       This article is about "Deer-Like Species: Extinct Cervid Species Remains Discovered in Barcelona" http://www.sciencedaily.com/releases/2013/10/131018132056.htm

       Scientist have just discovered remains of an extinct cervid on the Iberian Peninsula. The animal names is Haploidocerod mediterranues lived about 90,000 years ago. This type of cervid are smaller than a normal deer. Researchers used antler's morphology to find what type of animal it was. The Cova el Rinoceronte is a Palaeolithic site of excavation scientist use since 2002, in which they have fund elephants and turtles. Now that they found a new species they know that they can find information of evolution.

       In my opinion this article is credible and interesting. There are many species that have not yet found and this proves that researchers are getting close on finding this species. Gives an idea of different type of animals that have may live throughout evolution. The authors describes the article very well and gives information about the excavation site.

      This article is about "Shark Trackers" by Mara Grunbaum
 http://web.ebscohost.com/ehost/detail?sid=4041b30e-16cc-45b4-b230-19f2c38d2f34%40sessionmgr112&vid=1&hid=117&bdata=JnNpdGU9ZWhvc3QtbGl2ZQ%3d%3d#db=ulh&AN=87349905&anchor=toc

      Scientists have created a small robotic submarine to learn more about predators underwater. One scientist ask "how do you study an animal that lives in the entire pacific ocean?" One technique for this is to mark sharks with acoustic tags under the shark skin in which every second it transmits a "ping" of sound through the water. Scientist are going to use acoustic receivers to listen to the pings to know if the shark is near. The problem was that the receivers had a limited range and the shark was lost. They create self guide submarines to follow the shark were it goes.

  In my opinion this evidence makes this article credible because it explains in much detail how the submarine works and how each device works. There is very little information known about sharks and it is possible that they may be ding other things than just being swimming around the ocean and eating. The technology that we have today it is very easy to built the self guided submarine

     This article is about "The Vikings Were Not the First Colonizers of the Faroe islands" by Durhan University. http://www.sciencedaily.com/releases/2013/08/130820102510.htm

         There is evidence of human activity in the Faroe during at least 300-500 years ago. There was found evidence that other group of people lived there before the vikings got to the Faroes. Archaeologist found burnt peat ash from ancient humans. t is confirmed that there was human activity in the Faroes before the vikings got there, but still it is unknown were this people are form or were they came from. It is believed that Vikings destroy most of the evidence of any other humans when they colonize the islands, and that the humans that lived here stayed for sometime.

         In my opinion this evidence that has been revealed makes it credible to see that there were other humans before the Fareo were colonize. The author does give excellent evidence to this and makes you think if it is real or not. It makes you realize that there are many undiscovered things in the world and that each year something new is discovered. In which makes you believed that there is a chance that there were people in the Faroes before the vikings got there and that they lived their for some time.

       The article is about "Wolves Howl Because They Care: Social Relationship Can Explain Variation in Vocal Production." by Cell Press. 
http://www.sciencedaily.com/releases/2013/08/130822122804.htm

        Animal vocal production may be seen as voluntary. Wolfs can use their vocalizations in a flexible way. Scientist  know little of  why animals do this sounds. On the science center human walk with wolves. They record each of their reaction wolfs have when they take them for a walk.This observations shows that wolves howl more  when another wolf in which has a relationship with the others wolves or is in a high rank leaves the wolf pack. Scientist think that they howl so that they can reunite with the other wolves or to stay in contact with them.

  In my opinion this may be true because animals for example wolfs howl to communicate with each their. So then they can be howling to communicate with other wolfs near the area to form a group to hunt or to just see were are the other wolf packs. The author of this article did gave much of evidence in which it makes it more easier to believe that wolfs are howling for
communication or to find other wolf packs. 

classroom safety

         


         Safety is very important thing in chemistry class because for example using goggles is very important because if there s a chemical that you are working with and it gets in your eye than you can finish being blind. Always use the appropriate equipment in a lab, no horseplay and always wait fr the teachers instructions are basically the most important rules in the class that are needed to follow. Science is a very interesting topic to learn about mostly because you learn things that are useful to know about. In the class of chemistry I like how the teacher explains very well and with energy. In this year I am going to study and pay attention to make it a successful year.
