I choose two particular articles that relate to the value of chemistry to the benefit of the environment. One is a short article about a rechargeable battery driven by bacteria. The other article is about how US can be converted to 100 percent renewable energy country. I chose these particular articles because of what I truly take away from the course. Through this course, I learned the value of chemistry to our environment. Chemistry has a tremendous importance and contribution to our environment. In the class, we have discussed the issue of pollution in the world we live today. The two articles articulate how we can save and benefit the environment through the combination of chemistry and modern technology. By continuing to be innovative, scientists are achieving tremendous steps toward creating clean environmental friendly energy. By being aware of these important achievements, we all can do something about to help the environment.
Summary of Article #1 Storing energy can make renewables more reliable, but current technologies such as lithium-ion batteries are limited by safety issues, high costs and other factors. The researchers combined, for the first time, two separate microbial energy systems: one that uses bacteria to form acetate from electricity and one to convert the produced acetate back into electricity. The researchers successfully charged the battery over a 16-hour period and discharged it over the next 8 hours, mimicking the day-night pattern typical for solar energy production. They repeated this cycle 15 times in as many days. With further optimization, they say the energy density of the microbial battery could be competitive with conventional technologies. Someday it could help us store energy from local renewable sources safely and at a lower cost than current options.

...Chemistry and Society (Name) CHM/110 Due Date Instructor Chemistry and Society Chemistry is an important part of our society. It is used for manufacturing the products we use, medicine, and just about every other aspect of our lives. This document will discuss how society depends on the accuracy and precision of measurements, the difference between accuracy and precision, and compare and contrast accuracy and precision of different types of measurements used in our daily lives. Accuracy and Precision Since the bulk of this discussion is about measurements, we will start off by discussing the difference between accuracy and precision in that context. When making any kind of a measurement, we need to be able to get as close as we can to any certain number. The question often asked is, how close to the actual number can we get? If we can get close that number that would be considered accuracy. When we think about precision, it is a different concept. Once we have been as accurate as we can be with our measurement, precision would be how many times we can achieve that measurement. Can it be duplicated? Society Dependence on Accuracy and Precision When we think about all of products available in the open market, we, as consumers, expect consistency in the products we buy on a regular basis. For example, Diet Coke is product a lot of us love to consume on a regular basis. We expect that soft drink to have a certain taste and not be flat. If we were to buy......

...Chemistry in Life and Society Chemistry in Life and Society Chemistry is an important aspect of life and everything involved in it. From the precise measurements used in baking cookies and cakes to the cleaning agents used to clean the windows your little one smudges their fingers all over! Precise measuring when baking is essential. If one puts too much of one chemical it can throw the whole dish off and make it inedible. Many foods are also flavored with artificial flavoring and those are also chemicals as well. Chemicals affect the daily lives of everyone although some do not even realize it. Society depends on the accuracy and precision of measurements in many different areas. From filling up at the gas station to buying a gallon of milk. In everyday life accuracy and precision are usually thought of as interchangeable, but these two terms have crucial differences. Precision is a group of measurements that are close to each other, but they are not necessarily accurate. Accuracy of a measurement is how close the measured value is to the accepted value. In science “scientific numbers are reported so that every digit is certain except the last, which is estimated” (Tro, 2009, pg.14). Accuracy and precision is presented daily in life. When people play darts depending on which game they are playing one wants to be precise. With each throw of a dart one gains points for the precision in where the dart lands. People often rely on the accuracy of......

...Chemistry and Society CHM/110 Chemistry Is Everywhere Humans are surrounded by chemistry. Every product one uses on a daily basis is linked in some way shape or form to chemistry. Food, clothes, electronics, vehicles and medicines are all made up of molecules of elements. Through chemistry these elements were combined to form alloys, plastics, fabrics, liquids and gases that make up these products. Chemistry, like other sciences, relies on accuracy and precision in order to remain a reliable source of knowledge and a means for advancement of various aspects of human life. This paper will discuss the importance of accuracy, precision and the scientific method in chemistry and how these affect the lives of the average humans. Accuracy and Precision Accuracy and precision are paramount in the realm of chemistry but it is important to note that even though these two things are related they are different. According to Merriam-Webster (2012), accuracy is the degree of conformity of measure to a standard or true value. For example, if one is taking a drive that is known to be 5 miles and their GPS reflects a distance 4.9 miles travel the GPS is accurate to within one tenth of a mile. While accuracy and precision reflect how close a measurement is to a standard or true value, precision differs in that it is a reflection on how reproducible these measurements are. For example, if the same GPS from above measures 4.9 miles each time for 5 separate time then it is a......

...Chemistry and Society Accuracy and precision are two critical factors to contemplate when performing a measurements of data. Both accuracy and precision indicate how a measurement is close to a definite value. Accuracy reflects how close a measurement is to an identified assessment or accepted value while precision produces how measurements are recalled, even if they are distant from the accepted value. (Helmenstine, 2014) Precision also refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the agreement between experimental data and a known value. (Helmenstine, 2014) Chemistry and Society Accuracy and precision are important conceptions, and how they relate to an experimental measurement. By using scientific notation the concepts of precision and accuracy can be accomplished in a simpler matter. Precision and accuracy can be in hitting a bulls-eye of a target. If you hit the target accurately implies you are close to the center of the target even when the marks are on different sides of the center of the bulls-eye. If you hit the target precisely means all the hits you made are spaced closely, but still far from the center of the bulls-eye. (Helmenstine, 2014) Our society is depending on the precision and accuracy when measuring products we purchase every day. Precision and accuracy goes hand in hand together to make proficient measurements. If a product is not measured correctly, it would not have the same......

...ARTICLE 1: COMMUNITY MUSIC LESSONS IMPROVE MINDS OF DISADVANTAGED KIDS SUMMARY This article is written by Shereen Lehman. It was about music lessons can improve the minds of children. Community based music lessons for disadvantaged youth can have positive biological effects on their brains. The children were actively playing instruments themselves rather than passively listening to others’ music. In this article, it explained that the children between the ages six and nine participated in the study published in the Journal of Neuroscience. They all went to public schools and lived in gang-reduction zones of Los Angeles. The children were split it into two groups. One group started lessons right away. For two hours per week, they received training in music fundamentals and learning to play the recorder. Most kids progressed to group instruction with instruments after six months. The second group waited a year before starting lessons. Each year the research team evaluated the children’s ability to process speech. Children who took lessons for two years showed improvements in their ability to distinguish similar sounds. However, these changes were not apparent after only one year. The music deeply engages the emotional system of the brain and children learn best when they’re excited about things. COMMENT Music is an art form whose medium is sound. It is about melody and harmony. Music is something that known as universal language. Regardless of where are you from......

...Chemistry and Society Accuracy and precision are used for measurements. The term accuracy means to have the exact value. The term precision means to be comprehensive and exact. The accuracy of a value is the measure of how closely the results agree with a true or accepted value.   Precision of a value is the measurement of the reliability of the experiment. The differences are within the definitions, it all depends on what you are looking for within the results of a test for the proper use of these two units of measurements.     Society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, a bushel of corn, or a liter of bottled water. These measurements have to be precise and accurate when it this relates to how farmers sell their products such as wheat, corn, milk, peanuts, and cotton, by weight and or in a bulk sale. Like food products gasoline, water, oil, and several other liquid goods are sold in quantity and if the measurements are not accurately sold per gallon then the United States government will not retain a profit from the barrel of gasoline, water, oil, and several other liquid goods that are purchased from other countries. I would have to say that this really is about supply and demand and the ability to generate a profit from the accuracy and precision of the weight and how much to sell an item for in most situations. Other ways society depends on the accuracy and precision of......

...Summary of “A Cell-Based Systems Biology Assessment of Human Blood to Monitor Immune Responses after Influenza Vaccination The goal of this study was to create methods and define protocols that may be used in future systems vaccinology studies. Having these tools at the ready can lend a hand in investigating the various reactions of different cell types to the immune response generated after vaccination. Scientists used influenza vaccinations in this study. Among the questions addressed the most important was if it was possible to develop these protocols and methods to study immune response to vaccinations in various individuals. One question addressed was how to “investigate the contribution of individual cell types to the immune response after vaccination.” (Hoek) Another question was is there any changes in protein-coding or non-coding RNA transcripts after vaccination. To answer their questions, the scientists established an efficient way to purify human T and B cells, natural killer (NK) cells, myeloid dendritic cells, monocytes and neutrophils from venous blood. Having this method not only helps conclude a hypothesis, but can be used in the future to help other scientists conduct their experiment. Using this high dimensional molecular approach, scientists can use systems biology to identify changes in the blood caused by vaccinations or other perturbations. Their results reveal that RNA and protein expression profiles from each individual sorted cell type differ......

...Chemistry and Society Chemistry is in everything from a single element to complex compounds. It affects most every aspect of life in a person life and in society. Chemistry is involve with the medicine that a person take, the gas that they put in the tank of their car, the clothes that they put on for work, and to the food that they put in for nutrition. However, how does all that work to the betterment for them is due to the accuracy and precision of the measurement that chemist have come to find. The definition per the dictionary.com for accuracy is “the condition or quality of being true, correct, or exact: freedom from error or defect” (Dictionary.com, 2011). In addition the word precision can be interchangeable with the word accuracy so when a chemist is formulating a new compound they use measurement that is precise and accurate. However the difference between the two words is that accuracy is that getting close to the actual answer whereas precision is getting the same result every time and that it is reproducible and getting the same answer each time (Rutledge, 2010). Chemist use measurement everyday when they are working to find new stuff but even the everyday person uses these same measurements to do everyday work. Three types of measurement that a person might use are length, weight, and volume. In today society a carpenter might use all three from cutting the material, weighing out load limits, and the volume of a pool that they are installing. Most people......

...Running head: UNV-501: ARTICLE SUMMARY UNV-501: Article Summary Melissa Osborne Grand Canyon University Title: UNV-5: Article Summary This article titled “Read-only participants: a case for student communication in online classes” discussed the importance of communication in online courses as well as the reasons why students succeed or fail in these online courses. To obtain answers to the concerns previously listed, an 8 week study of students in an online class was conducted. This study consisted of monitoring online communication and classroom activity among students with different backgrounds with geographical location and age being two of the main contributing factors. From this study, results of both success and failure were discovered and documented. From the aspect of success, the following results were found: First, classes that had online discussion helped students that would normally be introverts in a traditional class, to be active in discussions. Second, this type of class helped to improve the learning of students by creating questions and answers (in the form of posts) of high critical thinking skills. Third, online discussions that were developed created a community of support and healthy interaction (L. Nagel, et al., 2007). Fourth, the facilitator (professor) that was very interactive with his class became a great asset to the online class because he provided feedback and affirmations to the students through posted replies.
