Model
A physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Scientific Law
Statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena.
Scientific Method
A method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
Standard
An object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
Technology
The application of scientific knowledge for practical purposes, especially in industry.
