...a successful year in 300 chemistry sophomore year, I decided to make the jump and enroll in AP chemistry as my junior year science. The entire first semester of AP chemistry was an uphill battle and was riddled with failures. Any preconceived notions I had about my ability to succeed were seemingly shot down within the first 3 weeks of the class. There were concepts I had never learned and problems I wouldn't have dared touch in my sophomore chemistry class. After a long quarter of struggling, I knew that I needed to make a change. I decided to look at what I was doing wrong in AP chemistry, and what I was doing right in my other classes. As AP chem was the only AP I took junior year, the lens that I looked at it through was much different. I never had expected a class to require so much time after school. I had never experienced poor grades on tests I had studied hours for. Strategies that had worked in the past with other courses were ineffective for this one. Besides the grades, the ideas and thinking strategies I learned after that first quarter resonated throughout my life. Outside of school, I thought more critically about problems to solve, simple and complicated, in everyday life. I found that there are many more ways than one to get from point A to point B....

...I was seven years old when my parents first told me I was going to be a chemist when I grew up. I was always mixing random drinks together, and attempting to pour water out of one bottle and into the next. One of my earliest memories is of me standing on my tiptoes over the sink trying to pour the water in my cup back into a bottle and spilling it all over the countertop. At that age I didn’t understand what chemistry was and how important it would be to me later in life. Ever since I took chemistry for the first time my sophomore year, I knew that chemistry was a career path I wanted to follow. From the very first day, I fell in love with the subject. It was the first class I had and I looked forward to it every day. There was no class I...

...“Chemistry is a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo” (Merriam-Webster. 2011). Thus saying, Chemistry is a major influence on our lives on a daily basis. You find it by the air that you breathe in, the food that you eat, and every object that you can see or touch is a fundamental of Chemistry. Throughout this paper, I will describe why chemistry is important, what is beneficial, and what I found interesting. In order for me to purse my degree in Chemical Engineering, it was a must for me to take Chemistry 1411. First, it was a pre-requisite for the following Chemistry classes for me to take. Second, the basis of this class is a fundamental pertaining to my degree because they have to apply the principles of chemistry to design and operation of immense chemical manufacturing process. I chose this major because my grandfather inspired me from such a young age to be in this field. I can remember him doing all kinds of experiments in his office trying to test and discover things that really drew my interest to this major. My grandfather demonstrated the benefits of Chemistry and showed me how it is ever present in our every day life. He also taught me that Chemistry is always changing in our world around us and I want to be apart of this changing process and help the world benefit from Chemistry. I hope to see myself in a couple years being highly successful and enjoying working for a refinery...

...The Revolution of Chemistry Over the last few centuries the field of chemistry has made great strides. Humans have been experimenting and reaping the benefits of this field for millenniums, yet never had a great understanding it’s fundamentals until the chemical revolution. By the 16th century there had been many advances in the field later to be known as chemistry; smelting and refining of metals, the production of glass ware, pottery and dyes, the development of explosives, artists’ materials, and medicines (Butterfield, 191). Despite the production of these materials, they are not enough to be attributed to a science. As Butterfield suggests, the results of early chemical experiments lacked “adequate intellectual framework which on the one hand embrace the observed data and on the other helps to decide at any moment the direction of the next inquiry” (191). There is no better example of unorganized study than that of alchemy. Although Jensen cites alchemy as being a pillar of modern chemistry, Butterfield suggests it took away from the progression of chemistry into a modern science (191). To understand modern chemistry, we must first examine the origins of it. One of the key terms in chemistry is “elements.” This term was first used by Plato to describe matter. Soon after, Aristotle summarized the theories of earlier philosophers and developed the view that all substances were made of a primary matter. Aristotle defined an element as “one of those bodies into which...

...Chemistry’s Role in Understanding the Dance of Life Is chemistry really important in comprehending life? Is it vital in understanding biology? Can we understand biology or the life per se without the presence of chemistry? As a cliché’ of most textbooks, chemistry is the central science. Meaning it all encompasses the branches of science including biology and physics. And if we try to define what is chemistry, it is said to be the branch of science concerning with the study of matter and the changes it undergoes and the factors that affects these changes. We, the humans, are living things and we are considered to be matter. Living things perform the best gift of God which is life. And the study of life is said to be biology. So therefore, with this simple logic, we can say that chemistry and biology are interrelated with each other. We can’t understand life without some basic knowledge of chemistry. Chemistry is so imperative in understanding life. Specially, the processes that are occurring in our body. We may define the terms respiration, digestion, metabolism, and reproduction scientifically but without proper information about the chemical processes we can’t really appreciate and discern them. Why we breath, digest, metabolize and reproduce has something to do with the latter. Chemistry is very necessary and ponderous in understanding different fields that is associated with the life of plants (botany), animals (zoology), minute organisms...

...Importance of Chemistry in Daily Life Most people have chosen to write their essay about how chemistry has played an important role in everyday life. I have chosen to ask, how doesn't it play a role in everyday life? The simple fact is that chemistry plays an important role in every person's daily activities from the moment we're born. So what role does chemistry really play in everyday life? Well, this involvement usually begins first thing each morning. Most people wake up to an alarm or radio. These common household items contain batteries, which make them very chemically dependent. These batteries contain positive and negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household items. Things like household cleaners and water purification systems are vitally dependent on chemistry. Without chemistry something as simple as scrubbing a toilet without fear of severe burns or small explosions might not be possible. Next, though it isn?t widely known, chemistry is also heavily involved with the manufacturing of things such as makeup and soap. Each time you bathe you are witnessing chemistry at work. Chemicals such as cetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair and skin. Without chemistry, these materials...

...English – The Periodic Table Online Summary The Periodic Table' gives an insight into the importance of chemistry in Levi's life. On a very basic level it probably saved him at Auschwitz, where his professional experience meant he was selected for work in one of the IG Farben synthetic rubber factories attatched to the concentration camp ('Cerium') - far preferable to the back-breaking physical labour he would otherwise have had to perform. Chemistry also provided Levi with a living before and after the war. But Levi looked for more than simply 'the tools to earn his living and have a secure life.' In 'Hydrogen' Levi expresses what chemistry meant to him as a school boy: 'An indefinite cloud of future potentialities'...from which 'cloud I expected my law, the principle of order in me, around me and in the world.' In 'Iron', as a chemistry degree student and with the war looming with all the terrible consequences that it would have for him, Levi explains to his friend Sandro how his view of chemistry has developed: Sandro was surprised when I tried to explain to him some of the ideas that at the time I was confusedly cultivating. That the nobility of man, acquired in a hundred centuries of trial and error, lay in making himself the conquerer of matter, and that I had enrolled in chemistry because I wanted to remain faithful to this nobility. That conquering matter is to understand it, and understanding matter is necessary to understanding the universe and ourselves: ...
