Biological scientists study the living world and how it works.
Through careful medical research, analysis and studies, they examine plants, animals and humans and their relationship to the environment. You must complete high school or your GED and pass certain college-preparatory classes, including English, math and science. To be eligible for entry-level jobs, such as that of a staff research associate or a biological technician, you must finish at least four years of college. To be eligible to teach at the college level, perform independent research or work in an advanced position in a research organization, you should complete three to five years of school in a PhD program after getting your bachelor s degree. As a biological scientist, you will divide your time between working outside in the native environment of the plant or animal you are studying and in a research laboratory.
