Discussion with Kara Rogers of how the scientific model is used to test a hypothesis or represent a theory



Transcript

A scientific hypothesis is an idea that proposes a tentative explanation for a phenomenon that's been observed. It is both falsifiable and testable. Falsifiability is evident in the if/then statement of the hypothesis, and its testability is evident in its ability to be supported or refuted by scientific observation or experimentation. A scientific theory differs because it's a broad general explanation that incorporates usually multiple hypotheses or multiple observations.

Scientific model is used to test the scientific hypothesis or to provide a representation of a scientific theory. In the case of plate tectonics, scientists came up with a hypothesis, an idea that Earth's crust was divided into plates that can move or shift. And then models were developed to simulate, or represent, the plates on Earth's crust. And then as more evidence was incorporated, the theory of plate tectonics was developed.
