This essay presents a proposal for an experiment directed to the teaching of chemistry, using two free code software, Scratch and Tracker. Through this software we will perform the analysis and simulation of the quantities related to the phenomenon that describes the intermolecular interactions present in the analyzed substances. In the development of this proposal, both simulation and experimental, it was decided to describe only the dipole-dipole and hydrogen bond interactions, present in the analyzed substances (water, acetone and alcohol). By means of these observations, data were obtained in the form of graphs, which describe the rates of volume variations of the substances, with the increase of the temperature, verifying what is described in the specific literature, about the intermolecular forces, as well as, the use of Scratch as an analogous way of simulating the phenomenon, showed potential to explore a perspective beyond the macro and micro fields that involve the behavior of the particles of a substance, through an animated simulation. The proposal is simple, possible to be developed in a school environment, with small considerations in its execution, however, these do not present potential to disturb the idea and purpose of this proposal, both to explore the mathematical foundation that underlies the analysis of the videos, as well as, can consolidate and strengthen the numerous ideas that arise to assist in the teaching-learning process, which can make use of Scratch as a learning object, as a means to enable the didactic transposition.
