The scientific method is an idealized process of inquiry.

Experiments must be designed to test groups and experimental groups in a way that cancels the effects of unwanted variables. Researchers usually cannot control all factors in an experiment.

Science can be distinguished from other styles of inquiry by. A dependence on observations and measurements that others can verify. The requirement that ideas (hypotheses and theories) are testable by observations and experiments that others can repeat. Scientific hypotheses are falsifiable, but often difficult or impossible to prove true.

Is broad in scope: generates new hypotheses. Is supported by a large body of evidence. Is constantly being challenged, tested, and modified as new information is obtained: science does not set out to prove theories or hypotheses.
