Plasticity Lab

Structure of the Earth:
Plasticity Lab

In science class we performed an experiment that had to do with plasticity. Plasticity is the capability if being molded, receiving shape, or being made to assume a desired form.
In this experiment or lab, we used, cornstarch, water, two small beakers, a spoon, food coloring, and a tray. With these materials we conducted an experiment that made a gooey substance that demonstrated plasticity. First, we made sure we did this lab over a tray to prevent a huge mess. Then, we put about five tablespoons of cornstarch into one beaker. After that we put twenty milliliters of water in the second beaker. Then, we combined them by pouring the water into the cornstarch slowly and mixed the substances together. We also added in about two drops of green food dye. Soon the mixture became harder to stir because it was now thick.
To describe the mixture, I would say that it was gooey and green. When you stirred it the mixture was extremely stiff and hard to mix. This was not the only way that the substance was though. It reacted in different ways depending on how you handled it. When you roll it in your hands, the pressure and heat that is being exerted on the goo, keeps it in a ball, and from falling apart. When you stop rolling it from in between your hands, the goo appears to look like a liquid. In reality it is smooth and hard.
Like I said before, this mixture reacts in different ways depending on how you handle it. Another example is when you stick your finger in the mixture quickly, it just makes a small dent in the substance. Then it returns to its original form. If you push your finger in slowly, it causes your finger to sink, and covers your finger in green goo.
The mixture is similar to the earth's mantle because of heat and pressure. Also there are two layers of the mantle. The top layer has plasticity and the bottom layer is solid. Just like the mixture that I made, it has plasticity and sometimes it can be a solid too.

October Sky Blog

Recently I viewed the film October Sky. This movie was a heart felt film that included many concepts of life.
October Sky is about a young boy named Homer who dreams of building rockets and exploring the vast unknowns of space. One of his inspirations was The Sputnik and the Russians. These were his inspirations because no one dreamed to go into outer space and everyone thought that it was dangerous. Exploring space was completely unheard of and many thought that it could be life threatening too. Unlike them, The Sputnik (a famous spaceship) and the Russians, proved that their beliefs were far different. This was Homer's drive to keep moving forward and to keep him believing that anything is possible.
During this movie, it also showed Homer's family. Homer's dad works at a coal mine and it is a very dangerous job. The dust from the coal can clog your lungs and can make you extremely ill. Also, there is always the possibility that the ceiling can fall on top of you, since it is made of rock. Homer's dad expects that he takes on his job after him, but Homer does not want to take over his dad's job since he is interested in rockets. This does not please his father, but it did not stop Homer. Homer experimented with building rockets with his three close friends throughout a period of time and tried different ways to make the rocket go farther then the previous ones they had tried. As they were doing this one day, one of the rockets went in a different direction and Homer's father yelled at him for the mishap and how it landed near the coalmine.
Soon after all the experimenting and finding a working rocket formula, Homer entered a science fair. There he showed his rocket as an exhibit and won first prize. He was even awarded a scholarship, which were very important (as they still are now) in the 1950's. Along with that Homer and one of his buddies used calculus and magnificent math equations to prove that his rocket did not land where his dad said it did, and that it actually landed in a stream. Something that looked like a rocket landed near the coalmine instead. This proved that Homer was serious about his rocket building and did not want his dad to think that it was just a silly thing to do.
October Sky, also included Character Education traits like cooperation, assertion, respect, empathy, and self-control. Cooperation was shown when the boys were making the rockets together. This trait was necessary to get to their goal because without it nothing could have ever happened. Assertion was shown when Homer's mother stood up to her husband and told him to bring a new rocket piece to Homer when one of his was stolen. She was very brave to do this and I was glad that she stood up for herself and spoke the truth to her husband about how he needed to take interest in their sons hobby. Respect was also shown and not shown in the movie. It wasn't shown when Homer's father did not have respect for his rocket building, and Homer's father showed respect to Homer when he worked in the mines for a couple of days when he was ill. This made him happy because mining is a job he does, and he liked that Homer was taking after him. Empathy is yet another characteristic shown in this film. Homer feels sorry for his teacher Mrs. Riley when she was sick in bed. This means that he knows how she feels even though he did not go through it. Lastly, self- control was shown. Homer was surprisingly calm when his dad yelled at him for shooting a rocket near the mines. He maintained a good attitude and did not yell or fight back.
Overall, October Sky is a great movie that is inspirational and proves that you can accomplish anything you want if you truly try.

Genetic Disorder Response Blog

I read gymnasticsgirl817 's blog and it turned out to be very interesting. It was about the genetic disorder called Turner's Syndrome. Turner's Syndrome is a disease that happens only to women. You see, according to this blog women's genes are XX while men's are XY. Turner's Syndrome is when a women is missing an X gene or one is defective. When I read this blog it was very upsetting to hear all of the possible symptoms of having Turner's Syndrome. For example, some symptoms are, you can be smaller in height, your hands and feet can swell up, you can have droopy eyelids and a short neck. All of these issues are very serious and they can affect the daily activities of the people with this disease. Unfortunately, Turner's Syndrome has no cure yet but some treatments that can be done are, growth hormone injections can be performed to increase the women's height, and apparently estrogen replacement therapy can help the women live a more happy, and productive life.

Clearly, this disease sounds complicated to live with. It is very unfortunate for people with this disease because it makes life a whole lot harder for them. Reading this blog made me feel very fortunate that I don't have to deal with these problems everyday of my life. Although there is no cure for Turner's Syndrome yet, I am sure that there will one day be one and it will help patients with this disease to thrive and be happy and healthy.

Charcot-Marie-Tooth Disease

Charcot-Marie-Tooth Disease

As you may know a genetic disorder is a pathological condition caused by an absent or defective gene. Charcot-Marie-Tooth Disease is yet one of the many genetic disorders that can be found in our world.

This disease is very complex. There are several different types of CMT disease. These include CMT1, CMT2, CMT3, CMT4, and CMTX. It is very unfortunate that there are several different conditions of this disease. All it does is it makes people more vulnerable to have it. In fact 1 in 2,500 people in the U.S. have this disease. Unfortunately more and more people are diagnosed with this disease every day. Before doctors diagnose they look at the patient’s history and family history to see if anyone else in their family has ever had this disease before. This helps to determine weather or not the patient has the disease.
Sadly, there are many symptoms to Charcot-Marie-Tooth Disease. A couple of these symptoms include weakness of the foot and lower leg muscles and it affects both motor and sensory nerves. Also, it can cause people to have a disability in their hands and feet. Therefore, life is made much harder for them. It is a struggle to even do the daily task of brushing your teeth. Unfortunately, there is no known cure for this malfunctioning disease, but some people with the disease go to therapy and sometimes even orthopedic surgery to help “them cope with the disabling symptoms of"CMT disease. Currently there is research being doProxy-Connection: keep-alive
Cache-Control: max-age=0

for CMT disease. There are efforts to “identify more of the mutant genes and proteins that cause the various disease subtypes.”

Overall, this disease makes me feel very upset because it is hard for me to realize that this disease actually exists. Anyone with this CMT disease has a hard life because their motor skills are affected. I guess I take for granted the simple tasks that I do everyday. I cannot imagine not being able to get dressed or brush my teeth on my own. Even for one day. CMT disease patients have to deal with these challenges everyday. Clearly, Charcot-Marie-Tooth disease is very serious and I think that everyone needs to be informed about it so that they know about other people’s troubles when they think that they’ve got it bad.
