Nature of science. Science, as defined by the National Academy of Sciences, is the "use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process. " This vast body of changing and increasing knowledge is described by physical, mathematical, and conceptual models.
