Since my childhood I have always had an interest in being a scientist. I will try to explain it to you.The word scientist is a general term, used to describe someone who researches and examines various aspects of the physical world in order to attain a better understanding of how things work and function. There are many specializations of 'scientist', and depending on which field of study one chooses to follow, the work can vary greatly. Each scientist, however, follows 'the scientific method', which is a strict set of rules that ensure all new discoveries are factual and not just speculation.A scientist always gathers and uses research and evidence, to make hypotheses and test them, to gain and share understanding and knowledge. It may be heard as something boring but even the idea of being a scientist makes me very excited. A scientist can study in so many fields so there are so many things that I can be as a scientist. There are some major fields of sciences which are Natural sciences, Engineering and technology, Medical and health science, Agricultural science, Social sciences. I personally love natural sciences more so I will be explaining this field of science. A scientist who studies in the natural sciences can study biology, chemistry, physics and earth science. Among the natural sciences my favorite is biology. Biological scientists study living organisms and their relationship to the environment. Biological scientists who work in applied research or product development apply knowledge gained through basic research to develop new drugs, treatments, and medical diagnostic tests; increase crop yields; and develop new biofuels. Biologists can work in laboratoires and make some experiments due to their research. Being a biologist attracts me so much but there is a difficult path to be one. Biologists must have a 4-year undergraduate degree, such as a Bachelor of Science in Biology, for entry-level research positions. A few classes that biologists may take are microbiology, anthropology, biochemistry and molecular biology. Most employers prefer biologists with a master's degree in biology or in any of the life sciences to work in applied research, product development, management or teaching at the high school level. I wish to conduct independent research or teach in a university setting, I must have a doctorate degree in biology or a closely related field which is a very difficult thing to do.
