Installation art is the use of sculptural materials to utilize a space for art. It can be used with any type of media and isn't confined to a specific space either public or small. 

Performance art is exactly what it sounds like: people acting, dancing, etc. in any place at any time! Performance art can be any situation that involves four basic elements: time, space, the performer's body and a relationship between performer and audience.
