All natural objects, events, and processes, are connected to each other in such a way that only a relatively few concepts are needed to make sense of them. Science concepts are manifested in daily life.
Science is directed towards a progressively greater understanding of the natural world.
Science develops rational decision making skills applicable to major issues of personal and public concern. A system is a collection of things and processes and the interactions among them. A system can include processes as well as things. Thinking about things as systems means looking for how every part relates to others. Such feedback can serve to control what goes on in the system as a whole.
