Step-by-step explanation:
A scientific method can be described as a method on the basis of which all scientific theories or researches are made. A scientific method begins with a question. A hypothesis is made in response to the question. To test the hypothesis, experimentation is done. And finally a hypothesis is considered true or false on the basis of experiments made.
