In this paper, our attention focused on the processes of understanding chemical bonding models. Specifically, our research focused on the production of senses on this content in a group of students from of elementary public school. A collaborative teaching environment was used, wherein our group worked jointly with the 9th grade teacher responsible for the classroom and students. Our project consisted of teaching science in the classroom using the reading of science textbooks. We encountered a dual challenge; teaching reading skills for comprehension as well as teaching the chemical bond models. For this, our intention was to give good lessons as efforts to teach to read science textbooks to learn about models of chemical bonds. We researched the/in chemical bonding study process - driven by reading the textbooks and building dialogics relationships and of otherness. We used four pillars in our methodology: a cultural-historical approach in relation of otherness; a methodological procedural path; a construct made by surplus of vision and by exotopia; planned mediation based on reading and writing skills related to the chemical bond models. Here, we present the results related to two units of our analysis, the creation of purposes for reading, and reading as an counter-words offer. We analyzed the students' writing in search of evidence of development of understanding. Additionally, we were constantly attentive to the senses produced by the readings in order to check the students' interpretative walk. Our findings confirmed the students initial understanding of the relationship that exists between models and the properties. Herein we share our lessons.
