Ski
Today was the most exciting day during the winter break. Me and my family went skiing to YONG PYUNG skiing resort. First we packed our bagages for 2-days schedule. Then me and my brother rushed outside to borrow a ski for today and tommorow. I could tell my brother was also very excited because he forgot to wear his socks before he put his shoes in. When we were prepared and everything, we went on sky lift to take us up on the slope. Now that I was at the top, I took a deep breath and SHOOSH~ The feeling I had during the short ride was unexplainable. I dont know but I think it was a mixture of thrill, and trepidation. I drew an A sign with my feet to stop at the end. The moment I finally stopped, it was just AWESOME.

battle of the labryinth
Battle of the labryinth (Book 4 of Percy Jakson series)
By Rick Riodran
Rating: *****
I finished the book Battle of the labryinth almost 1 month ago. I guess I didn't blog about books too much and forgot about it. Anyway, since I have the whole time to myself, I thought I might just post about the book now.
As I mentioned above, this book is the 4th book of Percy Jakson series. I've done a blog post about the 3rd one, the Titan's curse, so you might know what this is about. But for other people, this book is about greek mythology. There are gods, and olympus. Some of you might know about this because well, greek gods are famously known around the world even to the western side. Anyway, there is our hero Percy. He is a son of Poseidon, who is the sea god. In this book, he and his friends; Annabeth, Grover and his half-brother cyclops, Tyson. Together they plunge themselves into the darkness of the Labryinth, which is a maze that can never be solved. In the journey, they meet the wild god, Pan, and they manage to hold off the attack of the mighty Titans, but there are more and more coming endlessly.
My favorite part of this book is when Percy fights the telekhies, who are sea demons. In this part, he uses the power from his father, and brings up a huge tidal wave to the demons and destroy them. Here every telekhies dissolve into nothing, (by the way, when monsters get killed, they discinegrate). This was so cool because this was like about the 1st time he actually used his most powerful ability, which explained him passing out for a week.

Geo skills
1. List the main reasons for water scaricity.
Answer:
-Hot places like deserts have low rainfall.
-Land degradation
-The variations in climate
-Population growth
-Water pollution
-Arid areas have average rainfall below 300mm each year.
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?
Answer:
Drought is when there is less precipitation than usual. Droughts can cause many death to people due to thirst.
3. How does land degradation affect the supply of fresh water?
Answer:
If the land is paved off or damaged, this can cause problems for the groundwater storage under the ground which is all drinkable. Therefore, the ground won't be able to absorb much of the heavy rainfalls and there will be a lack of groundwater storage.
4.
(a) What is El Nino?
Answer:
A warming that happens in the Pacific Ocean off the coast of Peru. El Nino happens every 3-5 years or so.
(b) Why does El nino often cause drought in Australia?
Answer:
During El Nino, the moist blows to the pacific ocean reverse their direction. This process is accompanied by a reversal air pressure from across the pacific, resulting in high pressure systems over Autralia. This prevents the moist tropical air masses reaching Australia.
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?
Answer:
El Nino creates a heavy rainfall that might lead to serious floods. When floods occur, these effect the availability of fresh water because the water gets polluted and therefore there is a very little amount of fresh water left.
(b) Name the countries and describe the problems that arose from decreased rainfall cause by El Nino.
Answer:
-Australia: Serious droughts.
-Africa: Reduced corn crop growing.
-Indonesia: High pollution level in the air due to forest fires.
-China: Land in threat due to droughts and floods.
-Papua New Guinea: Unable to grow crops because of droughts.
-Peru: Flood. Lower catch of fishing as anchovy and pacific sardline move offshore.
-Colombia: 20% decrease in catching fish.
-United States: Average rainfall exceeds. (Double the historical averages)
Answer:
-Hot places like deserts have low rainfall.

About putting power point on the blog+
any1 know how to put a power point on a blog? somebody tell me PLEASE!!
Bintaro Lama field trip
My homeroom classmates rode on the bus to make our way to Bintaro Lama, which took us about 35 minutes or so. I was pretty excited, because I was eager how people there cleaned their water and I also wanted to see the enviroment if it was clean or not. In this blog post, I will write about 3 stations where me and my partners (Si won and Brandon) got to look at.
The first station, which was station #6, we learnt 2 ways to disinfect water and make the water potable. The guide showed us a tablet called Aqua tabs. 1 or 2 tablets can clean 30L of water at once. Now thats what I call awesome. What they do is that they will add the Aqua tab and let it dissolve. This process doesn't take very long, so it is a proficient and fast way to get access to clean water. Another method, is adding a liquid called Air Rahmat. By 5 ml of this liquid is about enough to purify 1 gallon of water. However, after pouring Air Rahmat, you will have to shake it at least 30 seconds.
The second station was station #2. In this station, we learnt the whole infrastructure of how food gets contaminated. They told us that after pooing (^_^) , they clean it with tissue and some don't wash their hands after it. Then the bacteria in the fecus gets on their hands and when they make food or touch the food, the food will get contaminated and it can give you a really bad stomachache. After learning about that, the guide told us about 5 ways to prevent that. One of that was building a proper toilet, which made pretty good sense to me.
The last station was station #4. This station was very interesting, because they had the same idea of cleaning water in the water treatment plant I went to, but a miniature version of it. First, they put a liquid called PUR, which helps the dirt particles to stick together and form a flock. Then the sedimentation begins. The flocks fall down to the bottom of the water, settling down there. Another way was filtration. They used a big bucket with a clay pot in it, and they lay pieces of cloth on the pot. What happens is that when dirty water goes through, the garbage and all the big trashes are left behind the cloth. Very interesting, because they had the same idea in the water treatment plant.
I think it was pretty cool to visit a kampung like this. Well, there were a lot of trash and bugs, but there were really friendly and kind people which put me under no pressure of asking any questions. Oh and at the end, they taught us a caroll that tells about washing your hands. It followed the rythm of 'If you're happy and you know it clap your hands', so I though it was another cool activity they prepared for us.
