Plasticity Reflection

Last week in science class, we did a science lab on amorphis solids. We mixed water and corn starch to make our product (Popcorn not included). To make it more fun, we also added green food coloring to die our hands. After mixing it for a while, it started to become very hard to mix. We knew then to start our experiment. As i picked up a chuck of our result, it was very liquidy. But then as I started to play with it, it became a solid. As soon as i stopped playing with it, it turned back into a solid. With pressure and heat, the experiment is a solid. But as soon as you remove that force, it becomes a liquid. This acts like the Earth's mantle layer because it is forced inbetween the crust and the outer core which is very hot. This is also the reason why the crust is able to sit on top of the mantle. I enjoyed this experiment and loved how it dyed our hands. My mom FREAKED!! I wish all experiments were this fun.

Movie Connection to Science and Cares.

C.A.R.E.S is a program that influences non violence. The movie that we saw had a lot of these rules in them. For example, Henry's dad had to cooperate when he learned that Henry did not want to work in the coal mine he owned. At first, he was against the idea the henry wanted to be a rocket scientist because back then if you would usually take you fathers job, especially when he owns the buissness. It was very hard to get out of a coal mining area once you were in it. The only way you got out is some people got lucky and recieved a football scholarship. Henry tried to play football but he didn't suceed therefore he had to change his plans. His mom on the other hand had respect for Henry with his dream. Respect is the R in C.A.R.E.S. It also seemed like she was happy with whatever her son wanted to do. She would come to see most of all of Henry's rocket launches and she helped to build the rocket some. Another character that showed respect was the welder that would weld Henry's rockets together. Then he died, and Henry had respect for him because he looked back on all the things he did for him. His brother who got the scholarship for football showed assertion (the A in CARES). Assertion means that something is said in a positive manner that is held without a reason. He told Henry many times that the only probable way Henry could get out was on a football scholarship. He denied the offer many times. But then he went on to win the country science fair and lived a happy life. That is, out of the coal mining buissness his dad owned.

The movie we saw also related to science in many ways. The whole movie was about scince to be infact. One way it related was when they got in trouble for setting the forest fire with one of thier rocket. He used math to figue the angle at which it was shot to find where it landed. They proved the police wrong because it was no where near the forest. He also used science when he figured out what to put in the rocket to make it fly. He needed to take the weight and a whole buch of other things. There are many ways science connected to the movie "Rocket Boys."

I recently read an article on sickle cell anemia by Madden07. This disease is mostly found in African countries. Did you know, prior to me telling you, that the human cell is a red, round shape? Well, this disease turns them into a crescent moon shape. One out of twelve African’s have the trait. This does not mean they have the disease, but they can pass it to their offspring resulting in over 2 million having the disease now. After reading this article, I was grossed out that this disease does what it does.

Klinefelter Syndrome

Did you know that there are more than 10,000 diseases that are known to be in humans? Even though there are only 10,000 diseases, there are billions in the world that we have not discovered yet. Klinefelter syndrome is one of the 10,000 diseases. It was discovered in the early 1990's. Some complications are.....            

 

* ADHD           

* Lupus           

* Rehumatoid arthritis           

* Sjogren syndrome           

* Breast cancer           

* Depression           

* Dyslexia           

* Tumors           

* Learning disabilities           

* Lung disease           

* Osteoperosis

 

 As you can see, there are many things that can happen to you if you have this disease. Some symptoms are ........             

 

* Infertility            

* Less hair            

* Enlarged breasts            

* Small,  firm testicles            

* Small penis            

* Tall height  

 

The best treatment for klinefelter syndrome is testosterone therapy. Although only 40% survive the fetal period, the syndrome can starts as an adult. Since when you get older you make the decision to have kids, this disease can make men and only men infertilized. Which in english means, you can't have kids. It is not very probable to get this though. Only 1 out of 10,000 males get this syndrome. There is extra copies of each of the 23 chromosomes for a total of 46 per cell. Males without the syndrome are called xy males but men with it are xxy or some other variable with two different letters but more than the normal amount. They are still considered males though because they have two different chomosomes. In order to make new treatments, scientists would have to understand the elements of.......              

 

* Speech development             

* Behavioral             

* Self-confidence
