The Mysterious Benedict Society
My favorite part of the book is when the Mysterious Benedict Society is sent to the Institute and they thought Mr. Benedict was the evil headmaster, Mr. Curtain. It turns out that Mr. Benedict and Mr. Curtain were twin brothers separated at birth because like the children Mr. Benedict did not have a family.
I didn’t think this book would be very good. Something just told me it would be boring and you had to have known a lot to understand it or something. I only read it because I can’t stand to see unread books on the shelf but when I started reading I went WOW!! I thought to myself, “Now I’m certain you can’t judge a book by its cover.” You can already tell I loved this book but just for the record, this book rates 5 stars with me.

AETRA Water Treatment Plant
Last Thursday Q-2 homeroom visited the AETRA water treatment plant. There we saw the 5 different steps the water went through to become potable and 2 other stations. They even showed us an animation at the end about water treatment. After the animation they asked 2 people quiz questions and I was lucky enough to get picked. My prize was an AETRA made raindrop plush toy. For a random reason Amalia and Saige named it Muffin Cheeks. The photo is of Muffin Cheeks. It was amazing the way they took fetid water from the local river and resurrected it.
First AETRA would run the river water through a series of what looked like large metal grates. The point of this was so large enough pieces of garbage would be trapped and not able to go through. To cleanse the grates of the trash every few minutes a gargantuan metal claw would lower down into the water. Then the claw would drag itself up against the grate taking any trash with it.
At the second station AETRA added alum a chemical that makes dirt particles stick together. When all the dirt coagulated it created foam called floc. The thing I thought that was cool about the first 2 steps was that there was no need to go scouring for trash or leaves. They just ran the water through grates and added alum.
The third station, I think was pretty boring. They just waited for the floc to the bottom of the water. But what they did with the floc was pretty cool. All the floc was recycled and turned into other objects such as tiles and bricks.
At the fourth station the water was ran through 1 meter of sand. It was like a giant sand filter, like the one in Bintato Lama. The sand they used though was not regular sand though. AETRA used a custom made sand that I believe to was made out of floc. What I couldn’t believe was that all the grains of sand were the same size and shape. They had to be! If the sand was just like regular sand you find on a beach the water would not be able to filter properly.
Then to finally make the water potable, and especially after sand filtering, chemicals were added. What I don’t get is why did they run the water through the sand? Why didn’t AETRA just add the chemicals? And 1 of the chemicals added to make the water potable is chlorine. Isn’t it bad for humans to drink chlorine?
The last stage that wasn’t really a stage was testing. Testing had to be done to make sure all the other steps had gone fine and the water was potable. When we entered the lab where testing was done the lab struck me as weird. It was full of test tubes and beakers filled with strange colored goop. It was like one of those old mad scientist labs on TV. Except it wasn’t place in a dungeon.

6 water questions pg.227
- What percentage of the world's supply of water is fresh water? Answer: Only 2.5 percent of the worlds water is fresh water.
- Where is the world's supply of fresh water found? Answer: The worlds fresh water comes from lakes, rivers, the atmosphere, the ground and some water is frozen.
- Even though the world's supply of fresh water is abundant it is still a problem. Why? Answer: Water availability is a problem because many places have more water than other places. For example Greenland has a large water availability per person because there is probably a lot of frozen water there.
- Observe the map of world average annual precipitation (Opposite).
(b) Describe the changes in rainfall that occur as you move from the western eastern tip of Australia along the Tropic of Capricorn. Answer: At the western tip it's pretty dry. As you start to move eastern it's still pretty dry but after a while it gradually starts to rain more. Until when your at the end where it rains day and night.
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? Answer: The places on earth which receive quite a bit of rain are Brazil, Indonesia, Southern China and a small part of Africa.
(b) Which parts of the world appear to have a small amount of water available per person? Answer: The places on earth that don't receive much rain are Greenland, Northern Africa and an area of Russia.
6. Observe the diagram of water use.
(a) What are the main uses of water? Answer: During the 20th century the main use of water was for Agricultural needs.
(b) Which uses have increased the most over the last century? Answer: There was a steep ascend in the 20th century for Reservoir losses from evaporation and seepage.

Bintaro Lama Field Trip
At my first station a Watsan member showed us how they found out if the water was clean. They especially reminded us even though the water was clean it did not mean it was drinkable. Water like this was used for washing clothes and such. The way we found out if it was clean or not is they would poor water into a tube and we would look inside through the top. If we could see the little X at the bottom it was clean.
At the second station they taught us how they cleaned the water. The water was ran through several layers consisting of gravel and sand, removing all of the BIG bacteria. The process is ran several times over and over again and then bacteria remover is added to make the water potable.
My final station was probably the most important. This was for people who didn't have bacteria remover. First you fill a container with CLEAN water. After the you put the container on the roof so it can boil for a few hours. During the boiling all the bacteria and germs in the water are killed and the water becomes potable.
We weren't gone from the school for long on the trip. But I bet that even if we were only there a few minutes we'd still see the circumstances some people have to live through. It just goes to prove that everyone who can go to school, have 3 square meals a day and have fresh water at any time should be very thankful.

Dear Mr. Hughes,
This video format is still QuickTime but in the lowest format. I believe there is a higher format possible but still meets your needs. If you want me to try the next highest format, please tell me.

Condensation, Evaporation, Precipitation and Infiltration
The below diagram shows infiltration. It shows how the water, after precipitation seeps into the soil until it reaches the saturated zone. I think this diagram is providing a little unnecessary info.
The picture below shows condensation. This photo is cut out from a bigger and much more complicated diagram. This photo shows after the sun is done evaporating water it forms clouds. When the cloud has enough water vapor in it, it will precipitate.
The diagram on the right represents evaporation. It shows the sun's rays evaporating the ocean transforming it into clouds. This diagram has just the right amount of info. It is also quite simple.
