1. List the main reasons for water scarcity.

Because some people lives in hot desserts which has very low rainfall. Other reasons are 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 a period of below average precipitation.

3. How does land degradation affect the supply of fresh water?

It reduces the soil to store water.

4.
a) What is El Nino?

Wind that happens in 4 or 5 years

b) Why does El Nino often cause drought in australia?

El Nino makes air masses making Australia getting drought.

5. Observe the map showing the global effects of El Nino in 1982 - 83
a) What effects does El Nino have on the availability of fresh water?



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

Peru:Flooding. Colombia: Not getting fish. Australia: Wheat exports threatened. Papua New Guinea: Drought. Indonesia: Air Pollution causing fire. China: Drought in the north and flooding at the south. Philippines: Lower rice harvest. Africa: Reduced corn harcesting. US: More Rainfall.

Bintaro Field Trip Video

This is a video about Bintaro Kampung and how they clean water:

Wish you like it : )

Bintaro Kompung

As I took the video for the route, Mr. Hughes talked to us about the river. As we got of the bus we were welcomed by he people of Watsun. They did a little speech then we headed of to station 1 with our guild.

Station one is about FILTRATION, there is a blue bucket, one of those tall and round ones, in the bucket there is sand, gravel and stones, they use the pump to pump up water from the ground then a pipe leads the water to the filter, after the water goes down the filter it will be safe to shower and cook with but NO DRINKING!

As we finished up with some questions we moved to station three, UNINFECTION. The host cleaned the big size Aqua water bottle until germ free and then we fill it up until there is not space or air bubbles in side. Then we put it under the sun for more than 7 hours, and now it is save to drink.

After all this stations how do you test the water? This job is for station 5, we tested how clear the water is with a tube with numbers and a "X" under the tube. The smallest number the tube but is the highest number is 5 and the biggest number but the lowest on the tube is 500. The way you test it is to pour water until the water reaches 5 then you look through the tube on the top to see if you can see the cross, if not pour some out until you can see the cross. The smaller the number the better. To test the pH of the water they have a little orange machine that looks like a thermometer, the pH scale is between 1 to 14, the best is 7 if too low is acid too high its alkaline.

After the 3 stations the kids sang a song to us. A short and cute song about washing your hand.
I felt this is a super-ichy-fun-tiring trip, I loved it.

Stephenie Meyer

***************

Vampires, love and high school, when you here this word you can't really connect them together, but this is what Stephenie Meyer did. She wrote so well that I gave this book a 15 star rate. As you found out in the beginning this book is about vampires, but it is not scary. A girl fell in love with a vampire, the vampire told her the secret, and this is what is book is all about.

My favorite part is where Stephenie was describing the Cullens. The factual expression, the look and what they were doing. she did a pretty good job on that.

*****

Is alien really real, or is it just a make believe. Well in this book, Jason finally meets his love when he found out that he is an alien from outer space that is trying to conquer the world.

My favorite part at the very end, where a guy asked: "What's your name and what are you."

Jason replied: My name is Jason and I am a human." This really shows almost all the feelings he had through out the book. at first he is just a kid who had a crash on a girl, then he found out that he is an alien which he wished he is not. And in the end where he says that he is going to be a human.

Activities:

Q: What percentage of the world's supply of water is fresh water?

A: 2.5% of world's supply is fresh water.

Q: Where is the world's supply of fresh water found?

A: 2% is in the form of ice, .49% is found underground and 0.01% is found in the atmosphere, rivers and lakes.

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

A: The water is not equally shared so some place they have much more than what they need and some place they have too less.

Observe the map of world average annual precipitation (on page 226).

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

It first start off with under 250mm then is whent to 1000mm to 1500mm, at last it went back to under 250mm of water.

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.

It started off dry then when you at almost the eastern coast it there is more rainfalls

Observe the map on page 227 of water availability per person.

a) Which parts of the world appear to have a large amount of water available per person?

The northen part and the south-east part of the world.

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

Mostly at the Tropic of Cancer.

Observe the diagram of water use (on page 227).

a) What are the main uses of water?

The water is mainly used for farming.

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

The industries increased the most over the last century.

The Water Treatment Plant

As the buses drive slowly across the river and complained about the rubbish in the river. There was cans, bottles and a lot other stuff. For a river it is pretty yellowish.

The buses stooped at a building about the size of our New Gym. Our class got off the bus and went with a guild. We walk up hill and arrived at stage 1 - Filtration. This is where the water flows in from the yellowish river we talked about in the front. They have metal bars, from big to small, used for collecting garbage and not useful things.

Next stop we went down stairs and came in front of a big room, this is for aeration, we couldn't go in so all we could see is pipes and people.

After some more filtration we have stage 3, coagulation : where they add alum to make floc, the thing when dirt comes together and become bigger.

Fourth stage is sedimentation, because the big pieces of floc is to heavy for the surface tension, it drops, which is sent out and into a storage room for dirt, useful for planting and things like that.

The last stage for water treatment: Disinfection, with the disinfectant killing germs it is almost safe to drink. It needs to go to filtration again but with fine and same - size sand. To make sure every thing is fine to drink the worker takes water sample and test it.

In the end we watched a video. It is all about this water treatment. After seeing sample of the river water before it comes in to the water treatment plant and after, you can see a huge difference. A yellow and a see - though, how cool is that!

The Water Cycle

Evaporation

---

As you can see in this picture, the water turns into water vapor and goes into the air.

Condensation

---

After the Evoration, the water vapors gathers together and forming clouds, like the white things on this picture.

Precipitation

---

On the top of the picture there is a mountain, which makes me think that this rain is caused by orographic precipitation - the mountain forcing the air to rise and causing rainfall.

Run-off & Infiltration

---

In this picture, a part of the rain water soaks in the ground and becomes ground water, after that it flows to a lake. The other part of the rain water that didn't soak down the ground flows in the river.
