Final answer:
Scientific knowledge refers to facts derived from the scientific method, a systematic process involving observation, hypothesis testing, and use of deductive and inductive reasoning.
Step-by-step explanation:
According to the text, scientific knowledge is best defined as known facts about a particular subject derived from the scientific method. This involves a systematic process of observation, formulating a hypothesis, refining that hypothesis through careful observation and testing, and ultimately confirming or falsifying it. The scientific method also includes deductive and inductive reasoning, allowing for a circular progression of knowledge; theories and hypotheses are tested against real-world empirical observations, which in turn lead to further insights.
