You may not realize it but wind plays an extreme role in our lives. Depending on the direction the wind is blowing will determine what the weather will be like for the day. Wind is occurs when air is heated by the Sun and then rises. Then when the warm air rises cool air moves quickly to where the warm air once was. This is known as a convection current. A type of wind that we are most familiar with are land breezes and sea breezes. Land breezes occur mostly during the night and early morning while the sea breezes occur during the day. Land breezes form when warm air from the sea is released which rises. Then cool air from the land replaces the warm air which causes the land breeze. When sea breezes form the warm air from the land rises which is replaced by cool air from the sea forming a sea breeze.

Interesting facts:
1) The land breeze at night has lower wind speeds because the difference is temperature is smaller between the land and sea at night.
2) Land can absorb heat faster than water.
3) The monsoon known from South-East Asia is really a larger scale of a land breeze and a sea breeze.

Social Studies Blog on Technology

Technology has been an important part in society. Several tools, machines, and appliances have been invented over the course of time. In the past thirty years, I believe that the internet access has had the most impact on our society. The internet has enabled us to be able to research topics quicker and easier. Also today, the internet has let us communicate to others. I believe that the internet has made the most impact on society because it has developed since it has been discovered and become more popular over the years. With this, the internet has many uses besides research and communication.

In science class, we learned the importance of Charles Law. Charles Law states that if the pressure increases then the volume increases. If the pressure decreases then the volume decreases. During the time Charles Law was invented, hot air balloons were very popular. Jacques Charles and Joseph-Louis Gay-Lussac, the creators of Charles Law, were interested in hot air balloons also. An example to show Charles Law is a soda bottle. When the soda bottle is cold, there is very little pressure that comes out of the bottle which doesn't make the soda overflow out of the bottle. When a soda bottle is warm, there is more pressure from the heat which causes the soda to squirt out of the top.

Three interesting facts that I learned are:

1) When the pressure decreases then the volume decreases and when the pressure is halved then the volume is halved.

2) When the temperature of a gas in a closed container is raised, the speed of the molecules of the gas increases.

3) The equipment used by Jacques Charles was very similar to the equipment that Robert Boyle had used to invent Boyles Law.

I believe that without Charles Law we wouldn't understand why the pressure decreases and the volume decreases or why the pressure increases and the volume increases.

Wow! Have you ever seen a pig glow fluorescent green? Well in Beijing, China a Chinese university reported that a pig was cloned whose genes were altered to make it glow. This pig passed down this trait to its offspring. The birth of the glowing piglets shows that transgenic pigs are fertile and able to pass on their offspring. Because of the birth of the pig that glows fluorescent green, this could lead to the future breeding of pigs for human transplant organs.

Interesting Facts:
1) The piglets' mother was born with this trait.
2) The organs from genetically altered pigs would solve some of the conflicts of rejected organs in transplant operations.
3) If the organs from the pigs to humans, then presence of the green protein would allow genetically modified cells to be tracked.

Opinion:
In the future, I believe that using the organs from these pigs will improve the health and lives of the people in generations to come.

Could you ever believe that whales, dolphins and porpoises may have come from a deer-like animal? Scientists have dug up fossils from a creature called Indohyus. The hypothesis by an Ohio anatomy professor predicted that the hippo was the closest land living relative. Indohyus could connect to whales by the positioning and shape of specific molars which are about 50 million years old.

Interesting Facts:

1) The earliest whales looked like a cross between a pig and a dog.

2) The observation of the teeth showed that the creature, Indohyus, spent most of its time in the water.

3) This animal is the "missing link" to the sister species of ancient whales.

The article was extremely interesting because I learned that whales and dolphins have a connection to a land living creature. This creature is predicted to look like an odd raccoon-sized animal that looks like a long-tailed deer without antlers.

Then follow the instructions about adding a page element at omegascience.blogspot.com.

1. My favorite TV show is Gossip Girl because you can relate to it.

2. My favorite meal is pizza because it's yummy. What's not to love?

3. My favorite nonschool activity is hanging out with my friends because they help me forget about the hard things in life.

4. Someone I look up to are my parents because they always head me in the right direction.

5. My goal for the future is succeed in life and have a wonderful job.

6. In the first hour after school I usually do my homework, go on the computer or hang out with my friends.

Newton's Laws

Sir Issac Newton formed three laws using observations of the world around him, called Newton's Laws. His three laws explain rest, constant motion, accelerated motion, and describe how balanced and unbalanced forces act to cause these states of motion. Newton's first law is often termed "Law of Inertia." His first law states if an object is at rest will remain at rest and an object in motion will remain in motion unless external force is applied to it. For example, if you slam suddenly on the brakes of a car, you will jerk forward or move your body forward. If you're not wearing a seatbelt, you could go flying through the windshield! Sir Issac Newton's second law states the relationship between force, mass and acceleration, F = MA or force = mass x acceleration meaning, the force of an object is equal to its mass times its acceleration. For instance, who would have the largest impact, on the bed, if a 265 pound person (M1) and a 128 pound person (M2) both jumped at the same accelertion (A) and landed on the mattress? The 265 pound person would make a larger dent (F1) than the 128 pound person (F2) because 265 pound person is heavier and has more mass, therefore, producing a greater amount of force. Lastly, Newton's third law states for every action there is an equal and opposite reaction. For example, you shoot a gun, the bullet will go forward, but the force that makes the bullet shoot out, causes you to feel a "kick" backward.

Three interesting facts that I learned are:

1) Newton's first law is often termed "Law of Inertia."

2) Sir Issac Newton's laws weren't as famous as they are today.

3) Sir Issac Newton's work is considered to be one of the most important contribution to science.
