The Importance Of Science In Science

...Our project specifically focused on the DNA sequence analysis of the genes in duckweed and how those genes fit into bioremediation. As an intimidated and shy freshman with a strong yearning to be part of the science community at my school, decided to join the intensive program with barely any knowledge about biology. It didn't seem like a smart move at the time, but I'm glad that I had persistence because I learned so much about the field through the guidance from the team. Exploring PCR and Restriction Digests, my group and I were able to publish new proteins on the national GenBank. I learned more about biology and how to work/perform in a team. This motivated me to join the Science/Biology Olympiads where we do independent research and come together as a team to compete. I found that these opportunities along with the research in my science classes not only help me learn actual science but provide me with valuable life skills that will help in the...

Science

...The word 'science' is derived from the Latin word 'scientia' which means knowledge. Therefore, science is about gaining knowledge either through observing, studying, experience, or practice. Entire knowledge acquired through science is about discovering truths, finding facts, uncovering phenomenon hidden by the nature. Observations and experimentation, in science, support in describing truth and realities through systematic processes and procedures. For me, science is an intellectual set of activities designed to uncover information about anything related to this world in which we live. The information gathered is organized through scientific methods to form eloquent patterns. In my opinion the primary objective of science is to gather information and to distinguish the order found between facts. What Science Means to Me as an Upcoming Scientist Science exposes several ideas along with significant themes so that I could test them independently and without any bias to arrive at solid conclusion. For this purpose exchange of data and materials is necessary. I am able to generate real and tangible facts supported by reliable evidence. Work of scientist is based on theoretical science. It means, in theoretical science, there is only a sign, just a hint on which discoveries could be made, facts could be found. While studying science I am always working for determining truth, based on my perceptions, judgment, observation, experience, and knowledge collected through several means...

Science

...Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding1. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions. (There are, of course, more definitions of science.) Consider some examples. An ecologist observing the territorial behaviors of bluebirds and a geologist examining the distribution of fossils in an outcrop are both scientists making observations in order to find patterns in natural phenomena. They just do it outdoors and thus entertain the general public with their behavior. An astrophysicist photographing distant galaxies and a climatologist sifting data from weather balloons similarly are also scientists making observations, but in more discrete settings. The examples above are observational science, but there is also experimental science. A chemist observing the rates of one chemical reaction at a variety of temperatures and a nuclear physicist recording the results of bombardment of a particular kind of matter with neutrons are both scientists performing experiments to see what consistent patterns emerge. A biologist observing the reaction of a particular tissue to various stimulants is likewise experimenting to find patterns of behavior. These folks usually do their work in labs and wear impressive...

...Chapter 132 - Science and Technology Section SCIENCE AND TECHNOLOGY Science and technology provide people with the knowledge and tools to understand and address many of the challenges. Students must be provided with opportunities to access, understand, and evaluate current information and tools related to science and technology if they are to be ready to live in a 21st century global society. The study of science and technology includes both processes and bodies of knowledge. Scientific processes are the ways scientists investigate and communicate about the natural world. The scientific body of knowledge includes concepts, principles, facts, laws, and theories about the way the world around us works. Technology includes the technological design process and the body of knowledge related to the study of tools and the effect of technology on society. Science and technology merge in the pursuit of knowledge and solutions to problems that require the application of scientific understanding and product design. Solving technological problems demands scientific knowledge while modern technologies make it possible to discover new scientific knowledge. In a world shaped by science and technology, it is important for students to learn how science and technology connect with the demands of society and the knowledge of all content areas. It is equally important that students are provided with learning experiences that integrate tools, knowledge, and processes of science and technology...

...1. Describe how fishing has changed at Apo Island, and the direct and indirect effects on people’s lives. Apo Island’s marine preserve allows fishing with hand-held lines, bamboo traps, large mesh nets, spear fishing without SCUBA gear, and hand netting. Fishing with dynamite, cyanide, trawling, and Muro-ami are forbidden. This has increased fish populations and made it easier to catch the fish needed to support a family. The healthy reef community now attracts ecotourists and provides jobs for islanders. 2. What are some basic assumptions of science? 3. Distinguish between a hypothesis and a theory. A hypothesis is the second step from the scientific method that forms an educated guess based off an observation. A theory is the information that was gathered to support the proof of an observation and confirms the hypothesis. 4. Describe the steps in the scientific method. 7. What’s the first step in critical thinking? The first step in critical thinking is 8. Distinguish between utilitarian conservation and biocentric preservation. Name two environmental leaders associated with each of these philosophies. Biocentric preservation emphasizes the fundamental right of living organisms to exist and to pursue their own good. While utilitarian conservation emphasized that resources should be used for the greater good for the greatest number for the longest time. Two environmental leaders associated with the biocentric preservation philosophy are John Muir...

...Blueprint to address Australia’s lack of science strategy unveiled Chief scientist makes series of recommendations to improve the country’s skills in science, technology, engineering and maths Australia’s chief scientist, Ian Chubb, has unveiled a blueprint to address Australia’s lack of a science strategy, with proposals aimed at improving skills, supporting research and linking scientific work to other countries. Chubb has made a series of recommendations to the federal government to increase focus on science, technology, engineering and maths skills. The strategy is partially aimed at addressing the declining number of students taking advanced maths in year 11 and 12, as well as the shortage of qualified maths and science teachers. Chubb said each primary school should have at least one specialist maths and science teacher, a policy currently used in South Australia and Victoria. This would be encouraged by improving incentives, including pay, for teachers. Other recommendations include supporting research potential, improving research collaboration with other countries and doing more to stress the importance of science to businesses and students. Chubb said: “We are the only OECD country without a science or technology strategy. Other countries have realised that such an approach is essential to remaining competitive in a world reliant on science and science-trained people. “Science is infrastructure and it is critical to our future. We must align our scientific effort...

...Advantage Science gives us safe food, free from harmful bacteria, in clean containers or hygienic tins. It also teaches us to eat properly, indicating a diet balanced in protein and carbohydrate and containing vitamins. The results is freedom from disease and prolonged life. In pre-scientific days, food was monotonous and sometimes dangerous; today it is safe and varied. It is varied because through improved sea, land and air transport food can now be freely imported and exported. Science has also improved clothing and made it more appropriate for climatic and working conditions. Man-made fibers and versatile spinning machines, today enable us to dress in clothes both comfortable and smart without being expensive. Home, school and office all bear witness to the progress and application of science. Nowadays, most homes possess electric lighting and cooking, but many also have washing machines, vacuum cleaners and kitchen appliances, all designed to increase comfort and cleanliness and reduce drudgery. Science produces the fan which cools the air, the machinery which makes the furniture and fabrics, and hundred and one other features for good living. The books and papers are at school, and again everything from the piece of chalk to the closed-circuit television of instruction are the direct or indirect results of scientific progress. Learning is therefore easier. And clerical work is made far more speedy and efficient by the office typewriter, quite apart from the hundreds of...

...One of the major shortcomings of science supposedly is a lack of communication between scientists and the general public. Many argue that too often, science is only presented in written academic journals that are not so easily obtained by the general public. This is discussed on a daily basis and was argued in the aftermath of the 2011 earthquake and tsunami in Japan, as well as in on-going debate about other scientific theories and ideas. However, people fail to realize a few things. One of the major things is that, in terms of an earthquake or tsunami, you simply cannot predict anything like that. You cannot blame scientists for not being able to predict an earthquake like a meteorologist can predict weather events. Scientists can study things like seismic activity and they can make assumptions as to what may happen should an earthquake of a high magnitude hit and cause something catastrophic like a tsunami. Yet, some fail to realize that some safety measures were taken, and even inspectors that visited the Fukushima Nuclear power plant asked Japanese authorities to increase safety measures further. According to a France24 news article written three months after the catastrophe, “A three-page summary was issued at the end of the 18-member team’s May 24-June 2 inspector mission to Japan. It said the country underestimated the threat from tsunamis to the Fukushima plant and urged sweeping changes to its regulatory system. Japanese authorities have been criticised for...

...In this essay I will focus on the events surrounding the regulation of Alar (diaminozide) up to and including 1985, as a case-study of knowledge and decision-making amidst uncertainty (418-19). I pick this time period in particular, because it is when the NRDC and other public interest groups began their campaign in protest against the EPA's decision to not ban Alar. My analysis of the events surrounding Alar will take shape around a critique of Michael Fumento's article "Environmental Hysteria: The Alar Scare," in which he paints the NRDC as "fanatics" launching a "smear campaign" not founded in any rational decision-making. This is an important argument to counter, because it has not only been taken up by many to condemn citizen-group action in the case of Alar, but to criticize their activities in many other regulatory processes. The chief framework used to devalue public action in these cases is the technocratic model, wherein it is believed that decisions can be best made by objective, rational experts acting based upon scientific knowledge. In this case, we can see a perfect example of when a decision was decided by scientific experts, in accordance with the technocratic model. Fumento and other supporters of the technocratic mode privilege the scientific knowledge of bodies such as the Scientific Advisory Panel in this case over other forms of knowledge. He denounces NRDC as fanatics based on his claim that they acted in spite of, and in contradiction to scientific...

...Scientific papers are for sharing your own original research work with other scientists or for reviewing the research conducted by others. As such, they are critical to the evolution of modern science, in which the work of one scientist builds upon that of others. To reach their goal, papers must aim to inform, not impress. They must be highly readable — that is, clear, accurate, and concise. They are more likely to be cited by other scientists if they are helpful rather than cryptic or self-centered. Scientific papers typically have two audiences: first, the referees, who help the journal editor decide whether a paper is suitable for publication; and second, the journal readers themselves, who may be more or less knowledgeable about the topic addressed in the paper. To be accepted by referees and cited by readers, papers must do more than simply present a chronological account of the research work. Rather, they must convince their audience that the research presented is important, valid, and relevant to other scientists in the same field. To this end, they must emphasize both the motivation for the work and the outcome of it, and they must include just enough evidence to establish the validity of this outcome. Papers that report experimental work are often structured chronologically in five sections: first, Introduction; then Materials and Methods, Results, and Discussion (together, these three sections make up the paper's body); and finally, Conclusion. The Introduction...
