Summary of "A Bright Idea within Reach "

Reserves organic fuels in UAE are difficult because it will eventually run out and scientists have found a renewable energy source that can be an alternate to the fuel reduction. Dealers were mainly exporting the solar panel because these products had a small market in the UAE. Also, Dubai Electricity and Water Authority did not have a policy on the use of solar panels which was another factor for the small market of solar power equipment. Solar power can have a great effect in the country’s economy, and environment other than being a great alternative for the reduction of fossil fuel. As the population expands, the need of renewable and sustainable source of energy should rise because fossil fuel cannot last forever.

My Reflection to the Course

               After having around three months in academic writing and reading 1, I have learned many things that improved my learning skills through this semester. I have learned how to find and highlight main ideas in an article, make notes to the important information, and summarize an article. Without acquiring the previous skill, I would not be able to write an essay that requires reading articles to get information needed to support my topic. Also, I learned that plagiarizing meant claiming other people’s information to be you. Plagiarism can lead to legal suit and in HCT student case plagiarism can lead to expulsion. To avoid plagiarism I learn that I could rewrite other people ideas but in my own words after understanding the ideas and highlighting the main points. Also, I was able to take the information that I cannot change and use it as quotation. Moreover, I learned how to use in-line citation and how it can make the appearance of my essay be a bit professional. Before, I did not know how to reference the information that I get, but now I learned how to reference any kind of information, for instance, books, magazine, newspapers, websites, and databases.  I learned how to use useful websites, such as bibme that had eased my work during this semester. Also, I learned how to find useful information from credible sources, for example, HCT library databases. In conclusion, the academic writing and reading course was very useful to me because it taught very useful learning skills that I can use them in my life.

Essay 1: Water Filtration/Purification

Even though our planet contains a large portion of water, which is around 71%, the percentage of drinkable water doesn’t reach 3%.  With the huge daily consumption of water, and lack of responsibility and awareness, the fact of losing all drinkable water is inevitable. From the concept of “necessity is the mother of invention”, people started to look out for the ideas of making sea water drinkable. Water purification is a process that takes more than one phase to convert the sea water to drinkable water. In this essay, I will write about the early history of water purification, development of water purification and present of water purification.

In 2000 B.C., ancient Greek and Sanskrit (Indian) writings illustrated purifying water by heating. The main purpose of water purification is to have better water taste for the reason that people could not differ between pure water and foul water. Also, people did not know if the water were free of contamination.  (Enzler, S, 2011). “Centuries later, Hippocrates also believed good taste in water meant cleanliness and purity of that water” (The History of Water Filters. 2011). Hippocrates used his own crude water filter which was a cloth bag. He used the cloth bag to pour water after it has been boiled. This process will trap sediments that cause the bad taste and smell. 

With centuries pass on, people created and developed methods for water filtration. In the 1800’s, the method of sand filtration was prompted to purify water. . At first, Scottish scientist brought the method of slow sand filtration to United Kingdom. The main disadvantage of slow sand filtration was requiring frequent cleaning. Due to the increasing desire of having pure water, “scientists in the United States designed a rapid sand filter in the late nineteenth century” (The History of Water Filters, 2011). “The rapid sand filter was cleaned by powerful jet streams of water, greatly increasing the efficiency and capacity of the water filter” (The History of Water Filters, 2011).  The sand filtration was created to remove pollutants from storm water runoff, control from storm water quality, and provide limited storm water flow rate (Storm Water Technology Fact Sheet Sand Filters, 2011). It consists of three chambers. The first chamber removes floatable and heavy sediment. The second chamber filters the runoff pollutants through the sand bag. The third chamber discharges either direct to the surface or through the drainage system.

Nowadays, people are still developing and creating methods for the water purification process. In 2007, Abu Hussam created the Sono arsenic filter which helped to purify the ground water from the arsenic element. People earlier did not know that ground water contained arsenic which affected their health and shortened their lives. Also, desalination method removes salt from either seawater or ground water. The process required heating salted water and forcing it through membranes to remove unwanted salts (Eckhardt, G, 2011). Moreover, there is a major concern that the water provided from the municipal were contaminated with Iron due to the way it transported. This concern was aiming to eliminate any probabilities of contaminate drinkable water and may lead to ‘change the plumbing system.

In my opinion, the water purification process is a very essential to the humanity, and the life itself can change dramatically without it. This essay discussed about the early history, development and present development of water purification. People should be grateful for the enormous efforts of finding ways to provide drinkable water. Furthermore, scientists are still looking for new method to convert undrinkable water to the best drinkable condition.

Summary of Riches Await as Earth's Icy North Melts

            Businesses are waiting for the countdown of the results of global warming in the North Artic. Even though global warming has a negative effect on environment, wildlife, and ancient culture which is preserved with ice; countries are competing to gain the valuable materials from the ice melting. Melting of Arctic ice will provide with oil, gas, mineral, fish. Also, it made other shipping paths that can ease and accelerate their shipping's time. Countries around the arctic ice are sending warships to those ice islands to make others feel their existence and tried to solve any conflict peacefully. In the last ten years, countries started to notice the great economic effect of the ice melting and started to initiate their work towards the beneficial effect of global warming. United States, Canada, Russia, Denmark, and Norway are the main countries who are trying to get the best profit of the ice melting in North Arctic.

Summary of Desert Survival

Bedouins try to survive in the desert by finding water and shelter. They are using wells to navigate and find the direction of water. They evolved the ability of tracing clues to predict the location of water. Even though the process of digging a well takes time and effort, mostly they find water. Bedouins use sheepskin to purify the sea water. In worst scenario, Bedouins take water from camels and goats or use the milk of those mammals to survive. Losing even a little dehydrated portion can load to death, so Bedouins have to adjust to the heat of the desert to avoid losing their life.

Summary of Pupils Find the Internet "a Poor Learning Tool"

Students believe that learning from traditional methods is better than using the internet. This goes against making information technology the core of learning. Even though using technology is enjoyable, it very poorly serves in learning. Students believe that anyone can write anything on the internet, and it may have very simple or complex material for learning. Nowadays, computer and the internet are used daily and almost in every subject. But, students are complaining about the kind of behaviors that rise when there is a group work related to technology. The Ministry of Education disagrees and believes that computers are helpful for learning.
