The present work aims at presenting a methodological approach for the electrochemistry content that connects the three levels of representation of chemical knowledge through the classic experiment of the Saline Drop. From this activity it tries to integrate the different levels of representation in order to help the student organize his ideas in a vision of totality, presenting and discussing the possible connections that are established among the different levels of representation.
