Science- Class response

In class we have been making websites about the roller coaster we created with our groups. This was a learning experience for most of us since we learned how to use our money wisely(when buying supplies) and how to create a website. Our website advertises the small business we create and also talks about how roller coasters applies to Newton's Laws of Motion.
The first law of motion relates to roller coasters because it talks about how objects at rest stay at rest until an outside force moves it and how an object in motion stays in motion until an outside force stops it. For example, a cart on a roller coaster will never start until a force pushes it and the a cart on a roller coaster will never stop until something stops it.
Sir Isaac's Second Law of Motion shows how mass, force and acceleration are related. The formula used for this is force=mass X acceleration or F= M x A. An example of this is when your going up a hill. More force is required in that the going down a hill because when down a hill gravity pulls you down but when going up a hill more force is required because gravity is preventing you from going up.
The third law of motion states that for every action, there is an equal and opposite reaction. When there are sharp turns while you are riding a roller coaster, you jerk a little to the opposite side.

Social Studies- International Current event

baby rhesus monkey by Stella Solaris. Baby Rhesus by Chi Liu.

To get rid of the countless number of monkeys in Puerto Rico, they have decided to ship them of to Iraq and reduce the 2,000 patas and rhesus monkeys. In 2003 looters had kidnapped or set free all the animals is the Baghdad Zoo and America has paid over 12.5 million to build agian. Because of the numerous number of excess monkeys in Puerto Rico, officials have been shooting nonnative monkeys and they are very happy to contribute to the Baghdad Zoo. Some of the other monkeys are put up for adoption but because they are such a big nuisance no one wants to adopt them. But the monkeys aren't save in Iraq either. Because of the war between America and Iraq no one has time to pay attention to animals and care for them. In my opinion, the monkeys are better off in Puerto Rico becuase there they can be with their friends and family and not be trapped in a cage.

Recently in class we learned about Sir Isaac Newton and the three laws he developed about the states on motion. These laws show how motion is caused by a force or forces. The first law of motion states that an object at rest will always remain at rest and an object in motion will remain in motion at constant velocity unless acted upon by an unbalanced force. Sir Isaac called "the tendency to remain in motion of rest" inertia. The first laws also tells us that acceleration and force are related because if an object wants to accelerate a force needs to push it. An example of this could be if you a throw a bowling ball with the same force you throw a tennis ball, the tennis ball will go farther because it has less mass.
The second law of motion talks about how acceleration and force are related. It shows how more heavier objects or objects with more mass move at the same distance as lighter objects or objects with less mass. The formula that Isaac come with for finding out the force is force= mass multiplied by acceleration. For example, if you are trying to push a car, which will cause it to accelerate, and then you push 5 times harder then how much the car move will be 5 times faster.
The third law of motion states that for every action, there is an equal and opposite reaction. An easier way to understand this is that all forces come in pairs. An example of the third law of motion is when a space shuttle takes off into space because it pushs downward but goes upward.

Social Studies- earthquake in New Jersey

Filename: j0153602.wmfKeywords: buildings, earthquakes, homes ...File Size: 27 KB
On February 02, 2009 there was a minor earthquake in central New Jersey. Yes you read it right!!!! There was a earthquake in New Jersey!!! We usually hear about earthquakes happening on the west coast but there was one right here in out home state!! Won-Young Kim, a scientist at Lamont-Doherty Earth Observatory, said that the earthquake happened at 10:34 and had a preliminary magnitude of 3.0. Even though no one got hurt the earthquake caused some panic and many calls were made to 911. Many people thought that there was an explosion or a bomb went off but police officers reassured everyone saying that it was only a minor earthquake. When I first heard about the earthquake in New Jersey i was really surprised because I didn't think that earthquakes could happen in New Jersey but i was also thankful becuase it wasn't a really big earthquakes and no one got hurt.
