Some of the advantages of this is you get to have more control of the event that transpire as well as being able to study and observe said events closer. a Disadvantage would be that you're not able to the real thing as in what would actually happen naturally for example if you set up an aquarium it may have a negative affect on the fish or the fish may act a different way in the smaller space as it wouldn't be used to it.
Hope this help! :)
