Observation is the first phase of the scientific method. At this stage, facing some system or situation that occurs in nature, the scientist is driven by curiosity and need to seek ways to understand what causes it to happen. Thus, from observation, which can be with the naked eye or the use of instruments such as the microscope, the scientist begins to formulate questions.
