The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:
1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.
