Question

it is necessary to spread the knowledge of scientific method.... make it complex sentence ​

Answer 1

It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions.

Answer 2

Explanation:

scientific theory is a structure (or systematic scheme), conceived by the human imagination, to explain regularities in empirical data[1].

A theory differs from a “scientific fact” or a “scientific law” in that a theory attempts to explain "why" or "how": a “fact” is a simple, basic observation, whereas a “law” is a statement (often a mathematical equation) about a relationship between facts. For example, Newton’s Law of Gravity is a mathematical equation that can be used to predict the attraction between bodies, but it is not a “theory” to explain how gravity works[2].

There is disagreement as to the precise use of the words “theory” and “hypothesis” in scientific terms. Some “scientific theories” are so extensively tested and widely accepted (such as the theory that the earth rotates around the sun) that they are considered to be “facts”, however a scientific theory can equally be a new explanation that has yet to achieve wide-spread acceptance. Some consider that a “scientific theory” starts as a “scientific hypothesis” until it has been extensively tested and achieved wide-spread acceptance. Others consider that a hypothesis is a “limited” explanation and a theory is an “in-depth” explanation of a phenomenon: therefore a hypothesis cannot evolve into a theory (however a theory can encapsulate one or more hypotheses)[3].
