Why do scientists need to know whether their behaviour are be acceptable to morality ?I believe that science means the research is for truth, such as a quest for objective knowledge about nature; it is social institution means serving society's needs and improving people's lives as well as it made up of people with human needs and desire; and it is a profession, involving training, standards, a career, respect and privilege. Whether where is science done? Science is done at universities, in government, laboratories or government funding, in military laboratories or with military funding, industry laboratories or with industry funding. Scientists need to know different standards and goals apply to organizations under different circumstances. University goal is to advance knowledge to educate students to serve the public, government goal is to protect the nation's people and property to compete and cooperate with other nations to keep global security and to serve the companies or general industry, and increase opportunities in the global market. Hence, when any scientist works in different organization, then the organization will has different goal and the scientist will have the different goal and different scientific morality or ethic in different situation. Science include Astronomy, Biology, Botany, Computer science, Chemistry, Cosmology, Geography, Geology, Jurisprudence, Mathematics, Paleontology, Physics, Economics and others etc. different scientific researches. A scientist is a person engaging in a systematic activity to acquire knowledge that describes and predicts the natural world. In a more restricted sense, a scientist may refer to an individual who uses the scientific method. The person may be an expert in one or more areas of science. Also scientists perform research toward a more comprehensive understanding of nature, including physical, mathematical and social realms. Hence, Scientists are also distinct from engineers, those who design, build, and maintain devices for particular situations; however, no engineer attains that title without significant study of science and the scientific method. When science is done with a goal toward practical utility, it is called applied science. An applied scientist may not be designing something in particular, but rather is conducting research with the aim of developing new technologies and practical methods. When science is done with an inclusion of intangible aspects of reality it is called natural philosophy.

Besides, Science and technology have continually modified human existence through the engineering process. As a profession the scientist of today is widely recognized. Scientists include theoreticians who mainly develop new models to explain existing data and predict new results, and experimentalists who mainly test models by making measurements - though in practice the division between these activities is not clear-cut, and many scientists perform both tasks. However, scientists can be motivated in several ways. Many have a desire to understand why the world is as we see it and how it came to be. They exhibit a strong curiosity about reality. Other motivations are recognition by their peers and prestige, or the desire to apply scientific knowledge for the benefit of people's health, the nations, the world, nature or industries (academic scientist and industrial scientist).
