The way as Chemistry is boarded in the schools can contribute for the misconceptions, a time that the concepts are presented of form purely theoretician (and, therefore, tedious for the majority of the pupils), as something that must be memorize and that it is not apply the different aspects of the daily life. So, the aim of this work is to provide the understanding of the chemical world that underlies everything around us by introducing basic chemical concepts and their everyday applications. So that, some specific topics will be presented and they were selected according to their relevance and their ability to be presented in lessons on molecular modeling. This strategy is based on the use of images and free graphics programs employed in chemistry successfully, as the visual effects help the students to “see” abstract descriptions in a concrete form. According to the results obtained by using this methodology, we can conclude that the use of images and computational techniques help the presentation of scientific topics and motivate and facilitate the "chemistry communication".
