Science is the field of study concerned with discovering and describing the world around us by observing and experimenting. Biology, chemistry, and physics are all branches of science. Science is an empirical field, that is, it develops a body of knowledge by observing things and performing experiments. The meticulous process of gathering and analyzing data is called the scientific method, and we sometimes use science to describe the knowledge we already have.
