Molecules can be studied as isolated species, in small groups, or as vast assemblies. The modes of thought range from the highly quantitative methods of the physical chemist to the more pictorial and intuitive thinking of the synthetic chemist. There are niches in chemistry for many types of people. Chemists are also widely employed in the health industry, in hospitals, in research institutions, in drug companies, and in the food and agriculture industry. Environmental chemistry is rapidly growing.
Teaching is another option.
A bachelor's degree plus appropriate education li censure are required for high school teaching. Junior college and university teaching requires an advanced degree, usually a Ph.D. Graduate training in chemistry, ordinarily the Ph.D. is required to become a research scientist in industry or in a college or university. The Ph.D., which can be obtained after about three years of graduate study, signifies that the holder is trained in research and in designing projects to answer fundamental questions. Those interested in pursuing a research career should seriously consider graduate school. A degree in chemistry need not limit one to becoming a chemist in the traditional sense.
