Answer:

The steps that can be seen in this story are observation and the questioning phase, which can also be called elaboration of the problem.

Explanation:

The scientific method presents the phases called observation, questioning (or elaboration of the problem), elaboration of hypotheses, experimentation, analysis of the results and conclusion.
