Reflection 2


Reflection 2

 

In the second part of Academic Reading and Writing we studied about how to write essays. We wrote two essays so I am going to write about them, how the course helped me to improve my writing skills, how I will use my skills in the future and how good writing skills are important for future success.

About the first essay I choose the topic it was an interesting topic to read but writing about was hard because of the difficult vocabulary. When I was writing I felt that I had poor vocabulary because I didn’t use a wide range of words. About the second essay we were suppose to write about some contents of a video that we watched. When I was writing I felt like it was something easy to do, I read the sentences then I used my own word that different from the words of the websites. My writing skills have improved since the beginning of the course because I really read a lot of good essays. I think I would use my skills in my future job because most of jobs need to write about how I did the assignment. Good writing skills are important for future success because my work mates would to writing tasks so I would have a job.

What I enjoyed in this course is that I used technology more often to do my work and the fact that my writing skills are getting better. And I hope it was helpful to everyone.

How stuff works

 

Introduction:

Annie Leonard is the person who made the Story of Stuff (2007). It is a short animated documentary that Annie Leonard talks about the true five stages which they are extraction, production, distribution, consumption and disposal that most products go through.

Extraction:

"Extraction means taking the planet’s resources- wood, minerals, coal, fossil fuel, water, plants, animals, and soil out of the earth and starting their journey through the materials economy"(2007). Extraction can have bad effects on the environment, one example is that the earth works in a way that it could renew its natural sources at a certain time but the problem is that people in that field consuming and trashing more than the earth can renew .on top of that the process of extraction causes destroying of forests , climate change and creating pollution .one of  the health problems caused by extraction is it increased the percentage of some diseases like asthma, respiratory and other ailments.

 Production:

Production is "the processes and methods used to transform tangible inputs (raw materials, semi-finished goods, subassemblies) and intangible inputs (ideas, information, knowledge) into goods or services"(What is production? definition and meaning, 2013). To produce goods to sell to consumer there are factors which they are labor, funds and raw materials. In this process they add poisoned chemical to the earth's natural resources to create poisoned products. Most people who catch poisons are the factory workers. Protecting people in the workplace is a basic job of companies but workers are still getting poison by consumer goods. Companies move their factories overseas to places where workers have fewer rights and fewer earnings, in a place where public cannot access to get information about the companies work.


Distribution:

Distribution "is about how a business gets its products to the customers"(Riley, J.2012).Transporting and selling all goods quickly and inexpensively are part of distribution. "The objective of distribution is clear. It is: To make products available in the right place at the right time in the right quantities"(Riley, J.2012). Distributing causes environmental problems such as transporting all goods from the factory to shopping malls and stores can lead to road traffics which it will increase greenhouse gases that will harm the planet. Distribution has a bad health impact on workers in the company and the costumers. The bad health effect on the workers, who get a low payment to cover their health care, is it increases their stress. When it comes to consumers instead of walking to local community they stress their selves by driving to malls.


 Consumption:

The percentage of consumption nowadays is not reasonable and not equal so it needs to be changed. "Products that no-one in their right mind could truly justify as necessary, adorn every shelf and showroom, enticing towards wasteful and thoughtless consumption. Regrettably, this is considered part of the acceptable goal of 'economic growth"(Consumerism and Over-consumption. 2013). Consumption has bad effects on people physical and mental health. In the recent years the typical of workers is working additional hours which it leads to more consumption, watching TV for hours and spending money on buying products. The most dangerous act of consumption is trashing the planet and the neighborhood.

Disposal:
Disposal is "the act or means of getting rid of something"(disposal - definition of disposal by the Free Online Dictionary, Thesaurus and Encyclopedia. 2013). All the products those no longer are useable or they are waste their going to disposed by burning them or dumping them or their going to recycle. Recycling would not be a good idea if the products had a high percentage of toxic. Waste would pollute the air, water and land if they have been burned or dumped. Disposal has bad health effect on all creatures, the air could contain toxics which it would poison the animals or plants which it would effects on the humans who going to eat them.


 Consumerism in the UAE:

One of the main causes of the financial problems in the UAE families and residents is consumerism. The percentage of consumerism is high because the majority of families have a high earning Because of the way of consumerism people in the UAE are stressful and feeling terrible about the challenges of daily life. The most important cause of high consumerism in the UAE is marketing companies they trig people to spend their money to buy products. "Too much consumerism is harmful to individuals, to societies-at-large and, as we can see now, to the entire global community"(Bruce, D.2009).To decrease the percentage of consumerism in the UAE the government should use it sources to protect people from getting in this problem too much consumerism.

Conclusion:
There are five stages that most products go through them "The stages of the cycle are extraction, production, distribution, consumption and disposal" (Kim, B.2011). In extraction they use the planet's resources. In production they change the planet's resources into products those can be use. In distribution they transport the products to stores to sell them. People consume more than they need. All products that not useable they going to disposing. Consumerism in the UAE causes an enormous financial problem which it can be solved by the government

Essay 1


Evolution of batteries

Introduction:

The main purpose of batteries is to generate electrical energy.  From about the end of the 19th century, batteries were the most important source of electricity.

Early history:

In 1749 Benjamin Franklin, used the word battery to express a group of connected capacitors for an experience with electricity. In 1780, Luigi Galvani was doing an experiment on a frog. The frog's leg moved when he touched it with a scalpel. Galvani thought the energy that caused the movement came from the leg. Alessandro Volta, a scientist, didn’t agree with Luigi Galvani results, putting in his mind that the incident caused by two different metals combined together a moist intermediary. The Voltaic Pile is an invention that was invented in 1800 by Alessandro Volta. The material that used to make the Voltaic Pile was discs of zinc and copper and it produce a current of electricity.

Development:

The Voltaic Pile was not able to transport an electrical current for a long time because of the trouble with the hydrogen bubble that found in the Voltaic Pile. The person who invented was John F. Daniell. The Daniell Cell worked for a longer time than the Volta pile. This battery, produced around 1.1 volts, was used to power devices. In 1838 William Robert Grove a lawyer who turned  into a scientist , improved the wet cell battery and named it the Grove cell , he used a platinum electrode held in nitric acid and a zinc electrode in zinc sulfate to create around 12 amps of current at around 1.8 volts . He also invented the first fuel cell, it worked by joining hydrogen and oxygen. The person who invented the first rechargeable battery was Gaston Plante and it was a lead acid battery. Plante designed the battery to store electrical energy. It was first place to use to keep the lights on in railroad cars stopped at train stations and given standby power for utilities. In 1866 Georges invented the first wet cell using crashed manganese dioxide mixed with a little carbon as the positive electrode and a zinc rod as the negative pole. The dry cell batteries were successful until 1881 when Carl Gassner invented the first one. Waldemar Jungner invented a battery better than the lead acid batteries in 1899 and it used alkaline electrolyte but it was more expensive. Thomas Alva Edison developed the alkaline battery into a storage battery. It worked by nickelic oxide and iron.

Nowadays and in the future:

In the last resent years, scientist invented batteries recharge in less time. The sugar battery is a battery works by organic materials like apple and soda noncarbonated. "Recent breakthroughs in battery technology have put us on a track that sounded ridiculous ten years ago: creating batteries out of organic and biodegradable materials that last longer than metallic batteries and can recharge in no time."(Lisa, Z.2010). A group of scientist in Korea developed a fast charge lithium-ion battery that can recharge to 120 times faster than conventional li-ion batteries. In Israel they developed a battery has the ability to be printed on paper.

Conclusion:

The first battery invented because Volta did not agree with Galvani theory. Batteries developed because it did not last for a long time .Then they invented rechargeable batteries. In the recent years they improved every battery so that it work for much longer time and it recharge in less time. In the future batteries might not be the main source of transportable energy.
