Barbie Project (Blog #1)

Today in class, we were introduced what our Barbie project was going to be about. We were each given a barbie, rubber bands, measuring tape, as well as a thin rope which was optional to use. With these provided, we had to tie a rubber band on the doll’s leg, and make a bungee rope for her to safely jump without hitting the ground, but getting as close to the floor as possible. On the last day of our project, we were assigned to do a competition of which group had the best calculation to prepare for the best bungee jump. Furthermore, my group members for this project includes me, Arianna and June.
Basically, we started out by measuring everything such as the height of the desk from the floor which was 75cm, the weight of the barbie, which was 94.46g, and height of the barbie, 31cm. After we did that, we measured how many times she would fit between the 75 cm, which was about two times, and a little bit more. We first tried out using 5 bands (not including the one that was tied on her foot) and that worked perfectly fine. To further our investigation, we tried to do one in 150cm. Because we doubled the height, we also increased the amount of rubber bands by doubles which is 10. After that, we noticed that there was some space to fit just one more band, so we used 11 bands in total (again, not including the one band we used to tie her foot). Because this worked well, we recognized that we could write an equation which was: The Number of Rubber Bands = 2H (height) + 1.
We tried our experiment, and observed several times to see if she would hit the floor, or if it was too close, since we didn’t want our barbie to die. Not only that, but our group came up with the idea of also including the force of gravity into our equation (9.8m/s₂), since Arianna believed that it also influenced the way it worked. Furthermore, the problems we confronted with was trying to find out the pattern. We still don’t have enough data to really make sure that our equation is realistic. My predictions about it is that it won’t be exactly precise, but would somehow be close to the actual answer. Meaning that it might not help us get the perfect amount of rubber bands needed, but it would be very close.
On the other hand, the plan for my next class is to try out doubling the height to 300cm with 23 rubber bands to really see if our equation works. However, I’m not so sure if this would work since our classroom might not be 300cm in height, or who will put the meter stick that high. Due to that, I believe that we should try to start again with a smaller height, and see how that works. Not only that, but we will also try to see how much cm the barbie would go down with 1 rubber band, so that it helps even more with our equation. I hope that by next class, we will be able to find an accurate pattern for our project soon!

To Kill a Mocking Bird Questions

Question 1: Is the Quotas a solution of racism? Will it change the future in a positive way?

Question 2: Is racism getting better or worse? In what ways?

Question 3: How does racial inferiority influence societies?

Core Values and Life Goals

My personal life goal right now is to improve my baking skills, and to also start choosing what I want to do in my life in the future. Anyways, currently to develop my skills in baking, I will try to bake once per week. However, it is hard since I have to much things to do such as homework, or studying for tests. Due to that, I think I can only accomplish this goal during vacation. Moving on, my core values reflections where I need to work on would be "curious". It seems that like I try hard to answer questions on my own, instead, I will ask questions during class or anytime when it pops up! The teacher's core value comments was I believe responsibility, but had to work on risk taking.

Vida Complicada...

O Enem (Exame Nacional do Ensino Médio) foi criado para avaliar os conhecimentos dos estudantes que terminaram o ensino médio. Algumas instituições vêm utilizando nos últimos anos essa nota para o ingresso na universidade. No entanto, não são todas as instituições que útilizam só isso porque depende das notas dos outros candidatos que fizeram o vestibular. Por exemplo, na Fuvest (fundação para vestibular), o Enem tem peso 1 e o vestibular peso 4.
Na Coreia, tem um exame muito difícil e grande para entrar na universidade. Além disso, o candidato deve apresentar boas notas no ensino médio (GPA) e escrever uma redação para se apresentar na universidade. Se o candidato estava fora da Coreia mais de 3 anos incluindo o 10° ano do ensino médio, o teste é diferente e mais facil. Caso o candidato estava fora da Coreia do primeiro ao décimo ano, está isento do exame, mas precisa apresentar um bom GPA e atividades extracurriculares.
Nos Estados Unidos, o processo de ingresso na universidade é consiste em: a nota do GPA (Grade Point Average) e do SAT (Scholastic Aptitude Test), uma redação, atividades extracurriculares e cartas de recomendação escritas pelos professores do ensino médio.
Eu acho que as escolas no Brasil têm que melhorar a qualidade do ensino  médio para que os candidatos estejam mais preparados para fazer o Enem. Na Coreia, as escolas realmente preparam por 3 anos os candidatos. Por isso, os estudantes coreanos no dia do exame dizem: “Eu estudei a vida inteira para este dia.” Nos Estados Unidos, o sistema de ingresso faz com que o aluno desde o 9° ano comece a construir o seu GPA até o 12° ano. Esse processo garante que o candidato estude bastante durante toda a vida escolar. Já no Brasil, o candidato não precisa apresentar bom desenvolvimento durante o ensino médio, ou seja, o candidato pode não ter feito um curso bom. Por isso, acredito que o acesso a universidade deveria ser mais democrático e mais justo porque da maneira como é hoje, o exame é mais difícil do que o conteúdo apresentado durante o ensino médio.

                      

Internal vs. External?

There are so many information, and details for the internal factors, however, I believe that the biggest difference they show among the three societies (Northern, Middle, and Southern) would be external because the geography and the environment is totally different. For example, for New England, the climate was very cold, which resulted in having less mosquitoes (no diseases such as malaria, or yellow fever). Not only that, but the economy was based on trade since the soil wasn’t rich to grow abundant crops, due to cold weather. Lastly, this colony had a war with the Pequots, which resulted in the Pequot War (which was the bloodiest war in colonial history).
Moving on, for the Southern colony, Virginia, the climate was very warm. Due to that, there was long growing season, however because they had settled in the swampy area (James River), there were many mosquitoes, as well as not-fresh water. Because of this, vector-borne diseases, fecal-oral diseases were common. As mentioned before, because of the fertile soil, the economy was based on cash crops (a.k.a. tobacco). Additionally, they had conflicts with the Powhatans which led to bloody slaughter, annihilate due to religion, and racism, and burnt down houses as well as crops.
Lastly, the middle colony had a moderate climate, and mixed economy which was based both on trade as well as agriculture. Not only that, but unlike the other colonies, they had peaceful relationships with the Native Americans. Overall, these different facts of geography, and environment had changed, and defined the difference between the North, Middle, and the Southern Colony of America.

Will China get better?

In the year 2050, I predict that the energy situation in China won’t be great in condition, however, I do believe that it will become at least better than today. These days, one of the biggest problems in the world is about how much coal China is using. According to the National Geographic, since 2008, China’s mostly used energy source is coal as mentioned above (80%). Furthermore, the renewable energy they are using is only about 13%. It has been proven that China is using more coal than any other country (including the U.S.). For United states it is 501.9 Mtoe (energy use in million tonnes of oil equivalent), whereas for China, it is 1839.4 Mtoe. The International Energy Agency’s 2013 World Outlook said, “Two thirds of future growth in energy demand will come from Asia, led by both China and India." Additionally, what makes it worse is that this country is the largest emitter of the greenhouse gases.
Currently, there had been several news world wide talking about how the air pollution was so bad that the people couldn’t even go outside. Because of this, the government is seeing a huge rise in hospitals since people are constantly checking to see if they have any infectious diseases from the air such as lung cancer. According to Mrs.Beck, she had discussed during class that the problem is: as the poor people develop into middle classes, and become richer, they use more and more energy since they have money to access it. Because of this, the country has to make more energy. Yet, it is sad that the country is consuming less energy than their number of population. The population is 1318 million people, however the energy consumption is 13,380 million barrels of oil equivalent. What gives hope however, is that they are currently taking actions to make things better. Again, the graph from the National Geographic, shows that in 2035, China will slowly change. For example, the percentage of using coal has decreased to 55% from 80%, and renewable energy usage increased to about 27% from 13%. Thus, the hydropower as well as the wind power is the two main renewable energy sources.
        For me, my proposal for China on what would be the best course of action to take is to burn less coal, but instead, to seek for more renewable energy sources. Already, by looking at different sites, it does tell that they are focusing on solar energy, and wind energy, which is amazing. The government announced that their plan is to increase its own solar power capacity to 1.8 GW by 2020. What’s more, is that China is one of the world’s largest producers of photovoltaic cells. Half the hydropower installed worldwide last year was in China. According to research, it is stated that about 11 dams are under construction, and should be done by 2020. Not only that, but solar and biomass electricity are predicted to grow 10 times more during 2010-2020. As you can see, a lot of changes are already being made, due to that, I strongly do believe that there is going to be some changes made to make China a better place than today. A place where people can safely go to tour, breathe normal air, instead of buying cans to actually breathe, and confidently decrease the amount of people visiting the hospitals.

Pocahontas

Screen Shot 2014-11-03 at 12.27.37 PM.png VS. unknown artist
Mary       Van Passe

We believe that the most reliable source in this site was 12) Pocahontas written by Mary Ellen Howe in 1994. The reason is because it was stated in the passage of how she studied about Virginian Indians. Moreover, she evaluated all of the paintings, and in this painting she tried to make Pocahontas as close to reality-looking as possible. Not only that, she didn’t have any intentions in making money and as she said that her motive to this masterpiece is that she wanted to portray this beautiful woman with a great story and didn't want to publicize her story. This painting is the most reliable because the intentions are correct and much research was done from a secondary source which wasn’t affected by emotion and didn't have any historical conflicts with the Powhatans. This document may be compared to the Pocahontas painted by Simon van de Passe, and as well as Booton Hall Portrait painted by unknown English artist in likely 1700s. What she changed was that she put brighter colors like her beaver hat was white, her hair pitch black, and her skin tone was a bit darker, and painted it closer to an actual Powhatan woman. What she did similar to van Passe was the same dimpled chin and the high cheekbones. Furthermore, as you can see in the paintings above, you can tell that they are quite similar to each other. However, these were the slight few changes that were made. Lastly, we may conclude that we now know the estimate of Pocahontas’s true appearance which was most reliably brought by Mary Ellen Howe through her research and pure motives to recreate such a beauty.
