Whats That Smell?

Today in science class we had to burn the two sugar cubes in our test tube. The Bunsen Burner was light as one of my classmates put on the glove and held the test tube with the sugar cubes in it over it. Suddenly, the bottom of the test tube started to have a brown substance fizzle up it and the sugar cubes slowly started to vanish. Then the brown substance rocketed up to the top and the bottom of the test tube was orange, and the top of the tube was a greenish yellowish color. After that, we all started to smell a burnt marshmellow or cotton candy kind of smell. We all went to go and look into the test tube and it was hardened. It was still brown but it had a hole in the middle and it looked like tar. Then my teacher, Mrs. Rousseau came over, wrapped the test tube in a towel, and broke it with a hammer so we could see it better. We took a little piece of it, observed it under a microscope, and it looked like a bunch of spider webs. Then after that we felt it and it was hard on one side and smooth on the other. Our prediction was that the hard side was what formed on the sides of the test tube, and the smooth part was on the inside. That lab was one of the funnest labs of the year, and it certaintly had me saying, what is that smell.

H1N1 Virus

The swine flu has been one of the major problems in the world ever since it has hit America. Many people in the world have already gotten this sickness and have died including our relatives, and friends. The "Swine Flu" which is also called the Novel H1N1 virus has already had a wide spread in 41 of 50 states in America and is also in other countries, but the country that has taken the biggest hit is Mexico. This fatal sickness came from swine which also means pig and it started in Mexico. Now it is all around our world from the north pole to the south pole. One of the many ways to get it is from not covering coughs and sneezes. They are already making vaccines but now, so many people are getting the flu that they are running out of vaccines and not all of the people are getting cured. The way that you can know if you have it is if you have a sore throght, are coughing, sneezing, and if you are short on breath or you are weezing. It is up to us to stop this sickness, and we have to do it now.

Flamingo one-legged mysteries

One of the many mysteries in the world is why flamingos stand on one leg and how they sleep. These little pink, furry, and cute animals are one of the coolest and wierdest animals in the whole entire world and are in zoos so we can see there beautiful pink feathers and see them hop aurond from place to place on one leg. In September of 2009, a scientist named Matthew Anderson, went to the philidelphia zoo to examine flamingos, and how they sleep and why they stand on one leg. Many of the theories that they had were that the flamingos legs would tire out, or because of thermorgluation, but finally the scientist Matthew Anderson found what he was looking for, the real reason why flamingos stand on one leg. First, the reason why they do that is because, they can conserve body heat. Also, it would make them a lot faster to get from place to place. Another cool thing about flamingos, is that when they sleep, they bend there head to the right and not the left when they rest, which is the oppisite side, so there head is not on a surface. The beautiful birds also still stand on one leg when it sleeps. All of these reasons made me feel like flamingos were very wierd, but cool. You now know one of the greatest mysteries about animals in the world, the flamingo, and the real story on why it stands on one leg and why they sleep with one leg.
