The word atom is comes from the Greek word atom which means indivisible. The Greeks thought that matter could be broken down into pieces too small to be seen. These particles were called atoms. Atoms are composed of three types of particles: protons, neutrons, and electron. Protons and neutrons are responsible for most of the atomic mass e.g. in a 150 person 149 lbs, 15 oz are protons and neutrons while only 1 oz. is electrons. The mass of an electron is very small (9.108 X 10-28 grams). Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-).The electrons of an atom are bound to the nucleus by an electromagnetic force. Likewise, a group of atoms can remain bound to each other, forming a molecule. An atom containing an equal number of protons and electrons is electrically neutral, otherwise it has a positive or negative charge and is an ion. An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element, and the number of neutrons determines the isotope of the element.
This is some information about Costal Redwoods I dug up. Coast redwoods are truly amazing features. They grow only in California due to glacial activity. A redwood tree is considered an adult when it has lived a millennia! People come from the other side of the world to see them. Coast redwoods do not die of old age. In fact, they may produce 600,000,000 seeds per year! Coast redwoods grow in a narrow strip on the coast of California, 150 miles north of San Francisco. The strip is 500 miles long, and 20 to 50 miles wide, but the conditions have to be perfect for a coast redwood to survive. There needs to be frequent summer fog, and considerable rainfall. Redwoods usually grow with Douglas fir, Tan oak, Madrone, Grand oak, and Bay lourel. However, there can be redwoods that grow by themselves. Some animals that live near redwoods are: raccoons, skunks, elk, deer, squirrels, and birds. No wonder birds live near redwoods, because they are huge.Redwoods grow up to 360 feet tall in good conditions. They can be easily named the tallest tree species on Earth. Redwoods grow so big, because they grow very fast. A 20 year old tree grows 50 feet tall and 8 inches thick! The average size for mature redwood tree is 200-275 feet tall. The biggest trees are 200-275 feet tall. The tallest tree on Earth is named Hyperion and is 370.1 feet tall. However, in order to succeed these massive things need to reproduce.
Raccoons are truly amazing creatures. Here are some facts about them. Raccoons climb very easily, and are not bothered by a drop of 35 to 40 feet. Both captive and wild raccoons have been known to live up to 16 years. However, the species' life expectancy in the wild is only 1.8 to 3.1 years, depending on the local conditions in terms of traffic volume, hunting, and weather severity. It is not unusual for only half of the young born in one year to survive until their first birthday. There are seven species of raccoon, five of which live on tropical islands. Raccoons can swim as fast as 3.0 mph and are able to stay in the water for several hours. The raccoon has short legs compared to its own body, so it is not able to run fast or to jump far. Raccoons are extremely adaptable, being found in many kinds of habitats and easily living near humans. Raccoons are considered the most omnivorous animals on the planet! They are very intelligent. In studies, raccoons were able to open 11 of 13 complex locks in less than 10 tries and had no problems when the locks were rearranged or turned upside down, also they can distinguish boxes containing two or four grapes from those containing three. Raccoons are commonly associated with washing their food. Their Latin name, Lotor, means "the washer." People sometimes keep young raccoons as pets, because they are curious and intelligent. Once grown, however, raccoons can be quite destructive in and around homes. I hope you enjoyed these facts!
As many of you probably already know, Google has made a ney browser called Google Chrome(this post is proudly made using Google Chrome). This browser is better than Safari, Firefox, Operah, and Internet Explorer combined. Firefox users, your browser has so many buttons that I don't know about you but they get me confused! With Chrome, all of the options are stored in a little button that says, surprisingly enough, "Options". Same with settings and bookmarks. Operah users, your browser is so...........well.............boring. I mean the buttons are so ugly! Chrome is new. It has it's own buttons, even it's own theme! I have nothing bad to say about Sarari, exsept that it dosent have tabs. Chrome has tabs so you can open many windows at a time by just clicking on the plus! Internet Explorer users, your browser is so plain and gray! So many confusing buttons and is slow(also depends on your router).

Journey to the Center of the Earth is a great movie and I really recommend it. It may be a little sudden it 3D, so I suggest you see it the old-fashioned way. It has a great plot of science fiction, history, and adventure. The movie is about a man, who's brother disappeared not long ago, for an unknown reason. The man is a scientist who studies what is going on under the world. he has placed many sensors throughout the world that sense the temperature underground. When that temp. exceeds a certain level, they send an alarm to the scientist. When a 4th sensor in Iceland sends an alarm, the scientist goes over there immediately to get the sensor and read its history, but the weather is terrible, so they get trapped in a mountain that leads to the center of the Earth, meanwhile the temp. rises to an extreme height in which they will not be able to survive in. Can they get out before they are boiled alive in their own bodily fluids like the man's brother? Journey to the Center to the Earth is a great movie and I really recommend it.

Look in the mirror. What if the person you see actually existed? Well, he might! Scientists think that in a different universe there is a planet just like ours, in a solar system just like ours, in a galaxy just like ours in, a universe just like ours! Think of it like the universe is looking into a mirror, except the image is real. We want this antimatter because it can produce a ton of energy. Enough to launch a space shuttle 10 times! It could be a completely new source of energy! But we have to be careful, because if one full atom of matter comes intact with it.. Oops! Nuclear explosion! That is what they are doing at C.E.R.N. world's largest study of particle phisics(see blog below). There is a theory that when they get to close to each other, they explode because particles get excited, they generate so much heat, they release so much energy, that they blow up. Like all regular atoms, antimatter atoms have antiprotons, antineutrons, antielectrons, and antinucleuses.
