Burning Suger

This week in class we did a lab on burning suger.We placed a test tube containing two suger cubes in the flame.In this lab we learned what occures when suger is burned. Soon the buttom of the test tube began to burn so did the suger its self and smoke was coming out from the top of the test tube.After the burnt suger cooled,we observed it.The new substance was a brown-black color.The hardness was somewhat dense and solid and the texture was rough,hard and smooth.In the end my group learned that the suger was not still present because when suger is burnt it turnes into ash and the water in the suger dissolves.In my opinion I think this lab was fun and it help me better understand pysical and chimical changes.

Ever wondered if there are more planest oustide of this solor system.? Well Astronomers announced the discovery of 32 extrasolor planets.Some are five times the mass of Earth and the others are five times heftier than the biggest planet in our solor system Jupiter.Therefore,in class we are studing density which has to do with mass.These new planests were found with the HARPS(High Accuacy Velocity Planet Searcher) spectrograph on the European Southern Observatory's.The HARPS program survayed about 2,000 stars for five years.The particular aim is for looking at solar-type stars for low-mass planets .In my opinion I think this is a great find.These new findings can help us find planets exactly like our own so one day we can explore it and live on it.

Man-sized Dinosaur was a tiny T.Rec

We always thought that the T-rex was the one and only of its kind but,a new find has changed that theroy. A miniture tyrannosauras;It may have been tiny but it had the same fierce features of its bigger cousin.Moreover,the newly discovered dinosaur is not a T-rex but, a turanosaurid.It lived tens of millions of years earlier than its mighty cousin.Weighing in at a measley 150 pounds with a body length of just 9 feet(2.7cm).This new find remians unearthed in the northeast of China .Likewise,cientistist found that the Tyranosaurid(Raptorex)had tiny forelimbs,long legs for quick runnig,powerful jaw muscles,an oversized head,and an enlarged olfactory bulbs that suggestes that this predetor had an expert sense of smell."Many of these traits have never been found in anything but the big brutes"said Paul Sereno of the University of Chicago.All in All i think that this dicovery is intresting but, what if this is a baby dinosuar?.

October Sky

The movie October Sky was greatly connected to Science and Math.Also character education traits are showed in this inspering movie.A science/ math connection is when Homer and Quentin proved their innocence by using math.During on of their luanches the boys luanch a rocket that flies very high.The rocket falls in the a forest soon the boys are acussed of starting a fire near the mine shacks.They order the boys to burn the shack they use to build rockets.With the help of his new found freind Quentin they prove their innocence by using algebra.Homer explains that accourding to his calculations the rocket could not have went the distance they climed based on the exiliration.The boys even use math calculations to retrace were the rockets fell so they can show the police the evidence.Character is very important in this movie.The character triat that showed the most is assertion.For example,in the movie the boys failed more than once and they still kept trying their and their persiverence payed of by helping them enter the science fair and leaving helping them leave Coalwood to go to college.

Canavan disorder

Canaven Disease is rare .Discovered in 1931 there have been only 30 reported cases in the United States ,but one in five thousand Ashkenazi Jews are diagnosed.This disorder is most common in children of Jewish decent. A child with canaven disease may experience many symptoms.For example ,lack of head control ,reduced visual responsiveness and abnormal muscle tone.Likewise at the molecular level 17 chromosomes that causes a dificiency of an enzyme callled aspartocecylase.In order for a child to be affected they have to inherit one allele of the mutated gene from each parent.A life span of an infant withCanavan Disease does not live long.They will die before the age of four.When I read this blog it made me feel sad because those children with the disorder will not live for a long time.they will not even begin thier lifes.It makes me thankful for what I have.

Genetic Disorders(Dwarfism 411)

There are many disease in the World,but Dwarfism is well known around the world.Commonly known as midgits or little people the people with this disorder can live long lives.They have a normal intelligence.This disease was discovered in 1967 by Pierre Maroteaux .In Addition, the symptoms is complications is when the cartilage has difficulty converting to a bone mostly in ling bones.There is also the symptom of an enlarged head.Dwarfism is not a disease therefore there is no cure.In a world population a person in the shortest 3% of a population may be diagnosed with dwarfism.Ferthermore,the hieght thatis considerd very short depends on the average for a given population,as difined by gender, race and ethnicity.In the Molecular level dwarfism is caused by problems with the growth hormones,especially growth hormones.What I thought about this disorder is that it is sad that they are so short because they can live normal lives but it will not seem normal.They may not be able to do some things that normal hieght people can do.
