What makes a school a closed system?

A school can be considered a closed system when it operates independently and does not interact with its external environment in a significant way. In a closed system, resources, information, and energy are self-contained within the school and do not flow in or out from external sources. This means that the school's activities, policies, and decisions are made internally without much influence from outside factors. Additionally, a closed system school may have limited collaboration with other schools, organizations, or community members, further isolating itself from external influences.

A closed system is one that does not exchange matter with its surroundings, and in which energy is not transferred outside the system or inside the system.

A school is not a closed system because:

- Matter: Students, teachers, and other staff members enter and leave the school on a regular basis. In addition, materials and supplies are brought into and out of the school.
- Energy: Energy is used to heat and cool the school, to light the classrooms, and to power the computers and other equipment. This energy comes from outside the school, and it is not recycled within the school.
