Pictures Of Symbyosis

My science class was assigned a project. This project was to take a picture of a symbiotic relationship in our township. Symbiosis is a relationship between two living things.There are three types of symbiosis. The first type of symbiosis is mutualism. In mutualism both organisms benefit from their reletionship. One example of mutualism is a honey bee and a flower. While the bee gets the nectar that it needs the flower gets pollenated. Another type of symbiobis is commensalism. Commensalism is where one organism benefits while the other is unharmed. An example of commensalism is a tree with a vine hanging from it. The vine gets something to leen on while the tree does not get or lose anything it needs. The last form of symbiosis is parasatism. Parasatism is when one organism benefits and the other one is unharmed. An example of parasatism is a dog with a flea in its fur The flea gets nutrients from the dogs blood which causes the dog to lose blood.
I got a picture of a tree with weeds on its roots. This is an example of parasatism becauses the tree loses some of its water because the weeds which  damage its roots then absorb the water the tree loses for itself. It is also possible that this is an example of commensalism because the trees roots might have been cut before the weeds grew in allowing the weeds to gain the water it needed without harming the tree. I think this project was an excellent idea because instead of doing normal homework we got to experiment with technology and see how beautiful nature is.

Boom Blox!!

School as many people know it is where you have to go in order to learn, it is also known as the most boring place in the world. However that is not the case at my science class or atleast the boring part isn't. In science class we played the wii. It was for "educational" purposes. The game we played was called Boom Blox. The point of the game is basically to complete all the various objectives and mini games. You start by doing training which gets you used to the various mini games and controls. After that you start completing objectives which usually involves making boxes explode, disappear and break. This game has a lot to do with competition in the enviorment. I know this because the class had to answer questions on a worksheet while we were playing the game. The game relates to competition because you have to be quick thinker in order to get the highest score possible. Animals in the wild have to do the same thing because they have to think quickly in order to get the most nutrients and to remain safe. I believe that this was a good oppurtunity to learn in a fun way. It gets rid of the repetitive nature in school that most people don't like. It is much more fun and cretive to do then to take notes and tests.

Scientists hope to make a car thats faster than a bullet!

British engineers hope to build a rocket powered vehicle that can travel faster than 1000 miles an hour. The name of this car is the Bloodhound SSC and will be piloted by Andy Green. The Bloodhound can travel faster than a bullet shot from a hand gun if it reaches this speed. According to its designers this car is more advanced than most spacecraft capable of accelerating 0-1050 in forty seconds. It will have the first ever mixed power of a hybrid rocket motor and a jet engine that is currently used on the Eurofighter Typhoon. If all goes successfully it is hoped that the car will be ready for testing by 2011. The purpose of the Bloodhound is not to break a record however. It is to inspire future generations to take careers in science,math and engineering.
I think that this car would not be as inspirational to kids as they hope. Most kids and teens probably will not remember this car when they get to college. This car will achieve much in the technological industry and lead to big discoveries. However it looks like it will be very expensive to make. Since most countries are in a recession it would be even more expensive to purchase all the parts and fuel. England should wait until their economy gets before they make this car.

New research suggests dinosaurs grew really big by not chewing their food

Sauropods are an extinct type of dinosaur that had a long neck and ate vegetation. Sauropods weighed up to 80 metric tons and up to 23 feet tall. Scientists believe that Sauropods were such a large size to discourage large predators from eating them. How they kept their massive size remained mysterious. Herbivores(plant eaters) were thought to have very few teeth and were thought to have eaten their food whole. They browsed large areas without moving much because of their extremely long necks and consumed large quantities of vegetation in a short period of time.  Martin Sander a paleontologist at the University of Bonn in Germany stated that "You can only have this neck if you don't chew your food, otherwise your head would be full of teeth and too heavy to support."
 According to Paul Upchurch an expert on sauropods from the University College of London most paleontologists agree that feeding is the key to sauropod magnetism. In order to outgrow their predators sauropods would need two things large amounts of food and a way to reach their full size quickly. In order to survive, sauropods needed to reach their full size quickly. Their bones show that they would reach adulthood in 20 to 30 years which is quick by dinosaur time. This told scientists that they had a high metabolic rate and were warm blooded. If the sauropods did chew their food they would have had a mouth full of teeth and their fore a shorter neck. They would then not be able to consume as much food this way and would not be able to reach their full size. Therefore it is very likely that if the sauropods did chew their food they would have reached extinction before the mass extinction 65 million years ago.

Water Cycle

In class we studied the water cycle and how we effect it. In order to get a better understanding of the water cycle we did an activity that involved the whole class. We divided the class into three sections the clouds, the bodies of water, and the human use of water. Each section has a different purpose the clouds take water from the bodies of water and the human use of water which is called evaporation( we used spoons to put water into a cup). When the cloud(cup) is full it rains(pours) on a different location(a body of water or a human use of water). The bodies of water hold the largest quantities of water and transfer water to each other. The human use of water takes water from major bodies and pollutes it(polluted water was blue). Then the clouds take the polluted water and dump it into another body of water such as the ocean. This experiment demonstrates how water gets to different locations and how human use of water effects the envoirment. It was also very fun.

Kites

In science class we made kites to learn about the weather. My kite's name was The Weather Forecast it was aerodynamically designed. Even though it would have been able to soar high in the sky it didn't because there was a very weak local wind when we flew our kites. It did however get off the ground when I ran letting the kite trail behind me. I learned a lot about wind from making and flying kites such as a perfect place to fly your kite is at the beach because of sea and land breezes which help your kite stay airborne.

social studies society advancement homework

Television has made the greatest impact on society since the 70's. Since it is so enjoyable people spend more time watching T.V. than doing other outdoor activities. Television has influenced our culture in many ways including that it is a big part of a lot of teens daily live. Industries that make television shows become rich very quickly. Television has its ups and downs but no matter what it is the greatestimpact on todays society than anything else.

Second current event for trimester 2(new reasons for the downfall of the Mayan empire)

The Mayan empire was remembered for being one of the greatest empires in the renaissance period. The Mayans built gigantic temples/pyramids, had a developed culture, were advanced in the study of astrology, and had a very powerful army so they were very advaned for their time as well. Their are hundreds of theories about the downfall of the Mayan empire including famine, over population and a natural disaster. However a satitellite program called SERVIR which was origanally developed to help combat wildfires, improve land use, and assist with natural disaster responses has found traces of the Mayan's hidden and possible disastorous agricultural past. Recent research adds that another factor may have been climate change and since Mayans maintained a slash and burn agriculture a climate change could have drastically changed their way of farming. The data collected stated that a slash and burn agriculture and the conversion of wetlands may have induced a drought and may have increased the temperature in a local area. The researchers at SERVIR are now showing Central and South American countries how this may affect them and telling them to keep up with the world-wide climate change so that they don't end up like the Mayans.Check out this link http://n/http://news.nationalgeographic.com/news/2008/02/080229-servir-maya_2.html

Class Response 1 - Chemistry

In science class we are learning about chemistry. In chemistry we learned about matter and how it makes up all physical things. Matter takes up space, and the amount of space matter takes up is called volume. The amount of matter in an object is called mass. Mass is also the reason an object has weight. Weight changes under certain conditions which makes weight not constant. The force of attraction between objects is called gravity. Gravity is one factor that determines an objects weight. The opposite of gravity is interia- the resistance of an object. I did many science experiments in class too.

The experiments I did in science class were very interesting. My favorite experiment was when my group and I put different types of chemicals in a plastic glass to see which liquid would be at the top and which would be at the bottom. The liquid with the highest density would be at the bottom while the liquid with the lowest density would be at the top. In the End the colors of the liquids made a rainbow because of where each liquid floated. My next favorite activity I did was when we learned how to find the volume, density or the mass of an object by using the "Magic Pyramid." The magic pyramid is a formula chart. It tells you how you can find the mass, volume or the density of an object. Overall I think Chemistry is my favorite unit yet.

Chemistry is very fun to learn. It is even more fun than biology. Even though chemistry is not yet over I think the rest of it will be just as fun. Right now my class is researching chemists. Me and my partner are researching a chemist who shared a nobel prize with her husband in radiology. I hope the rest of chemistry is fun!
