You should consider supplementing your major with classes from disciplines where you might like to apply you biology background, such as chemistry, environmental science, engineering, or business. Opportunities in teaching exist at both the high school and college levels. If you are interested in high school teaching, you will need to gain certification in secondary biology. At the college level, a Ph.D. is usually required. Many college and university teachers also conduct school-related or independent research.
Opportunities also exist in zoos, wildlife parks, and museums as educators.
Many opportunities for biology majors exist in the area of research. Research assistants generally work closely with biologists in all areas to assist them with laboratory experiments. A bachelor's degree will be the basic requirement for gathering, recording, and analyzing data as well as working with a variety of research equipment. Positions in research are available in a variety of settings, including health care, biotechnology, and higher education. If you are interested in basic research, which deals with uncovering what is not known, or applied research, which encompasses translating basic research into practical uses, then an advanced degree will be required.
