Bintaro Lama Video

Hi on the 12th of November 2009 we went on a field trip to Bintaro Lama. We went there to learn how do they clean their own water. I went to three stations stations 1, 3, and 5. In stage 1 we learnt about Filtration in stage 3 we learnt about how to make clean water and in station 5 we learnt about Turbidity. I hope you enjoy the video.

WHY IS FRESH WATER SCARCE?

1. List the main reasons for water scarcity

Variations in climate, land degradation, population, growth and water pollution.



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 like no rain and it's dryness. They can't grow any plants because of dryness.

3. How does land degredation affect the supply of fresh water?
The soil is like a sponge keeping the rain.



4.

(a) What is El Nino?
El Nino is like a drought but it comes every 3 to 5 years in the Pacific Ocean of the cost of Peru. Then you get dryness. Then it won't observe the rain and it becomes flooding and it also causes drought.


(b) Why does El Nino often cause drought in Australia?
Because it goes the reverse way as a result there are no moist.


5. Observe the map showing the global effects of El Nino in 1982-83.

(a) What effects does El Nino have on the availability on fresh water?
It takes away the moisture and availability of water is greatly decreased.

(b) Name the countries and describe the problems that arose from decreased rainfall caused by El Nino.

Africa- Reduced corn crop in sub-Saharan region
China- Agricultural land under threat from drought in northern regions and flooding in southern regions.
Indonesia- High air pollution levels, following forest flies.
Philippines- Lower rice harvest following drought.
Papua New Guinea- Drought -related failure of food crops, leading to famine conditions requiring food aid.
Australia- Wheat exports threatened by drought conditions across grain-growing areas, particularly New South Whales.
Unite States- Rainfall above normal in north-western states (double the historical avaerages)
Colombia- Fishing operations affected by lower catch (down 20%)
Peru- Flooding (also in Chile) Fishing operators affected by lower catch as anchovy and Pacific sardine move offshore to escape warm currents (5 degrees C above normal temperatures)

Bintaro Lama Field Trip

Hi I went on a field to Bintaro Lama. We went in groups I was with Michelle Layanto and Sara Kausar. We went to stages 1,3 and 5.

In stage 1 we learnt about Filtration and how they clean their water. They have this big blue bucket and inside it there are small rocks. When the water is clean they don't use it to drink or to cook with it's actually used to take a bath.

In stage 3 we learnt how to clean the water bottle. This is the steps to clean it first

you wash the inside of the water bottle with soap next the outside with soap and then then the mouth part with soap. Next you wash it with water and rinse the inside and wash the mouth part again then fill the water bottle with water. Then you put it in the sun for about six hours and if the day is not sunny or it's going to rain then put it out for two

days. Then we get to try doing it.

In stage 5 we learnt about turbidity. I learnt that if you put the water in the turbidity meter you can see from the side that the water is totally clean but if you look in the turbidity meter if you can see the black X in the bottom that means that the water is clean but if you can't that means the water is dirty. Then we test it with a machine you put it in the water and if it says a number that is below a seven it is not safe to drink well

seven is safe to drink. In the PH scale 0 is Most acidic 7 is like safe to drink and 14 is Most basic.

This is what we learnt during that field trip it was fun you get to learn a lot of new things and from the Water Treatment I learnt new stuff too but going to Bintaro Lama is more interesting to me.

Water Activity

1. What percentage of the world's supply of water is fresh water?

2.5 percent.

2. Where is the world's supply of fresh water found?

On earth.

3. Even though the supply of fresh water is abundant it is still a problem. Why?

Because water and people are not equal.

4. Observe the map of world average annual precipitation (opposite).

(a) Describe the changes in rainfall that occur as you move from the southern to the northern tip of Africa.

In the southern tip of Africa there is a little bit then in the middle also known as the equator there is a lot and if you go a little bit to the northern the water will get less.

(b) Describe the changes in rainfall that occur as you move from the western to the eastern tip of Australia along the Tropic of Capricorn.

Well if you go to the west there is a little bit of rainfall.

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?

The north part of the world.

(b) Which parts of the world appear to have a small amount of water per person?

The east part of the world.

6. Observe the diagram of water use.

(a) What are the main uses of water?

For human living and the animals, plants and every living thing on earth needs water and has water.

(b) Which uses have increased the most over the last century?

The twentieth century.

Hi I went to a field trip to the Water Treatment in Jakarta last week on Thursday the 5th.It was fun and this is what we saw and learned.

In Stage 1 we saw a very big machine which used to separate the big trash from the dirty water. The trash is like black plastic bags, plastic water bottle, branches and etc.

In Stage 2 after they separate the garbage and dirty water, they add

minerals and they oxygenate the water. Before they put the minerals the water color is brown after that it became a little cleaner.

In Stage 3 they put Alum to make a floc for the small bits of dirt and it combines together like a magnet.

In Stage 4 the filtration of water treatment. They put 1 meter of sand into the dirty water in the pond. And

the sand settles down and it becomes a sediment.

In Stage 5 after they do the filtration

they also do the disinfection which the water has no bacteria and clean and it's gong to be brought to the lab and tested it.

This is the process of how dirty water becomes clean water. And the water that we use everyday. It is a lot of fun learning about it and you can see the process of it. It's amazing!

The Bad Beginning

*****

Lemony Snicket

This story does start with a bad beginning. As Mr. Poe told the Baudelaire children that their parents sadly died in a fire. The children have to stay with a very unpleasant man named Count Olaf which is now their guardian. Count Olaf can be nice in front of Mr. Poe or anyone else but he leaves the children some very hard chores like for example cooking dinner for Count Olaf and his theater troupe.

The children would have a very fun time with Count Olaf's kind neighbor named Justice Strauss and also reading in her nice library.

Count Olaf actually wants the Baudelaire fortune and to own it he have to marry Violet but Violet have to say "I do" in the marriage if she doesn't Sunny will be dropped from the tall tower but Violet did a smart thing she said "I do" but he also signed the form with her left hand she has to sign it with her right hand because she is right handed. Her marriage with Count Olaf is canceled. Count Olaf was supposed to be arrested but that didn't happen because he escaped with his friends. The Baudelaire orphans have no one to live with they were about to stay with Justice Strauss but she wasn't a relative so they stayed with Mr. Poe for a while but they don't know who are they staying with next anyways where is Count Olaf going? and what is he up to next?

My Poem

Hi I made this vedio and the poem is called I Remember. I really like this vedio and it's funny for me that's why I chose it.

Water

EVAPORATION

This is a picture of the water cycle but it also explains what Evaporation means. Evaporation means that liquid into gas.

CONDENSATION

The picture on the left is a picture of Condensation. Condensation is the opposite of Evaporation where gas turns into water.

PRECIPITATION

The picture on the right is a sample of Precipitation. It's a process of water descending to

the ground through the air and it came in a several forms as described beside.

INFILTRATION

The picture shows what Infiltration means. It happens when water seeps into the soil.
