The Scientific Method
The scientific method is a procedure that can be used to investigate a phenomena or correcting previous knowledge. It is defined as "a method or procedure that has characterised natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypothesis." by the Oxford dictionary.
The scientific method is an ongoing process, which usually begins with observations about the natural world. It then becomes a hypothesis and an experiment is soon carried out to determine the conclusion. We can then refine, alter or reject the conclusion. If rejected, the scientist usually goes back to making more prediction of what is going to happen.
