Right now at this vary moment garbage is floating in our space that surrounds are Earth is causing danger to satellites,& other stuff up there is a ring of trash around us right now and it is hurting our Earth and we need to help it. You just can't sit there and not feel sorry for our Earth. You kinda have to because you helped them destroy our Earth. Did you know that over 100,000 tool bags trying to fix the international space station, we are losing the battle here, like shoot lasers at litter, except gravity would pull it back to us. Just start by doing the little things in life, like recycle and stop polluting the water we eat & drink from. Every bit counts.

Right now as I am typing there is space garbage floating around causing satellites & astronauts danger. Rockets, broken satellites, astronauts' gloves, and other junk is polluting space. There is a ring of space trash surrounding Earth. Sometimes, junk falls from outer space into Earth and, one time it hit someone. Once, part of a Russian rocket fell back to Earth. Scientists are thinking of fixing this problem.

One idea is to shoot lasers at litter. Except, gravity would pull it back. Another idea is that space garbage trucks would have a net, catch the garbage in the net, then dump it in Earth's atmosphere. But it will burn up before it reaches the ground. We are still finding a way to get rid of this pollution.

Even today there is more than 300,000 pieces of litter cluttering space! Some interesting facts is that astronaut, Edward White, lost his glove in space and it sped around Earth at 28 thousand kilometers per hour before burning up! Also, the 1958 Vanguard 1 satellite is still orbiting Earth as the oldest piece of space junk. I think we need to be a bit more careful.

I read three articles on space junk and they all talk about different things. I read all National Geographic articles one was on cleaning it up the other were almost the same. The thing is that two of the three both talked about Edward White losing his glove.but the clean up one talked about how they track trash 4 cm in diameter and bigger and now that realized another one also mentioned that. but there saying to send up a ship with a jaw and eat the trash and shoot it into our atmosphere and let it burn. I also think that is a good idea. But all I now is that we got to clean it up before it becomes a big problem and it is also dangorus if there is a colistion between two space junk item.

I read an article about space junk. Actually 2 articles.

The first 1 was the space junk clean up 1 and it told me about how space junk is bad. It's bad because it's just going to continue to grow. The article also said that after 2055 the space junk will increase.

The second 1 told me about how much space junk there is. The oldest known space junk is the Vangaurd 1. It was in space from 1958. That's a long time. Both of the articles said space junk is a problem.

There are a lot of junk just floating around space. Broken satellites, destroyed rocket bodies, human waste, and a glove that was left behind by astronaut ED White during his spacewalk in 1965. I think that it is cool how many random things are floating around space. But I wonder how all that trash got in space. Did it fall out of a satellite or something? Did it float away from someone? Maybe you can help me by answering those questions if you know the answers!

On March 12,2009 the space station had been threatened by a piece of space junk that had been traveling at about 17,500 miles per hour.

Today I read two articles about space junk. Lemme tell ya: It's reeeeeally hard to rid of. Space junk mostly is created when rockets blow up, or when an existing piece of junk crashes into a fully-functional sattelite, thus smashing into a zillion pieces. Computers back on Earth can track where most of this trash is. But only the clutter that is larger that, say, the size of a grapefruit. The other ka-jillion pieces...well.... we can only hope they won't hurt any astronauts.

On average, one piece of space junk falls from space into Earth's atmosphere per-day. One time, a piece even hit a person on the head, but she was not harmed.

Space junk can consist of anything! From gloves, to tool bags, to chips of paint! And the small things, like chips of paint and just tiny pieces of metal, believe it or not, can be the more life threatening.

When some astronauts are in a rocket, and a piece (miniature) of metal comes flying their way, it could tear a colassal hole right in the rocket, costing the astronauts their lives.

Space junk is piles and piles of trash that is spread all across space and Earth. Scientist say that the space junk in space is posing a threat to space activities. They also say that they is becoming necessary to remove some of the space junk. National Geographic says: "Since the launch of the Soviet Union's Sputnik I satellite in 1957, humans have been generating space junk."
I think that space junk is cool but if it's posing a threat to space activities, then they should try to remove some of it. To learn more about this subject go to http://news.nationalgeographic.com/news/2006/01/0119_060119_space_junk.html!

What is space junk and where does it come from, you ask. Well I'll tell you. Have you heard of about astronauts losing camera lenses in space? Well that lense becomes space junk.

All countries should try to help clean up the space, not just us. Scientists are trying to help but its a big job. Space junk can be dangerous too. For instance on March 12, 2009 a small piece of space junk was headed for our space station. They told astronauts to leave the station because that small piece of junk was going 17,000 miles an hour.

Luckily the space station was not harmed. But lots of little pieces make their way though our atmosphere. Once, it hit a women walking down her street. She wasn't harmed, but that's rather scary. I think if we don't get our space cleaned up soon then people will really start getting hurt. Don't you?

I read 2 articles about Space Junk. I hope we can stop it from increasing. The first article I read was about cleaning up the space junk. I liked what they thought would help astronauts. My second article was the big problem the space junk is causing. I thought it was good.

Don't you hate space Junk? I do. Let's get rid of it. The cleaning up article won in my opinion.

today I read a story about space junk. It was a interesting article. The article said that there are more than 2,800 pieces of junk in the earth's gravity. The space station would test their new weapons on the old satellites. China also does this.

I read another article online that say that there is 13,000 pieces of space junk in earth's gravity. That's a lot of junk. The oldest piece of space junk is the 1958 Vanguard 1 research satellite, which stopped all functions in 1964.

These two sites each didn't have the same information. Like one said 2,800 an the other says 13,000 pieces of space junk. so one is off like 10,200 pieces of space junk or they are both wrong an it's more or less. That is a lot.

I just finished reading an article "Space Junk." It told me that in space, there is space junk because of all the rocket stages, parts from blown up satellites, human waste, and human made space junk. They want to remove the junk so they don't hit satellites and ruin them.

One of the articles said that there was 2,000 pieces of space junk. My "National Geographic" book says that there are now 300,000 pieces of space junk traveling the earth's atmosphere. The other article said that there was 13,000 pieces, including Edward White's space glove from when he lost it in his moon walk in '65. It said that his glove went around the earth at least 28,000 times until it blew up. There are also 2,500 satellites working and non-working in space.

Vanguard 1 is still in orbit and is the oldest piece of satellite space trash. A 100,000 tool bag was found in space and you could see it from a telescope. The scientists want to shoot space junk with lasers so then they could move the litter from the satellites, but if they do shoot it away it would come right back because of the Earth's orbit.

The satellites show that Greenland's ice is melting and that if it does than a lot of places around the world will be gone. It also shows some other things, too, that is really bad. like the change in the temperature or the change in the fossil fuel gathered each year.

http://climate.nasa.gov/ClimateTimeMachine/climateTimeMachine.cfm that is the website to see the changes on Earth.

My class is building rockets and I think it's super fun. My rocket is yellow.

The fins have smiley faces and an orange design.

Also, I named my rocket "Mr. Happy."

My rocket is made of math papers, cardboard, and a couple other special things. My rocket also has a parachute so it doesn't break when it lands.

I can't wait to launch my rocket!

I read about the parts of the Rover. On the Rover are the alpha particle X-ray spectrometer, the hazard avoidance cameras, the high and low gain antennas, the microscopic imager, miniature thermal emission spectrometer, the moessbauer spectrometer, the navigation cameras, the panoramic cameras, rock abrasion tool, rocker-bogie mobility system, and the solar arrays. Those are all the stuff on a rover.

This is the link to the stuff about the rover

I just was on the web site http://www.nasa.gov/mission_pages/juno/main/index.html. It tell about how they are sending a spacecraft to Jupiter, but it won't leave Earth till next year, Aug. 2011. It's going to take Juno five years to get there in 2016. And they say it's going to go around 32 times then land on it and stay for a year. Then NASA will say the Juno mission was a success. And I can't wait to see if the Juno will be complete disaster or a wonderful new discovery that we never knew.

Today at school, I was looking on a NASA Website because that is the subject in which we are learning. I started to scroll down the Images page, and at the end was a link to the Picture of the Day. Once I found this, I fell in love! For one, I adore the stars, galaxies, moons, and just looking at pictures of space itself. (When I was on a cruise, every night I would go to the top deck and stare at the stars forever.) This site, I thought, can-and will- give me fascination, entertainment and amazement for hours upon days upon....forever! I absolutely 100% think you should take a peek and the pics. P.S. I recommend April 19, 2010's picture.

About 3 weeks ago our class started making rockets. I was really excited because I always wanted to learn about how things fly! When Mr. Noon gave us the packet with all the stuff that we would need to make the rocket I thought that it would be really confusing, but it turned out to be actually really easy. He also told us that we would need to know everything in the manual because once we were done with this project we would be given a test.

The first thing we did was take out a small plastic tube, which would be used to help us build our rocket and it was going to be really helpful when it was time to paint our rocket so we would not have to touch wet paint! Next that we each got a full piece of typing paper and with that we warped around the plastic tube. Then we toke a half sheet of white paper and warped that around the first sheet of white paper. After that it was time to put the gummed tape on which would be the outside of the rocket, first we cut a 45 degree angle at the end of the gummed tape, then we toke a damp sponge and made the back of it wet so it would stick, last we toke the gummed tape and rolled onto over the paper.

Next it was the best part of the whole project.... getting to design my fin and my rocket!

After I was done making the rocket body it was time to make my parachute that would fall out of the rocket when it comes back down to the ground after I had launch it. When we had gotten the packet there was already a parachute in there all we had to do was cut it out and attach the string. After I had did that I had to tie it to the the screw eye which is a little notch that is screwed into the the nose cone! I had to poke holes in each corner of the parachute an tided a 14 inch long string to each one. After that I took all the strings and tied them onto the screw eye, last I took my parachute and stuffed it into the rocket. Another thing that will go inside my rocket is the shock cord, and that is to keep the nose cone attached to the rocket. And all I did to make that was take a small paper rectangle shaped piece of paper and glued the and of the piece of paper to the end of the shock cord.

I had to poke holes in each corner of the parachute an tided a 14 inch long string to each one. After that I took all the strings and tied them onto the screw eye. After that I stuffed the parachute into the rocket and attached the nose cone onto the top of the rocket.

After my rocket was made and my parachute was done it was time to paint my rocket . This was my favorite part of making the rocket because i love art :). My rocket has white and light pink stripes. And my fins are neon yellow and purple stripes! After my rocket and fins were painted it was time to attach my find to the rocket. This was kinda hard because the fins had to be spaced evenly. Mine ended up not be spaced evenly. But it was not that bad, it might not fly straight though. The last step that was probably the hardest was assembling the engine, and what you would do was have a small card board tube, two card board rings things and a small metal piece that would hold onto the engine. First you would glue the metal piece onto the card board tube then put one of the card board rings on one end of the tube and one on the other end . After you are done assembling the rocket engine you put it into the back end of the rocket and when you are ready to put in the engine that is what you will use! Those are all the steps I used to make my rocket! :)

When testing was finally over, we started to build rockets. The rockets come from a set called Pitsco Rockets. It's for science so I had to make it perfect. The rockets were hard to make because you couldn't mess up. If you messed up then you wouldn't be able to fix it. In this Pitsco set, there is no spare parts. So if you mess up, you mess up!

We also had to take a review test for our rockets. We had to answer questions about what we did, and the history, and discribe what our rockets look like. I think that the hardest part of when we were making the rockets was when we had to make the engine holder, put on the launch lug, and put on the gummed paper.

My rocket looks like a lollipop or a candy cane. It is pink and yellow and it swirls all the way to the top. The nose cone is yellow, and the fins have blue, yellow, and purple on them. It also has my name on it with a little bit tilting to it. I think that it looks like its going to blow up. But maybe not!

In our class we are making Pitsco Rockets from a rocket kit but not one of those lame straw rockets. I mean like real rockets like with a nose cone, and engine. One that you light and it shoots up in to the air. I was the first person done so a lot of kids asked for help. Making the engine holder was the hardest part of the rocket. You took a little tube and a long metal stick type thing and two little rings 1/8 of an inch up you put a line of glue. Then one the other side you put a line of glue an inch up. Then you lay the metal on it and slide the rings over the metal to where you placed the glue.

I find it rather sad that I know all that from memory. Don't you? But it was so fun painting and making the frame for the rocket.

This what the rockets look like before they're painted.

In class we are making Pitsco Rockets. They are ran by batteries, they are kinda small not the size of a real rocket, but that would be cool if we could build a real sized rocket with rocket scientist.

My rocket is orange with black spots, my fins are orange an have a giraffe on one side an on the other it says Giraffe Girl. It says Giraffe Girl because I love Giraffes they are awesome an orange (which is my favorite color it is so spatacular). My rocket is very out going it has it's own personality, and my rocket is the most exciting, awesome an spatacular rocket ever made.(shhhh don't tell anyone it's our little secret.)

Have you ever made a rocket in your life? It is really fun. Have you ever been to a place where they show model rockets? I have; it is really fun but kinda boring.

I like the part when we got to paint the rockets. I think that the hardest part was when we had to make the engine it was very hard to make. You have to measure out 1 inch an on the other side 1/8 inch. that was the hardest part of the project. That was a fun project.

I learned people are going to Jupiter. It will take like 5 years to get there and 1 year to orbit the planet 32 times. I thought that was amazing because Jupiter is far away and it is large. It was on the Constellation site. They're doing it because they want to find out how Jupiter was formed.

I bet they're tired of going to the moon.

You know what? I'm not going to be an astronaut when I grow up. Too dangerous. An Astronaut has to survive dangerous things. Which I'm too scared to do. Why? This is why. You could get killed, machines could not work right, and You are in space where no one can see you. Except your partners. I hate space.

The conclusion is if you try to make me an astronaut it's not going to work because I've listed the reasons why I don't want to be an astronaut.

April 15, 2010 people started calling 911 about spotting a light traveling west to east. There are other people that said there is a fireball that is coming out of the sky!! Scientists are hoping that the fireball survived. When the fireball landed on earth it released 20 tons of TNT. That is a lot of explosives. They had to evacuate the city or town it was nearby. This is a pretty cool story, if you want more information you can click this http://www.jpl.nasa.gov/mobile/news/index.cfm?release=2010-130.

A day in the life of a Strawberry Dart frog would be very tiring for sure, especially for the mother frog. The mother frog has a lot of hopping around to do when her eggs hatch.

Hello there I am a Strawberry Dart frog. Yesterday I laid my eggs in the dirt right around the lake. You know how most frogs lay there eggs in the water well that's not me at all. I lay my eggs on the dry ground or dirt. Then when my little tadpoles hatch I have to get them into a wet place so they will live. One by one they wriggle onto my back then I carry each one safety up into there own little spots in the trees. Then I go back down and get some more an do the same. I have a very "fantastic memory, because I can find each tadpoles and lay a special kind on egg in it's pool so it can have food." That's what I do in a day.

So a day in the life of that frog is very hard. She goes up on land a lot and she also has to be a good climber so that she can climb up those trees with up to 20 tadpoles on her back. Well now you know that she is very tired after a days work to because of all the things she does. This mother is one of the busiest of them all. "Oh yeah and a snake might find one or two of these hidden frogs but chances are they won't find all of them."

The place where fire Rages and Ice shudders.

The land of burning fire and freezing ice (The good side of Iceland)

Do you hear the name of Iceland and think of ice? Everyone does, and they are all wrong. The toughest choice to consider why I say this is go to Iceland, but I got a simpler solution; listen to me. It does have ice (duh, with a name of Iceland of course it does) Here is the tough answer, it has fire too, not just in houses, but in the natural world, too.

Iceland has volcanoes (the fire), ice (the ice), icebergs, mountains, hot tubs.

Here is the report. Come visit Iceland it has red, white, and blue the true American colors (or colours). Red is for the stripes and fire. White is for the stripes and icebergs and icecaps (also ice). Finally blue. Blue is for the water and the place surrounding the white stars. The most exotic thing (my opinion) is the northern lights. A little sprinkle of green wavy lines.

Visit Iceland land of true colors ASAP!!

I am a Brazilian gold frog and I am the smallest frog in the world. I am known to be smaller than a dime! I enjoy being tiny because I'm good at hiding in very small places.

Being tiny is very hard, but it can be fun at times. I like to play hide and seek with my friends. Most of my friends are bigger than me, so it takes then a while to find me. I like to find my friends but I find then real easily. I like going to the lake and having a nap on a Lily Pad. I also like going for a long swim. It relaxes me!

That's what my life would be like if I was the tiniest frog in the world. Tinier then a dime!

I am a Golden Poison Dart frog, but some people call me the Terribilis frog. My name comes from the word terrible because I'm one of the most poisonous animals alive. People that don't know who I am will probably think that I'm a cute little frog because I'm about as big as a quarter.

Just so everyone knows, I'm yellow, but my eyes are black and a little around my mouth is black too. I live in the rain forest and I think you all know why, but if you don't, I will tell you. I live in the rain forest because it is nice and wet and I LOVE water.

If you ever go to the rain forest an see me just remember... don't touch me.

I read a story in National Geographic about Iceland. Iceland would NOT be a good choice for a vacation. It is very dangerous. It wouldn't be good because there are tons of volcaneos and glaciers.

The reason for volcanoes is that they could erupt when you are standing near them and they could kill you. You're dead... What a great vacation! The reason the glaciers would be bad is that if you decide to take a hike on them, you could fall in a crevasse and also die. Two ways of dying in Iceland. That's why I would prefer going to Hawaii.

The land of Iceland is very pretty, but it's also very dangerous. I might not be like whoever is reading this, but I would recommend NOT going to Iceland if you had a choice.

Today the class watched a video called Time Warp Trio and My Big Fat Greek Olympics for social studies, and we had to take notes. The notes were based on fact or fiction. One of the notes that I got is if you fall in a fighting match you are either out or killed. And I learned that women were not allowed to compete in the Olympics and if they did they were killed. I also learned that Plato was one of Socrates' students who became a great philosopher like Socrates. This is weird; the kids in the movie traveled with a book. In the movie one of the games in the Olympics is throwing a heavy disc and a nether is wrestling and that is when the rule if you fall you are out or killed comes in. But I think that rule is dumb so I think they should get rid of it.
