High-Speed Data Link Made from Laser Pointers Works Where Wi-Fi Won't

Wi-Fi isn’t always practical--in places like hospitals or labs, for instance, where radio transmitters are prohibited--and physical USB cables can be slow and cumbersome as well. Engineers at National Taipei University of Technology have built a low-cost, easy to implement optical setup that can beam data's across the room twice as fast as USB 2.0 technology using conventional laser pointers. This only cost about $600 and  build and employs the green and red laser pointers for conference rooms. By replacing these batteries in the lasers with a power sources it can switch them on and off rapidly about 500 million times per second rapidly. A two-laser rig can beam a billion bits per second across roughly 30 feet. If you combine these, the signals roughly double the data rate of USB 2.0 or Wi-Fi, and could link together systems in portable labs or medical centers, or simply make it easier to set up networks in places where radio signals might interfere with other equipment.

A Massive Robot Dog Made all from Scrap

This event is about these steampunkish dudes at Mutoid Waste company who have been in the lap of everything we call scrap, making stuff that is beyond even the best sitting in the helm in factories. This picture right over here shows Larry the robotic dog made out of scraps and  is their latest induction to crawl through the gates of the workshop and onto the busy streets of London, breathing fire out of its metal hood with each step forward. The robotic dog has a Citroen 2CV engine fitted inside the metal frames. This took the Mutoid Waste company at least 4 weeks to build and it took a lot of hard work and determination to build it. For the eyes, Larry has a radar detecting device from an airplane scrapyard and some industrial machines parts for the other body components.


This reminds me of when I was in school and we had to create a car using the material given and then we had to race them which is just like how Mutoid Waste company made Larry out of the material given without the racing part. It was really fun! I feel that Mutoid Waste company worked very hard to make this robot and that if they made a business out of this they would make a lot of money.

Autism More Common Than Previously Thought: CDC Report Shows One in 54 Boys Identified

This story is about the recent news about the U.S. Centers for Disease Control and Prevention estimates that 1 in 88 children in the United States has been identified as having an autism spectrum disorder, according to the new study released March 29. This takes place in the Unites States. Autism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behavior. These signs all begin before a child is three years old. Autism affects information processing in the brain by altering how nerve cells and their synapses connect and organize; how this occurs is not well understood. I feel that autism is a very bad disease and that it is sad and that now even more of the boys in America are getting this. The people that don't have autism should be happy that they don't have it. Trust me you don't want to have it. This reminds me of our school, we have many autism students and when you see them you should not laugh at them but instead you should be say hi to them and be nice to them. How would you feel if you were a autistic child? You would probably feel left out and lonely. I bet you wouldn't like that!

When here about more people getting autistic I feel very sad and hurt. And then when I see people making fun of them I get really angry. So one of the solutions that I used was that I told that person that, that person was autistic and that you should stop making fun off them. Then I told them how they would feel if they were autistic! Then the guy went to the autistic kid and apologized to him. And now he plans on joining the autistic club. So for all the people who are out their you should read this article and before you start laughing at autistic kid think about how you would feel you were an autistic kid.

States of Matter Lab!

These are examples of the candles we used!

During the past week we have been doing an abundant amount of labs. We successfully did these labs, Marshmallow lab, Candle lab,  Observing Changes in Matter Lab, and finally the Pouring Gas lab. In this essay I will explain to you what all these labs are. First we will talk about the Candle lab. During this lab, we lighted a birthday candle and observed the changes. But, before we lit the candle, we used some of our senses to observe the physical property of the candle. I first noticed that the candle was very tall, thin, rough, and that it was made out of wax. Mrs. Rousseau lit the candle for us so that we did not start off and fires, then we quickly saw many chemical changes. The candle showed heat, light, and burning wick is turning black. After a little amount of time we discovered two physical changes that the candle was melting and shrinking slowly and slower.

These are examples of some the marshmallows we used!

The next lab we did was the awesome Marshmallow Lab. We did this lab on two different marshmallows, one huge one, one small one. We tore the small marshmallow into two pieces, which was a physical change. Then we ate the small marshmallow and we jotted down how it tasted. I thought it taste scrumptious and sweet in my mouth. The next step that we did was using the Bunsen Burner and that large marshmallow. First, we put the marshmallow over the Bunsen Burner to see what the outcome was. The marshmallow had changed from a sweet and scrumptious white marshmallow to a dark and black hot disgusting marshmallow! This was a physical change because it melted the inside of the marshmallow but was also a chemical change because it was burned by the fire. After the burning, the marshmallow went from a solid to a liquid and solid mixture. Out of this lab I learned that when we burn the marshmallow that it was a chemical change!

This is an example of the candles that we used!

Another lab that we did was the Pouring a Gas Lab. First we lit the candle to start the lab. After this my group mixed the water and the vinegar into the same glass. Then we carefully added some more of the baking soda into the glass. The reaction was quick that I could barely even see it. The liquid exploded and created a white foam to go up quickly and drop all over the edge of the glass. Then we all decided that this was a chemical change. Once the foam came back we slanted the glass over, but we had to do this without making the liquid fall, and then we held it beneath the flame. The flame immediately went out as soon as we did that. Out of this lab I learned that when mixing water and vinegar into the same glass and then add some baking soda it would create white foam.

This is a chart!

The last and final lab we performed was the Observing Changes in Matter Lab. In this lab, we implemented many diverse experiments to sugar cubes. We took a sugar cube and used our senses to examine it. We concluded it was small, white cube-shaped ,sweet. We took two of the cubes and decimated them. This was a physical change because the final outcome was still sugar. Then we took the crushed powder and dissolved it in water performing another physical change. The sugar was still their because we could still taste the sugar. If we could not taste the sugar, we would have noticed that the water had become less pure as it was before we dissolved the sugar in it. Next, we took the last two sugar cubes and put them into a test tube. We used a tong (are used for gripping and lifting tools, or which there are many forms adapted to their specific use) and put them over the Bunsen Burner. My group first saw a yellow liquid sprouting underneath the sugar that was precipitously turning brown. Soon the liquid changed into the color black and we couldn't see the sugar cubes anymore. We concluded that this was a physical change. After a few minutes we took a look at it again. It was bigger than it was before and it was black and burnt.

Procedure Lab!

On Thursday, in science class we  separated a mixture. Inside the cup were 7 mystery objects and our task was discover what were the 7 objects and state our procedure.We were allowed to use 2 graduated beakers, a funnel, a graduated cylinder, cup, spoon, magnet, taunts, paper. The steps to the procedure were:

 Step 1: First you should observe the cup to see what you are going to be touching. 

Step 2 :  Then pour the water from the cup into the graduated cylinder and when you pour the water, make sure that none of the other objects come out with it. Then use the funnel and pour it into the graduated beaker.

Step 3: After that observe the cup again and you will see something black. That is called Metal Filim. Use the magnet to pick up the Metal Filim and then put it into the one of the beakers. It might be hard but if you try your best you will be able to do it. Make sure you get it all out of the cup.

Step 4: Next examine the cup and you will find something white. Those are beans! Put that on the paper and let them dry.

Step 5: Use your pipette to extract some water from the container. See if any object has revealed itself by sight. 

Step 6: Now put your graduated beaker that contains the water and put it on the hot plate and be careful because the hot plates are real hot. Stay away from the hot plate and keep the paper away because it might cause a fire and we know you don't want that. SO BE CAREFUL!!

Step 7: After a minute or two pour out some the water out of the graduated beakers.This will speed up the process of the water boiling.Watch too see if there are any changes in the water. Mark my words" only some of the water".

Step 8:  Now identify all the different objects that you saw and have taken out of the cup. You should have been able to find 6 items. If not check back to see if you left a procedure out.

Step 9:  Finally pour out the rest of your water into the drain. and check to what you have at the bottom of the beaker. At this point, you should have found 7 different objects including the object at the bottom of your graduated beaker.

Step 10: Now since you are done you must clean up all your supplies and including the tray. Then recycle the paper, metal strips and the cup. After that get a cup and paper for the next class and put all the supplies in order. Now you are officially done with this lab!

Hope you had fun!!

Epic Frog Dissection!!

 Wow I actually dissected a frog and I can't believe it! During the past two days we dissected a frog and learned how the frog's organs functions and where they are, what are the organ systems, and how the frog is connected to us. So I got to admit I was pretty scared in the beginning because of the frogs organs, but then when I start to dissect it, I had a tremendous amount of fun. If I were to be able to do it again I would do it. So first lets start what the organs are. The liver: The largest structure of the the body cavity.  This brown colored organ is composed of three parts, or lobes.  The right lobe, the left anterior lobe, and the left posterior lobe.  The liver is not primarily an organ of digestion, it does secrete a digestive juice called bile.  Bile is needed for the proper digestion of fats.Now the Heart:at the top of the liver, the heart is a triangular structure. The left and right atrium can be found at the top of the heart. A single ventricle located at the bottom of the heart. The large vessel extending out from the heart is the conus arteriosis. Lungs: Locate the lungs by looking underneath and behind the heart and liver. They are two spongy organs. The Gall bladder: Lift the lobes of the liver, there will be a small green sac under the liver. The gall bladder, which stores bile(hint: it kind of looks like a booger). Stomach: Curving from underneath the liver is the stomach.  The stomach is the first major site of chemical digestion.  Frogs swallow their meals whole.   Follow the stomach to where it turns into the small intestine.  The pyloric sphincter valve regulates the exit of digested food from the stomach to the small intestine.The Small Intestine:    Leading from the stomach.  The first straight portion of the small intestine is called the duodenum, the curled portion is the ileum.  The ileum is held together by a membrane called the mesentery.  Note the blood vessels running through the mesentery, they will carry absorbed nutrients away from the intestine.  Absorption of digested nutrients occurs in the small intestine. Then comes the Large Intestine:As you follow the small intestine down, it will widen into the large intestine.  The large intestine is also known as the cloaca in the frog.  The cloaca is the last stop before wastes, sperm, or urine exit the frog's body.  (The word "cloaca" means sewer). Then the Spleen:Return to the folds of the mesentery, this dark red spherical object serves as a holding area for blood. Finally the Esophagus: Return to the stomach and follow it upward, where it gets smaller is the beginning of the esophagus.  The esophagus is the tube that leads from the frogs mouth to the stomach.  Open the frogs mouth and find the esophagus, poke your probe into it and see where it leads. 

 Now lets talk about it's systems of the organs. Well you may ask what is the Digestive System? The Digestive System is a complex series of organs and glands that processes food. In order to use the food we eat, our body has to break the food down into smaller molecules that it can process; it also has to excrete waste. The Liver, Gall bladder, Pancreas, Stomach, and Small Intestine are all part of the Digestive System.The circulatory system is an organ system that passes nutrients (such as amino acids, electrolytes and lymph), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases, stabilize body temperature and pH, and to maintain homeostasis.The Respiratory System is made up of the organs in your body that help you to breathe.The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide. The Lungs and Skin are both parts of the Respiratory System.The Nervous System is an organ system containing a network of specialized cells called neurons that coordinate the actions of an animal and transmit signals between different parts of its body. In most animals the nervous system consists of two parts, central and peripheral. Now it is time to talk about how the Frog is connected to us the humans.




The Frog is connected to us in many scientific ways! Frogs and humans similarities are that we both have a stomach, small intestine, large intestine, heart, lungs, pancreas, and gall bladder frogs and human  were that we both have a stomach, small intestine, large intestine, heart, lungs, pancreas, and gallbladder. We both have a reproductive system to build our population.We may not be connected on the outside because size and shape but on the inside we are and this is how. We both have a heart that pumps blood and we both have lungs that give our body oxygen. Frog's reproductive organs are on the inside as where humans' are on the outside. Frogs have white hearts and humans have red hearts. You can see a frogs Esophagus through its mouth, but you can't see it from humans. 

In conclusion, I think I had a very fun time and I wish I can do this again. It was a good experience and I learned a lot about the frogs which helped me learn something about myself. I hope we can do this again someday!

Stomach Churns Lab

Yesterday we focused on hydrogic acids and egg whites. We experimented with four test tubes which were labeled as A,B,C,D. For A we added 10mL of the enzyme pepsin in the test tube. For B we added 5mL of pepsin and then we rinsed the graduated cylinder and added 5 mL of water to the test tub. For C we used clean graduated cylinder 10mL of hydochloric acid to test the test tube. For D we added 5mL of pepsin and then rinsed the cylinder and then added 5mL of hydrchloric acid to test the test tube. Then we finally waited for the next day to wait for the recation to occur.

Chicken Disection

Just recently in our class we dissected a chicken. I know it might said disgusting because even at one time I thought it was disgusting too. But I learned a lot from this dissection which totally changed my opinion. I learned that there is a big difference between the human body and the animal body and the main difference is that our body is way more complex. One reason how I know that is that when you move an animal's muscle it's body will move.Amazing right! But when we try that with our own bodies that won't happen or that would have made our lives way easier. I happy I did this because know I know this difference between our bodies! 

Diffusion Lab

The purpose of the lab was to help us understand the cell membrane inside and outsides. We also learned a key word called diffusion. It is a making a substance that is like a strong chemical and less concentrated. While this is happening molecules try their best to make more space. For example, if we ask two units to fit in one class room they will feel squeezed and whenever the door opens we will all try to get more room. Same with the molecules, they will try to get more space similar to us human beings. Water is a key thing that supports diffusion and it makes the chemicals more diluted and in conclusion it makes the chemicals weaker. Dilution also makes it less concentrated because of osmosis. Osmosis is the movement of the water molecules. Some other words we learned in class were hypertonic, concentration, indicator, and dilute. Hypertonic means high concentration. Concentration means the amount of a substance per defined space. The word dilute means to make it less concentrated. Indictor means a chemical detector for other particles.

In the experiment in class we learned that when we put corn starch in a bag and put it in iodine it turns purple. The cause of this was the permeable membrane. This means to penetrate through the pores, interstices, etc.  It let the iodine pass through the bag into the cornstarch which showed signs of low concentration. Similar to the cell membrane because it controls what goes in and comes out of the cell just like how the permeable membrane let the iodine passes through the baggie. But the difference is that the permeable membrane lets the iodine pass through and the cell membrane lets food and water pass through.  It is important to know how our body works it could decide a better future for ourselves.

One connection that I can make to life is that when a city or state becomes way too populated they try to expand their country. For example, the thirteen colonies. Another connection is if you put water in a cup and knock it down every will rush out. One more connection is when a group of people exit a roller coaster or a movie everyone rush out of a movie theatre or ride, leaving room in the theatre/ride for the next group. Last and not least is that if you are playing basketball all the air just rushes out.                    

Lab Report

Today during the lab I learned that when you put starch with iodine it turns the startch purple. I also learned that if the baggie is a little bit open substance can easily enter the baggie. Even with the tiniest open, substance can easily enter and leave the baggie. I noticed that there was high concentration because I saw tiny purple dots on the baggie.The plastic bag from the experiment acts like the cell membrane, letting in substances that fit in and not letting in other substances that do not. 


I hope we do more lab experiments in the future!
Thank you Ms.Rousseau
