Final answer:
Science is the systematic study of the natural world through observation and experiment, comprising both a body of knowledge and a process for gaining further insights. It's based on empirical evidence and logical reasoning, and covers various disciplines, from physics to biology.
Step-by-step explanation:
Science is the knowledge about or study of the natural world based on facts learned through experiments and observation. It encompasses a systematic approach to gathering information about the universe by observing, testing, and generating models that explain our observations. Science is both a body of knowledge and a process of acquiring further understanding of natural or human-made phenomena. This discipline relies heavily on empirical evidence and logical reasoning, acknowledging that scientific theories and laws must stand up to rigorous testing against the natural world. In fields such as physics, chemistry, biology, and environmental science, scientific investigation entails planning for questions and testing possible answers with evidence and logic. The scientific method is fundamental to science, requiring that hypotheses be carefully scrutinized against natural observations and that conclusions be open to revision in light of new evidence. Science is not only a quest for practical applications, such as in medicine and engineering, but it is also driven by curiosity and the pursuit of knowledge for its own sake.
