A physical science technician assists with scientific research and projects, typically within various departments and agencies of the federal government. As a physical science technician, you may be employed by departments such as agriculture, interior, commerce, the navy or air force—and your duties may vary as widely as these departments. For example, you may work in astronomy, physics, chemistry, engineering, geology, or metallurgy (to name just a few). You help perform tests in labs or in the field, collect and analyze data, then use that data to help programs achieve their individual goals. You also inspect equipment and ensure the veracity of experiments.
