Welcome to Mr. Ullrich's Blog! This blog is for 8th Grade Earth Science and Physical Science students. We will learn topics such as Astronomy, Geology and Meteorology. This blog will give us a place to discuss, learn and develop these topics during the year. If you are not from our class please post lots of comments!

Pollution is basically... natural or unnatural substances that are put into our atmosphere, oceans and various parts of our earth. When you turn on a car, you just put pollutants in the air. When you throw a soda can on the floor, you put a pollutant on the ground. Finally when you spray cleaning materials, guess what... you just added some more pollution into our air.

There are many ways to stop pollution. One of them is to limit your car use. Walk to school, yes that's right I said walk=http://=http://!!!! Or instaed of having someone drive you to your friends house, ride your bike. Lazy America!

Pollution is always in our lives, it always will be. If your a pro global warming kind of a person, you probally know this already, but pollution is causing our ozone layer to start to dissapear. That's not good. and if your in L.A. you sometimes can't see down the road because of all the smog.The suns rays are melting the polar ice caps and the water level is rising. That's not good either. It's also not good to breathe this stuff in.

I bet you could write a letter to Mr. Obama expressing your feelings twoards pollution. We aren't the only country that is full if pollution. China's air quality is so bad, that O;ympic runners withdrew from the races. That's something I find disguting. After all this happened, China still has all of it's factories running.

Global warming is not real. That's my opinon. I believe in this opinon because we really have to wait for a long time to collect enough data to prove that the earth is getting warmer. If this was 2110, and people had over one hundred years of data that proves that the earth is getting warmer,I might start to believe. People make a good point when they talk about how fossil fuels from factories and cars are aiding the greenhouse affect. But, we've had cars and factories for alonmg time. If the earth's temperature isn't really moving up that drastically, global warming is definately a myth. I couldn't find a video.

The sun is a great form of energy. It is very reliable, and will last for another 5 million years. It creates enough energy in one minute to power the whole world for one year. That means that in a day, it can produce so much energy, that our people can still use it in 27 years. In three days, the sun has produced more energy than all of the fossil fuels. In 1767, Horace de Sassure created the first solar collector, which heated food. The first solar water heater was created by Clarence Kemp in 1891. Ed Becquerel saw that the sun could possibly use the "photovoltiac effect." This is a formula for light and potential energy. This would eventually lead to the discovery of how to convert energy from the sun into usable energy. Will Bailey created another collector made up of a box and copper wire. The first solar cells were created 30 years ago, and we are still making progress. Solar power use is increasing each year by 15 percent. It is very expensive to purchase a solar panel though. These are what converts energy from the sun into regular used energy by P.V. cells absorbing the light and converting it into energy.

My opinion on this article is, that there is maybe another planet like ours but it may not hold life. It's so hard to see if there is water or not ,or if there is oxygen or not. I mean, if we ever had to move, we should try and find one of these planets. Maybe, they can support life. If they can, we could possibly have a whole new planet to live on. How we would get there I'm not sure. But I'm sure we can find away. We got a man on the moon.

A planetoid is a name given to a celestial object that isn't large enough to be considered a planet, but are also too small to be classified as a meteorite. They are thought to consist of debree from our solar system. They are also thought to be the reason why gas giants have so many moons. The closest one to us is pluto. It is 5750.54106 kilometers away from earth. Pluto was discovered in 1930 by Clyde Tombaugh. He discovered pluto from studying pictue panels. I think that planetoids are interesting because it shows how small some things can be in our universe.

I'm Jack. I am in Mr. Urllrich's Earth Science class. I am a crazy football fan. My teams are the New York Giants, and Penn Sate Nittany Lions. I've been a Giants fan forever. I try and watch every game I can. I also play football. I played for the school team. I played linebacker and fullback. I scored three touchdowns and had one sack. Our record was not as bad as last years. I also enjoy playing lacrosse. I play defense. Last year I scored my first goal and am planning on scoring many more this year. In school, I am trying as hard as I can. I am taking Italian and as you may of heard Earth Science. Earth Science is actually pretty interesting. I thought it would be a lot of notes but it's actually a lot of labs.



These are some of the things about me.
