In class we are learning about cnidarians and sponges. There are two organisms classified as cnidarians: polyps and Medusa. Medusa are jellyfish while polyps are like sea anemones. If you have seen the movie "Finding Nemo", Marlin and Nemo lived in a polyp. Polyps and Medusa share characteristics such as stinging cells to catch pray and an internal cavity to hold and digest foods. Cnidarians reproduce asexually and sexually. Polyps reproduce asexually by shedding there top rings to create tiny Medusa. Medusa reproduce sexually to create polyps. Polyps can create humongous coral reefs by anchoring there body on a hard surface and creating a hard exoskeleton that will remain there even after they die. These coral reefs are home to the most underwater animals and provide shelter and food to fish. Sponges are barrel like organisms that hardly move. When they are born they swim around to find a nice place to settle and anchor there bodies where they can grow up into adult life. Sponges feed and get there oxygen from water that passes through there bodies. They have a network of needles that go through there body that is like a skeleton for the sponge. these needles also help keep away predators. Sponges do not have separate genders so they produce both sperm and egg cells. when the time is right their instinct tell them to release sperm and eggs into the water where they will join and become a new sponge.

Ferrari recenlty released a new model, the 2010 Ferrari 458 Italia. This car is a newer version of the Ferrari F430. The numbers come from the engine displacement which is 4.8 liters and the 8 cylinder engine. They added the Italia because the makers felt it truly represented Ferrari's homeland, Italy. With the new V8 engine and the 4.8 liter injection, this car maxes out at 570 hp with 9000 revolutions per minute. Like other Ferraris, the 458 Italia has fast acceleration and goes 0-60 in 3.4 seconds. The top speed so far has been 202 mph. The car looks very similar to the F430 but is far superior. The manufacturers aimed to improve evrything about the F430 to make 458 Italia as fast as possible. This new Ferrari competes with the new Audi R8, Aston Martin DBS, the Corvette ZR1, the Nissan GT-R, and the Lamborghini Gallardo. If you recognize these cars you know that this is no idle threat. These cars area top of the line speed machines and are built to be superior to every other car. While car companies have to worry about competing with their rivals we can sit back and enjoy the results. Thank Ferrari and other car companies for making cars like these.

Today in class we did a lab on amorphous solids. An amorphous solid is also known as a slow moving liquid and has characteristics of both solids and liquid. The material we worked with was water and cornstarch mixed together which created a very cool substance called Goop. Goop would turn solid when pressure was applied to it but would turn liquidy when the pressure was released. we also learned about other amorphous solids like glass. Scientists are still debating whether glass was truly an amorphous solid. Studies show that glass from about thirty years drips down to the bottom so that the bottom of the glass is thicker than the top. This means that the glass is slowly dripping from the top down to the bottom. We learned that there are 4 states of matter: solid, liquid, gas, and plasma. Plasma is found mostly in outerspace and is rare on earth. If scientists can find out how to control it it can be very useful and can possibly solve many of our problems with energy. Some substances can go through each of the other phases though. Water can be a solid liquid and a gas.

Scientists have done studies to figure out that wolves generally use logic more than domesticated dogs do. They performed experiments to prove that while wolves trust their senses and instincts, dogs trust what the human tells them to do. In one of the experiments a ball was placed in box A. Both species were able to find the ball in box A. The dogs learned from the humans who told them it was in box A. The wolves sniffed the ball out and found it in box A. Next the scientist moved the ball to box B. The dogs continued to search box A for the ball while the wolves followed their eyes and found it in box B. Scientists found that while this makes wolves superior in using logic, dogs will be better adapting to humans lifestyle which will be valuable to being a good pet.

In the movie, October Sky, there was a boy named, Homer Hickam who was inspired when he saw Sputnik flying in space. He wanted more than anything to build a rocket that can go to space. Homer Hickam lived in a mining town where his dad wanted him to continue the family tradition of working in the mine. His father did not approve of his ambition of creating rockets. Homer and his friends found a deserted hill where they made and shot rockets. Many of their first rockets failed but eventually they got them to work correctly. His town was very proud of him and his sick teacher was very supportive. The police showed up at his school one day and accused Homer and his friends of starting a forest fire with a stray rocket. But using trigonometry or something he proved that the rocket could not have in fact started that fire. With encouragement from his teacher, him and his friends entered in a science fair and won. If they didn't win they probably wouldn't have made this movie so that was predictable. In the end his father accepted him which I knew would happen in the beginning of the movie because every movie is like that. This movie was inspiring because a boy froma poor town followed his draems and did something great.

Klinefelter Syndrome is a disease that only men can get. Men with this disease cannot reproduce because of the extra sex cell that they were born with. This disease was discovered by Dr. Henry Klinefelter. Symptoms include breast cancer, germ cell tumors, diabetes, and arthritis. I feel bad for the people with Klinefelters Syndrome because they can never have biological children and they have a 40% chance of death. I agree with this blog that getting this disease can be catastrophic. However, don't understand how testosterone treatment makes someone look more manly. Overall I think that Klinefelter Syndrome is a horrible disease to get and I can understand how hard life would be for people with this disease.
