Current Events 3
This year, there were many new different animal species, and some of them were extremely strange. One of them was a monkey that sneezed in the rain (Rhinopithecus Strykeri) and a .02 inch worm that lives about 1 mile under the ground (Devils Worm). The International Institude for Species Exploration at Arizona State University made this list. Coincidentally, this was the same date as the birthday of Carolus Linnaeus, who made the modern system for naming and classifying living things. This list was intended to honor the explorers and museum scientists who found and classified these animals. New monkey species (Below)
Other animals listed was a mushroom that resembled a sea sponge, named after Spongebob Squarepants, officialy called Spongiforma Squarepantsii. A beautiful jellyfish that hides a deadly sting and is the only jellyfish with vision called Tamoya Ohboya. A bead found living with the Devils Worm. A parastitic wasp/ant that attacks other ants. A centipede that is now considered the worlds largest species of centipede called Crurifarcimen Vagans. A new milllipede, and a walking cactus.
I believe that this was an interesting article, and that I learned a lot from this. I really enjoyed talking about this article because I love animals and enjoy watching them. It is amazing to see what our world really is like and how many more wonders and mysteries there are in this world. The world is an endless adventure. Thank you, and bye.

Trapdoor Spider(Left)
Devin Yang.
THE EPIC NEW SPIDER!!!!!!!!!!!!!
In the backyards of Auburn, Alabama, scientists have discovered a new species of spider.
It is a species of trapdoor spider, which looks like taratulas but with a smoother stomach and lives inside burrows. It is called the Auburn Tiger Trapdoor Spider, or Myrmekiaphila. The burrows contain a hinge door, which not only protects the burrows, but also allows the spider to feel the vibrations of other insects and attack them.
A trapdoor spider's burrow. Before, scientists thought that it was a M. foliata trapdoor spider. However, there was a difference in the males genetia and the males copulatory device, which is often used to distiguish the difference between spiders. Using genetic analysis, they confirmed that the spiders were different species. The male spiders are just a few centimenters long, with the female spiders just a few centimeters longer. Female spiders live longer than male spiders, ranging from 15 to 20 years. This is my current events about the new trapdoor spider discovery.

| A raindrop... but this ones not from 2.7 billion years ago!! |
Boyle, Rebecca. "Popsci.com." .Nature. 03/26/2012. Web. 29 March 2012.
The Raindrop..... From 2.7 Billion Years Ago!!!!
In Africa, a raindrop fell. Seems normal right? What is scientists found the remains of a 2.7 billion year old raindrop. Impressive. The raindrop fell in South Africa while the Earth was still growing. The weird thing: 2.7 billion years ago the earth should have been dimmer than it is now. However, this supports that the Earth either had greenhouse gasses or a different atmospheric pressure. In current times, fat rain would fall 30 feet a second. Before, if the rain had a thicker atmospheric pressure, it would have fallen slower, resulting in asmaller mark in the earth.
I believe that the discovery of the raindrop is a huge way of understanding how the Earth was like 2.7 billion years ago. One reason is because humans don't show prior, necessary knowledge on how the Earth was like before our time. The second reason is because this might help us discover if life could be on other planets as well. The final reason is because this might affect later like. Who knows? If the atmosphere changes drastically again, we might need to know what to expect from Mother Nature. All in all, I believe this discovery has impacted human understanding and will help us understand about the past and the future. I have enjoyed reading this article and I believe this will help for later times.

The Ruining of Sugar
States of Matter: Part 2
Materials used: Sugar
Beaker
Buntzen Burner
Cup with Water
In school we performed a lab relating to sugar. First we got a sugar cube and licked it. It tasted sweet. We were also supposed to observe it. It was hard, white and cubicle, unlike the marshmallow. Then we had to crush it and dissolve it into the water. It tasted like tea.
Our next lab involving sugar was to burn it. We observed it and crushed it, just like the previous one. However, this time we burnt it over the Buntzen Burner. It turned black, just like the picture. After it cooled down, our teacher, Mrs. Rousseau, had to break the beaker to get the sugar out. It was black, hard and sort of like a crystal now. Next we were instructed to taste it. It tasted bitter and disgusting, just like the burnt marshmallow, except worse.
As we burnt the sugar, only one item was left...... carbon. The carbon caused the bitter taste. That was a chemical change. The purpose of this lab was to observe a chemical change and physical change, and to show the difference between them. We were also supposed to seperate a mixture. This lab showed how chemical change can affect an original item. That is why we experimented with this lab.

States of matter
Part 1: MarshmallowMaterials used: Buntzen Burner
Small Marshmallow
Large Marshmallow
In class we observed different states of matter by burning a marshmallow. First however, we were given a small marshmallow. We had to observe it first. I concluded that it was small, white, and soft. Then we were instructed to taste it, which in my opinion, I enjoyed. I wrote that it was sweet and soft. Then, we received a large marshmallow, observing it as well. It was big, soft and white. Next, we had to burn the large marshmallow over the buntzen burner. We were instructed to eat the burnt part first. In my opinion, it was bitter and impossible to bear. However, the inside was heaven.
The reason we experimented this was so we could tell the difference between chemical and physical change. We were also supposed to observe the marshmallows change in matter. If I had kept on melting the marshmallow, it would have changed from solid to liquid. I believe we were supposed to realize that even though it was a minor part of this experiment. Due to this, I conclude that this lab was to help us observe matter and physical and chemical change. Possibly to relieve our appetite and help us remember also :)

The 7 items
Just to tell you, my group did not find all 7 items.......
In this project, we were learning about homogeneous and heterogeneous materials. Homogeneous items are things that can't be physically seperated. Heterogeneous items are things that can be physically seperated. To learn this, we were given an unknown liquid with items inside it and were told to name all 6 of them. The materials we received included a graduated cylinder, beakers, funnel paper, a cone, a magnet, and a stove like item. Later, my teacher told us she was mistaken and there were 7 items.
First, we poured out the water into a large beaker, seperating the other items from it by putting them on the funnel paper. From the start we could tell a few items. We could see toothpicks, pebbles, a rock, beans and a seaweed like substance. However, as soon as you use the magnet on it you should see that it is metal filings. I found some salt on the paper while examining the paper, keep that in mind as that was a waste of time.
Later, we put the large beaker on the stove, and waited. After some time, we realized that the dissintegrated material was......salt? Apparently, that lone piece of salt was a misdeamer, as it just came out of the water. In the end we only came up with 5 items out of the 7. Even though we didn't succeed, we learned that the salt water was homogeneous and the rocks and other items were heterogeneous. So in the end even though we didn't succeed, we learned something. Peace.
