIG pieces. When there is a big piece it will get caught in one of the things that dig into the ground and then just stay there. It won't just go away. Someone has to take it out, otherwise it'll just stay in the water, until someone takes it out. It looks really grouse, because all the other stuff just flows into there, and let me tell you, there's some really nasty stuff flowing in there!
STEP 2 - Aeration
Aeration means that they have to poke a hole into the ground so it allows air and water penetrate the surface of the soil. The area is top dressed afterward and sand fills the holes to prevent closure.
STEP 3 - Adding Chemicals
This is an important step of the process. This step is when they have to add all of the chemicals, so that the dirty stuff floats up to the surface.
STEP 4 - Sedimentation
Sedimentation is used to settle out solids in water under the influence of gravity. In sedimentation there are 4 steps.
Step 1 - Is when every particle settles independently.
Step 2 - Is when the particles flocculate as they settle.
Step 3 & 4 - Is when the sludge is thickening.
STEP 5 - Filtration
Filtration is when is passing through a filter.
The trip to the Water Treatment Plant was very cool. I got to learn so many more things about water than I knew at the beginning. In all there are 5 steps.
I thought this trip was really great. Although I must say everyone had sweat dripping down their chins. Sorry that there's not so much of an explanation for filtration. But I think everyone should understand.
