"Scientists often say, 'Science is the process of making and testing models of the world.' We begin by observing the world to identify patterns in natural events. We then work to produce testable hypotheses or models to explain these patterns. We test these models by gathering further data, and use our data to revise our models, creating an iterative process."
"In science, a law is a general term for a mathematical description of some aspect of nature. It is consistent with all experiments that have been performed to date, and has a range of applicability. A theory is a testable explanation for patterns in nature."
