Candy bars HISTORY
This article is for http://www.candyusa.org/candy/candybars.asp. It does not say who rote it sorry every one.
The article is on the history of chocolate/candy bars. The article says that chocolate was a favorite of Montezuma(emperor of the Aztecs) . bake then it was a drink. Ti tells all about chocolate and how it was a drink up till after 1529. than it tells how we used it in W.W.1.for the soldiers to eat .
This article was so good I love it. It was so interesting. I never knew S.Hershey made his fortune in caramels before he got chocolate in his factory. It says in the 1920’s 40,000 different candy bars were on the spot . WOW that a lot

Weekly Article
I read the article called “How the Brain Turns Reality into Dreams,” by Kathleen Wren. I found this article through google.com, and was interested in it because of a dream I had few nights back. The article was about how the brain takes current memories, and turns them into dreams. It also showed how people with amnesia dream the same way although they may not recall the memory. To prove this they did an experiment using a group of people with amnesia, and people without it, and had them play “Tetris” on the computer at a desk for a couple of hours. When both groups of people woke the next morning, they all reported of falling objects, similar to the game. This implies that dreams come from a memory that you have even if you are an amnesiac, “implicit memory”.
I liked this article much more than the other 5 I have done, because it is the one I am most interested in. The article was good because of all the examples Wren used. I also liked it because it wasn’t too hard for me to understand, and it wasn’t made for 5 year-olds, which made it the perfect reading level for a middle school student. I enjoyed the article because the paragraphs were of medium length, and there weren’t too many ideas going on at the same time. I didn’t like that actual website had many so ads, it got in the way of reading the article. I also didn’t like how it ends, I think there should be a closing statement, but overall I liked this article.

This is regarding RoRoFoSho’s article.
Thats a really cool article Mr. FoSho. The article really tells me that your brain is still processing information, even if you have a mental condition that is suppose to impare your ability to remember things, but this article shows how you still have that info somewhere in your head. Very nice.

Article Name: “First Invisibility Cloak Tested Successfully, Scientists Say”
Author: Sean Markey
Where it can be found: http://news.nationalgeographic.com/news/2006/10/061019-invisible-cloak.html
This article is about how a team of scientists successfully tested the first invisibility cloak. This is a significant breakthrough in science, even though the cloak only works in two dimensions and only on microwaves. To make the cloak work, they needed to wrap electromagnetic waves around the object and make them connect on the other side. David Schurig (physicist on the team) said, “You can think of it visually as like water flowing around a rock smoothly.” To make the electromagnetic waves do that, they used metamaterials, which are a matrix of tiny metal wires and loops used to control electromagnetic radiation, in ways that natural substances can’t. Even though the scientists made a big breakthrough, they still have a long way to go. The object that they cloaked was only 5 inches wide and 0.4 inches tall.
I really enjoyed reading this article. It was interesting and cool. I remember when I first heard about the invisibility cloak, around the end of last May, and I remember thinking that it would take forever for them to make it work on anything. But they made it work, in less than half a year. Even though the object they cloaked was tiny, their accomplishment wasn’t. It’s flabbergasting to think that they were able to come so far in such a short time. Before this, the only invisibility cloak we knew was the one in Harry Potter. Now it is a reality. I also find it really cool how they developed something that can manipulate electromagnetic radiation. I wonder how it works.
Even though the scientists haven’t been able to successfully cloak a 3-D object yet, I predict that they will be able to do it soon. I look forward to it and I’m sure the rest of the world does too. It’s a remarkable stride in technology and I hope they continue to better the cloak.

That is a very intresting article. I think it is weird how choclate was first a drink. What does that mean? Was it like hot choclate, or was it more of a drink on it’s own? S. Hereshey, thats the inventor of Hershey choclate, right?

The article I read was “Oldest Writing in the New World” written by Eric Jaffe. I found it at http://www.sciencenewsforkids.org/articles/20060920/Note2.asp
The article was about a stone slab found by road builders in Southern Mexico a few years ago that is covered with marks. The area where the stone was found was at the center of the ancient Olmec civilization. The writing shows an early form of Olmec writing from about three thousand years ago.
I think the author could’ve done a better job supporting his main idea. He said, “The signs on the stone, for example, appear to run horizontally, whereas later writing in the region ran vertically,” but how do they know that they weren’t holding the stone sideways? He said the stone “displays an early form of Olmec writing, dating back nearly 3,000 years” and that “scientists previously found samples of Olmec writing from 2,650 years ago” but it doesn’t say how they can tell the difference between the stones that are 3,000 years old and 2,650 years old. I think, by adding just those few things the article would be a lot better, but overall it was a very interesting article.

Weekly Science Article
http://www.smh.com.au/articles/2003/01/17/1042520761702.html is the location of my article.
Retell: This is an article about a small yacht that was taking part in a sail-around-the-world competition, that was attacked by a Giant Squid. The crew felt heavy vibrations coming from the bottom of the boat. The crewman who was sent down to investigate found a large tentacle gripping the underside of the boat. The crew brought the boat around, and when they brought it to a complete stop, the tentacles released their grip. The creature was enormous, with tentacles thicker then a full-grown man’s arm.
Response: This is a really amazing thing to have happened so recently, (only three years ago) the crew was very lucky in my opinion, because the Giant Squid released them when they brought the boat to a complete stop. I think that the Giant Squid was attacking them because it thought that their boat was a Sperm Whale, the Giant Squid’s biggest enemy, which the Giant Squid will usually fight with near the surface, then drag down to the depths to drown it. I think, that if the crew was close to shore, they should have abandon ship, because their small figures would not look like a Sperm Whale to the Squid. But their course of actions allowed them to survive.

Weekly Science Report
The article I read was called Internet Generation, by Emily Sohn. I found it on http://www.sciencenewsforkids.org.It was about how adults are noticing the the pro’s and con’s of the internet. Scientist were takeing surveys to learn what kids know about the internet. Most younger kids thought that use the internet said that they thought it was an icon and was just programed into the computer. They also think that the internet sometimes shows folew photes and words. It could also give the wrong info if you were on a fake site. Parents also see that kids are partisipating in things on the internet and working together. They also think that the internet can give kids “power.”
I think that this article could have done better reaseach and actully asked kids what they do on the internet. I do agree with them though that tecnolagie is a big part of this centrey and that some peaple take advantige of it. I find the amount of students useing the computer every day not a big surprise {90 percent} Befor I read this article like most kids I thought the internet was simple but it said that “the Internet is one of the most complicated entities in the universe.”

Fish Fossil Find by Claudia Atticot
The article I read is about a fish fossil that was found last week. Aparently this type of fish only lived 380million years ago. It is the only fish that actually has teeth from its time. I got this article from http://www.timeforkids.com.
I think it’s pretty cool that they found a FULL skeleton or close to one of a fish that is from millions of years ago. I never knew that fish could have teeth and since they used to, why don’t they have them now? This article is very interesting but I think it is to short, it needs to have a little more information. I would actually want to read more about it.

INVISABILITY CLOAK
On Thursday October 19 2006, the worlds first working invisibility cloak was tested at duke university. An invisibility cloak is not a magic cloak that can turn you invisible. It is a mesh of of “metamaterial”, a bunch of electromagnetic conducting material organized in circles. The concept behind an invisibility device is relitovly simple: a mesh of material that stops light from bouncing off of it. If the light can’t return to the eye, the eye can’t see the object. Duke made a five square inch piece of metamaterial that was composed of copper shapes patterened on to a fiberglass composite. When researchers tested the cloak by aiming a micromave beam at it, they found that the beam flows over its profile like liquid. The cloak worked! Scientists think that it could have many other applications, amuong them military uses, wildlife blinds and also use them to streamline microprosessors.
I think that the authers of this study really knew what they were doing. I think that because the two page article was filled with facts and had a extreamly detailed list of what they did, and they way they wrote it, it was obvious that they knew what they were doing.

Who Built Stonehenge?
By Stuart Carter
http://www.firstscience.com/SITE/ARTICLES/stonehenge.asp
This story shows that about 4,000 years ago the boscobme bowman built stonehenge. The 44 ton rocks show that the bowman had more technology than we expected. This large “ceromonial” stones showed more than we expected. In April 2003 In a boscombe town a grave reaveled bones and framents witch helped the scientists figure more about this large structures.
This story influeced me in many different ways I never knew that 4000 year old people can find a way to lift large stones on top of 2 others. These stones show symbolism and representation in past villages.
I hear about stonehenge in articals but I never knew that this structure was so representitive.

Science Article
Crocodile Heart by C. Gramling.
It is about a crocodiles heart. The heart is a mussel.
What I don’t like about the article is that it is boring. It needs more fun. It is too long that is why it is boring. It needs more pictures.
What I like about this article is that it has a lot of facts. It has a nice diagram of the crocodile. It has a good picture of the crocodile that is up close. The heart in the crocodile is the same as a human.
Overall It was a good article. And it was well written.

The article I picked is called, “The Science Fair Circuit,” by Emily Sohn. It can be found at http://www.sciencenewsforkids.com/articles/20061018/Feature1.asp.
The article is about science fairs and how kids love them so much because they have a chance to meet new people who share their love for science. In the article, Emily Sohn also says that 40 of the top middle school science fair winners get to compete every year in the Discovery Channel Young Scientist Challenge (DCYSC).
I like this article because I think it is interesting in a way. I like how such a large group of kids got to meet each other because of their passion for science. I like the idea of meeting people who share the same hobbies as me, and competing against them doing that same hobby. For example, I love to play volleyball. I would definitely enjoy meeting a big group of people who also loved to play volleyball and then playing against them for prizes. I am very competitive and I love to meet new people, so I would jump at any idea that includes both meeting people and competing against them.

This article is about your sense of smell. It was talking about how we don’t really think about it but some animals such as dogs rely on it more. It said that a dogs sense of smell is a million times stronger than ours. The way we smell is our nose reads molocules.
What I thought was cool about this article is the part about a dogs sense of smell being a million times stronger than ours. I knew that a dogs sense of smell was strong but not that strong. No wonder my dog doesn’t get scared of me when I put on a Halloween mask; she can smell that its me.

Article: Update: Chemical Companies Plan to Poison 5,000 Animals
By: Anonomys
Found: Peta.org
In 2002, chemical coalition companies such as the HPV chemical- testing program. A large amount of chemicals used to produce plastic and adhesive. The original test plan was dangerous enough but the 12 separate new plans are estimated to kill 5,000 animals.
These tests consist of:
-LD50 Test
This test has animals fed large doses of chemicals until they die. These chemicals give off symptoms to their patients such as diarrhea, nose bleeds, as well as bleeding of the mouth and genitals. Before the animals ultimately die they are faced with large convulsions and seizures. The surprising thing about what these companies have to say is that even though these tests are proven to be dangerous and unnecessary by existing data they are proposing 4 other tests.
-Genotoxicity Test
These tests are also harmful. Genetic toxicity tests are mostly preformed on mice. This test involves intubation or shots into the mouse’s stomach. These tests are called In Vivo Genotoxicity Tests. There is a non animal alternative to study genotoxicity that has been accepted by the government, yet the old test on mice is still in 4 test plans.
-Fish Acute Toxicity Test
These are similar to LD50 tests only poison is pumped into the tanks of fish and the fish’s behavioral normalities are altered extremely. The poison puts the fish through pain and also poisons them to death.
Response: I think that this article is telling us to take action on what large businesses are doing to animals. This should be stopped. We wouldn’t let these tests happen to humans. I don’t believe that we should just sit by and watch. I liked the fact that the author pointed out how dangerous these tests are and tell about the chemicals these corporations use. If we let these companies keep doing these tests more animals will perish unfairly.

Storing Memories Before Bedtime
In this article, researchers thought that sleep was a time for the brain to process what it learn that
day but according to a new study the brain begings to process those memories long before you sleep.
To prove their point researchers did a test on 15 volunteers brains right before and after the tasks. They compaired two images to see whether the areas of the brain involved in learning tasks were still active even after the task was completed. After an hour the discovered that the brain stayed active and continues to process new information. Some scientists say that sleep isnt for storing memories, others disagree, but untill its proved they say we should still get plenty of sleep.

How to Silence a Cricket
Only male crickets chirp. They have special parts on their wings that, when scraped against each other, make a noise. In the 1990s, a certain type of fly
began hunting Polynesian field crickets found on Kauai, Hawaii, says researcher. These flies implant their babies in the bodies of crickets. The flies use
the crickets as food, and the crickets eventually die. Because male crickets make so much noise, they’re easy to locate and suffer the most.
Within 5 years, the male crickets stopped chirping almost entirely. By 2003, the cricket population had started increasing again, but only a few
of the males had wings with chirping parts that still worked. A gene or two changed over time, so that the cricket wing couldn’t chirp anymore.
On Kauai, faced with deadly flies that could zero in on the sound, and passed the gene changes on to their kids. Now, these silent crickets are the main
type of cricket on the island. Unfortunately for male crickets, their only way of attracting females is by chirping. For now, the silent males cluster around the
few remaining chirpers in order to meet female crickets.

I found this article at, http://www.firstscience.com/site/articles/time_travel.asp
This article is about how time travel might be possible. I think that this article is a good way to get to know if we actually can travel through time. It would be cool if we could, but it is unlikely that we will be able to anytime soon.I feel that if we can find out how to travel through time, it should be kept a secret because of the amount of traveling people would be doing which could cause a new timeline
