microcosm
A small, representative system having analogies to a larger system in constitution, configuration, or development
Example:
A boarding school is a microcosm in comparison to the real world. Although it may have the same characteristics, it is just a smaller version of it and not the real thing. See macrocosm and wobblotocrosm
