The Last Summurai

There are a lot of themes in the movie the last summurai. I think one of the best theme is belief in causes. It tells us that everyone who live has a goal to live. I think this is really important. People live on the earth should have a destiny of doing something.
The other important theme is be proud of who you are. I think everyone should be proud of who they are. Everyone on the earth is a unique person. No one is a exact same person as others, so everyone should be proud of themselves.

newton's law and Kinetic friction and Static friction

The example I saw for newton's first law is the rolar-coster. When the rolar-coster stop immediately, you will feel that you are going to fly out. Because a moving object tends to stay moving.

I also saw an example for newton's second law. I saw two pirate ships at friday. according to newton's second law. It tells us that a machine with a bigger mass needs more energy than the small one. The bigger the pirate ship is the more energy it needs to move it.

I saw an example for kinetic friction, which was when the rolar-coster stopping. Its wheel slowing it down provide kinetic friction to make the rolar-coster stopped.

An example I saw for static friction is the pirate ship. Enable to let the ship move, the machine have to provide a power over the static friction of the pirate ship, so it would move.

Current Events: Climate Change

In this current events pointed out that, the scientist predicted, because of global warming, the rain fall in South Africa will decrease dramatically. This is going to caused serious drought is South Africa, and people are going to be thirsty. Not only will the rain fall will decrease in certain area, but in some area, will have too much rain fall. Places like india, Srilanka, ... the rain fall will increase dramatically. Global warming is going to cause serious problem on the earth.

Why is a drawing a sketch an important part of the scientific method and why do you always neglect this step!?!?

I think drawing a sketch is important. It gives you a better idea of understanding the question. Drawing a sketch also gives you a better idea of what you are building. When you draw out a sketch you know which direction you are going, and then you can work faster and better while you are doing the project. I think sometimes we neglect this step, because some times we don't fallow the sketch that we draw, because the sketch it self is too hard to be built. And sometimes we just want to built it first then fix it later.

Jaguar Paw

After the jaguar paw go into the forest, they were really tired. They walked for a long time in the dark rainy forest. When they were hungry, the jaguar paw hunted several rabbit to feed the family. After a few days of walk, they saw a village. Around the village, they saw a lot of starving people. They were all hungry and sick, because of the diseases that the Spanish brought. Jaguar Paw and his family try to keep in distance with the villager, because they are afraid to get the diseases getting too close. Disappointed and depressed, the Jaguar Paw and his family have to move on.
They climb over mountains and cross over rivers. One day, Jaguar Paw heard a loud noise in sleep. He woke up immediately, and tell his family to hide in the caves. He went out try to find out what is happening. He hide in the woods and glimpse out. He saw a troop with weapons that he never saw before chasing the Mayas soldiers. He saw the mayas soldiers die without being touch. He was really frighten and scared. Then he saw the clothes that the Spanish wear is extremely hard, the Mayas try to kill them with their sowards and spears, but it just doesn't work at all. The saw hundreds of mayas being killed and shot. He sprint back to the cave, and tells his family to run quickly, because the spanish is coming towards them. The Jaguar paw carries his two sons and run as fast as he could. His wife fallows behind them. They heard the gun shots and people yelling behind them. They run faster. After a running for a day, they were really tired and fall a sleep.
When the Jaguar Paw and his family woke up. They were on a bed. Jaguar Paw sits up, and discovered that they were in a village. The people in the village were happy and healthy. Jaguar and his family then settle in that village for the rest of his life, living happily ever after.

The climate change

The climate change on the earth, had effect on the number of birds coming to Taiwan. because the climate is getting hotter and hotter in Taiwan. Taiwan is no longer a capable place for the birds, so every year the number of birds coming to Taiwan is decreasing. I think we have to react to this problem fast, or else maybe one day Taiwan will be as hot as the equator.

Compare and contrast maya technology and other civilization

I think the biggest differences between the mayan and the other civilization, is that the Mayans had city states, which the other civilization don’t. the Mayans had a lot of different cities and they were all called the Mayas, but the other civilizations almost only had one city. I think this is one of the biggest difference between the Mayas and the other civilizations.
Some of the similarities including the technology they develop, and the irrigation system, and the government. They are all some kind similar.
