A scientific theory can be said to mean a set of statements that are developed through a process of continued abstractions. These theories are aimed at a generalized statement usually used in explaining a phenomenon. A theory is quite concerned about the truth, much more than being understood. They are not expected to be stories
A model, on the other hand, is a purposeful representation of reality. They provide a local understanding of any given phenomenon. Models are more particular about being understood, rather than the truth
