Final answer:
Science is the branch of knowledge that encompasses the systematic study of the physical world through observation and experimentation. It employs scientific methods to construct and test theories and laws about natural phenomena, as exemplified by disciplines like biology and physics.
Step-by-step explanation:
The branch of knowledge that deals with a body of facts or truths obtained by direct observation, experimental investigation, and methodical study, all systematically arranged to show the operation of general laws, is science. Science is the study or knowledge of how the physical world operates, based on objective evidence determined through observation and experimentation. This includes formulating and testing hypotheses, laws, and theories.
Scientific methods are techniques and processes used in constructing and testing scientific hypotheses, laws, and theories, and in deciding issues on the basis of experiment and observation. The application of the scientific method plays an integral role in the sciences, including disciplines like biology and physics, as it is a distinctive way of gaining knowledge about the natural world, striving to answer questions with evidence and logic.
Science is a systematic pursuit of knowledge, involving the empirical way of knowing through senses and verification by repeated experimentation and observation. It goes beyond memorization of facts, encompassing theories and laws that describe the very fabric of the natural world and its phenomena.
