A hypothesis is formed as an explanation to a phenomenon. Experiments are then designed to test the hypothesis and these tests must be able to be repeated to better predict future results. The goal in the scientific method is to come up with a scientific theory that can explain the phenomenon that will stand up to the study of experts in whatever field of science the theory addresses.
Another goal and reason for using the scientific method is to be as objective as possible and reduce any bias that may exist in experiments and in interpreting results. In the process of using the scientific method, all activities should be documented, archived, and be made available to be shared with other scientists so all results can be verified and all experiments involved can be duplicated to ensure reliability.
The scientific method has led to the discovery of some of the most important concepts in science today such as evolution, gravitational theory, relativity, and too much more to list. It helps to catch frauds and bring the truth to light. It continues to be the standard for which all scientific discoveries are measured and verified and it has stood the test of time to be used in all fields in science and it has applications in many other industries.
