Answer:
The quest to understand and explain the natural events has to lead the scientist to devise a scientific method.
A scientific method is a systematic approach to understand and explain any natural phenomenon. It plays important role in the scientific investigation as it acts as a gateway to answer and understand any event in depth.
A scientific investigation depends on making an observation and background research based on which a scientific question is asked.
If the question is asked about the event which has not been observed than different descriptive methodology without the formation of the hypothesis will be used.
