Plasticity Lab Report Conclution

Conclusion

            If cornstarch is mixed with water than it will form a polymer with the property of plasticity. The data my group collected showed that this is true because when we balled the mixture up it because a solid like blob, but when we opened our hands the mixture flowed out like a liquid and that is what plasticity is. The results were that it worked and our observations were that it was runny when we tilted our hands sideways and that when we poked it the mixture became a solid like semi hard jell-o. I think this occurred because this mix is a suspension where if it is under pressure the atoms bunch up and make the mix a solid, when released the atoms settle down and then they flow like a liquid. I think the experiment was very reliable because the only outside variables that could have effected the experiment were that the water could have had chlorine or fluoride that changed the consistory of the mix and changed the way the experiment turned out. Also we could have put into the mix too much/too little water or cornstarch which made the mix more hard or runny, the temperature could have changed the experiment. The experiment was controlled because there were only two ingredients in the mix water and cornstarch. Also the fact that the cornstarch was still unopened until we used it gave us some control over what was in the cornstarch. I learned about the properties of plasticity and what it does to Non-Newtonian fluids. Also this tells me about the way suspension fluids work. This relates to the world in the fact that the mantle has the property of plasticity.

Movie

A few days ago we watched the movie October Sky which is about a boy who launches rockets. This movie relates to rockets in science because in science they launch rockets to the moon and to launch satellites also they use rockets to take data from space and other planets. Also the movie talked about the rocket Sputnik which was the first artificial satellite to orbit the Earth, which was made by the U.S.S.R. which was a world power in the Cold War who launched the first space headed rockets in the world. The movie also talks about a type of math called calculus. Which they used to prove that their rocket did not start the fire that burned a forest to the ground by using a special formula. This also talks about character traits because they cooperate to find the rocket and to make the rocket fuel non-bubble filled. It also tells about self control because the guys don't scream or fight when the rocket burns the forest they give up than try to prove it wrong. They also respect the mining industry and the main persons dad and don't make fun of it or vandalise the place because they get yelled at.

This is a link to my friends blog.

I am responding the blog my friend wrote on Cri-du-chat syndrome it is really sad becauses it makes people dependent on others and they can't function in society and that it is like autism only much worse and it is in 1:20,000 newborns it is slightly more common in female than males. To me this is so sad that there is no treatment and the fact that it affects so many people. To me this is one of the worst illnesses in the world. Also because scientist don't understand it they can't cure it or prevent it so it makes it all the sadder. Plus you think that the kids get this without their knowing. To me even if we go to pluto with a person. It won't be a great an accomplishment as finding a cure for this disease.

Patau's Syndrome

Today I researched a disease called Patau syndrome or Tristan 13 because the children born with this disease have an extra copy of of their parents chromosome. This disease was discovered in 1657 by Eramus Bartholan but it was ascertained by Dr. Klaus Patau in 1960. Some of the symptoms of this disease are a cleft lip, missing an eye, under developed brain (not formed into hemispheres.), lung problems and heart problems mental disorders and extra fingers or toes. There is no cure for this disease but doctors can fix the extra fingers or lung or heart problems but not the brain so they will never be fully cured. Most babies with this disease 82% die during the first month and 5-10% die in the first year most die before adulthood only one man made it to 33yrs old. This disease infects 1:16,000 people. babies are most vulnerable to this disease because you get it when you are born. The cells of the person are deformed because they have an extra copy of of the chromosome. there is no way to prevent this disease. They need to know how to cure the brain of this disease. i think this is really sad because it is almost a one way ticket to death and no cure or way to prevent it makes it sad for the kids who have it and their family's. Plus they didn't ask for the disease and they got it.
