Document Summary
Hypothesis: educated guess based upon observation (sometimes, only one observation) Can usually be supported or rejected through experimentation or more observation. Can be supported or rejected can"t be proven to be true. Scientific theory: summarizes a hypothesis (or group of hypotheses) that explain a set of observations, supported by repeated testing. Considered valid if there is no firm evidence to dispute it (can be supported or opposed_ If evidence accumulates to support a hypothesis, it becomes a theory. Both hypothesis and theories attempt to explain the why . At the time it is made, no exceptions will be found to that law. Describe certain scientific observations but do not explain why they are observed. Does not say why things happen but how they happen. Law of gravity predicts behaviour of an object affected by gravity, but not explain why the object will fall. Newton"s theory of universal gravitation is the why must be seen together for the complete theory.
