Scientists use the scientific method to ensure their studies are reputable and valuable. This requires that they make observations and propose a hypothesis or series of hypotheses (untested ideas) to test a particular theory—a thoroughly tested idea). For instance, Wegener’s hypothesis of continental drift was backed by evidence and observations, but the evidence was controversial and Wegener couldn’t offer a persuasive explanation of how continents could actually move. So his hypothesis was generally rejected. New observations and evidence, such as the volcanic eruptions along mid-ocean ridges and the subduction of oceanic crust beneath trenches, explained the motion of Earth’s plates (rather than the continents themselves, as Wegener had hypothesized). Similarly, after several observations and testing, the Big Bang emerged as an explanation for the development of the universe.   Each of the following is either a hypothesis, theory or observation.
