What clown? I was talking with my mom...

Are cellphones too much of a distraction?

      Talking on the phone distracts you from what's going on around you.  This article from the New York Times shows how much people miss when talking on the phone. Researchers at Western Washington decided to do a study on this. They first had to get a distraction to distract pedestrians walking around the city. They chose a very bright, noticeable, and out of the ordinary clown riding around a square in the city on a unicycle. This part was played by a student named Dustin Randall. After the pedestrians crossed the square, the researchers asked them if they saw any thing strange. After they asked the pedestrians if they saw a clown on a unicycle. Here were the results:

The question asked by researcher	People walking with a friend	People talking on phone
Did you see anything unusual?	60% mentioned the clown	8% mentioned the clown
Did you see the unicycling clown?	71% saw clown	25% saw clown

1 in 3 people listening to music or walking alone mentioned the clown.

The conclusion of this experiment shows that more people not talking on a phone, but rather walking with friend see the flashy distraction or clown. And many people in the city are talking on the phone while walking. This is a safety hazard because if there was a fire or dangerous hazard these people wouldn't notice it. Not only is this not safe for pedestrians but also drivers that talk on the phone. If they don't notice what is going on around them then they can get in an accident and risk not only their life but someone else's too. This is why it is important to not be blocked out of events going around us.

            Even though this article does not have much to do with Mr. Hazen's Science class, it relates with everyday lives. Whenever I go in to New York City I always see pedestrians talking on their phone while working to work or for something else. Also everyone has seen someone talk with Bluetooth in their car. Most people use Bluetooth everyday as an average thing in their life. Although they probably never realized how dangerous it can be.  I chose this article in the first place because it is something I can relate to rather than an article with many scientific terms that I don't understand. I find this written piece very interesting. In addition the results are amazing how that many people don't notice a bright and colorful clown.

Is there water on the moon?

     

        On Friday, October 9th NASA launched two spacecrafts to crash into a crater on the moon in search of water.  There were two steps involved in this process. First, the two ton rocket crashed into a dark and cold crater near the moons south pole.  The second spacecraft followed the rocket and tried to collect data that flew up from the debris of the crash to detect if there was water in the moon.  The trailing craft also recorded a video of the explosion.  Although the explosion did not create a huge splash of water NASA was able to collect the data they needed.  Overall, it is not yet definite if the moon contains ice but we are getting closer and closer to the answer everyday.

          This article is very appealing because it's interesting that there could be stuff out there that we would never know about.  I also wonder if life could survive on the moon.  Last year in class we did many things relating to space such as recording the moon phase each day (full, Crescent).

A Dinosaur Footprint?

On October 6, an article was published saying dinosaur footprints that were made about 150 million years ago were discovered in France. The actual discovery was in April by a science society that specials in geology and paleontology. Paleontology is the study of fossils, and geology is the study of a science that deals with history of the earth and life, and is usually discovered in rocks. The footprints are 1.5 to 2 meters wide. The scientists believe they belong to a Sauropod. The most well known sauropod is the diplodocus, which has a long neck and tail, and weighed about 30 to 40 tons. The footprints were discovered during soil erosion when wood unloading operations were taking place. The footprints were made into a mold of calcified mud, and then once that was dried, it was covered with another layer of the mud. The mud has dried now, and it’s an excellent way to preserve the footprint. Scientists want to find more footprints, so they will find out more about why the dinosaurs were in that region. They think they might have been looking for food, but they want more information to make a correct explanation.

This article was interesting because these footprints could lead scientists to discover more evidence about why the dinosaurs were there, and what they were doing. This could enhance our knowledge because with study we would have a better idea of what the dinosaurs were like because they don't exist today, and we can only rely on fossils and evidence from people before our time, so finding information ourselves will make the dinosaurs more clear. I thought this article was very interesting and I can’t wait to find out more about the footprints in future discoveries.

This video on MSNBC that explained the discovery.

Marie Curie

This article was about the life of a French woman of science.

Marie Curie was born in the mid 1800's and had always had an interest in science. When she was 24 she went to the Sorbonne to learn more about her specific interest in radium. Throughout her whole life she experimented with radium which is an almost pure white metal that is extremely radioactive. This means that it is very dangerous and she helped make it possible for people to study the metal and all of its properties. By separating radium particles it would be easy for the scientists to further study this metal.

In 1903 she won the Nobel Prize for physics because of all the work she contributed by looking at radium. In 1911 she actually won another Nobel Prize in chemistry because of her further work having to do with radioactivity. She had her own radioactive safe lab and was known for working in it until the year she died in 1922.

This subject has to do with many things that our class is doing in science. First of all we were talking about the Nobel Prize winner for physics and chemistry and I thought that it was interesting that there was actually a female winner for both of those categories. Another thing I found interesting about this topic is that she did all of her work on a metal which is what we just had a test on and it's on the periodic table. I also think that this topic has to do with the atomic theory because she was working with very radioactive substances and that is what we are about to learn about. Finally radium is an element and this topic just goes to show that elements have so much to do with the real world we live in.

Man who plays with lions

Kevin Richardson is the man who plays with lions in South Africa. As soon as he walked in where the lions were, he was wrestled to the ground. Alarmed, the reporter asked if he was alright. For Kevin that attack was normal.

Kevin Richardson met his first lion when he was 23 and loved it. He met two lion cubs born in captivity and he was allowed to spend time with them. He had no idea that it would change his life. Those two lions are now part of a pride of 38 that have all accepted Kevin as part of their pride. When Kevin roared, the lions all slowly started coming towards him. Then the big males roared back at Kevin. The reporter was scared that Kevin would  get hurt, but instead the lions rolled around him waiting for their stomachs to be rubbed and manes to be stroked. Kevin also became part of the pride without weapons or food treats. They naturally accepted him. Even the lionesses, very protective of their cubs, were relaxed when Kevin played with them. One lioness named Meg is so fond of Kevin that she goes down with him to swim in the river together quite often. Lions do not like the water, but Meg puts her paws on his shoulders and splashes. Kevin's lions are not tame, they still have plenty of wild instincts, so the reporters were not allowed to interact with the lions for their own safety. Kevin knows that even though he is the only human the lions have accepted, that could all change. He is aware that they could kill him very quickly, but if they did and he could come back to life, he would do it all over again.

Possible Signs of Water on the Moon

On Thursday September 17, 2009, pictures from NASA's new moon orbiter, LRO (Lunar Reconnaissance Orbiter), successfully completed the testing and calibrating part of its mission and moved on to mapping the orbit of the moon. The LRO's materials made measurements of space radiation in the lunar environment and found areas of possible signatures of water. The LRO's LEND (Lunar Exploration Neutron Detector) showed shadowed regions that could potentially be the place of water ice and hydrogen. LEND needs a decrease of neutron radiation from the lunar surface to tell whether or not there is water or hydrogen. A big finding from it is that the hydrogen isn't only in one spot, and the team members on this discovery want to know more about it.

This spacecraft launched on June 18, 2009 and should keep working for a year. As of right now it is in good shape. The main goal of this exploration was to find landing spots for astronauts to land in the future, and to make a map of the moons surface, temperature extremes, and radiation environment. Now, it will also be looking for water ice in the permanently shadowed craters of the moon's south pole. If they find water ice, it will be good for the astronauts because they could melt it for water, and they could extract the hydrogen and use it for fuel. However, some of the maps show steep crater slopes that would be difficult for a truck or car to drive over, so that could create a set back for getting the water ice in the craters. On September 9th the LRO will land on the moon's south pole to get debris samples that will be used for future results.

This article is interesting because if there is water found on the moon, it is a huge discovery for future explorations to the moon. If there is water, it could be very useful to the mission and to the astronauts because having water on the moon would mean that the astronauts wouldn't need to bring it with them, so then they would have room for something else that they might need.

Chupacabra caught in South Texas

A rancher in the South Texas town of Cuero reported nearly two months ago that she has caught the legendary chupacabra. Phylisis Canion said the animal had been living near her ranch for years now.The animal would sneak on to her ranch and kill animals in the middle of the night. It snatched cats at first, then chickens through a wired cage.

"[It] opened it reached in pulled the chicken head out, sucked all the blood out, and left the chicken in the cage," she said. Residents believe that the creature responsible is the legendary chupacabra. Its named translated into English means goat-sucker because the creature drinks the blood of livestock.

Canion also says that two other chupacabras have been sited in Cuero. All of them were reported to have blue-grey colored skin, no hair, and strange teeth. Although residents believe that Canion captured a chupacabra, scientists believe otherwise. State Mammalogist John Young believes that Canin merely caught a grey fox suffering from mange. Mange is a virus commonly found in animals that cause hair loss and skin discoloration. "When mange goes untreated it causes this type of reaction. they start to itch, lose all their hair, blue grey coloration. and the animal usually dies from it," he said. Except in this case a car is what killed the creauture. Scientists also took DNA samples in order to see if the creature was really a chupacabra. Until the results are finished, no one will know i the animal was truly the chupacabra
