The scientific competences point to the development of capabilities, abilities and aptitudes which help to solve problems according to the context where the facts take place. Referring to PISA, 2015 there are six levels of performance to develop scientific competences. The main purpose here is to make students identify, explain, and put into practice the scientific knowledge consciously, as well as the knowledge about Science in a great range of possibilities, somehow complex or easy circumstances. Besides they use this knowledge, they can also be able to use arguments and apply some recommendations to take logical decisions. At the same time, they could show abilities to solve some daily problems analyzing, comparing and making relations among different difficult situations related to composition, isomery and structures of chemical compounds.
In this paper a proposal is made for teaching Chemistry through classes designed to learn the spatial structures, nomenclature and isomery of organic compounds. Some workshops are planned to represent the chemical compounds (formulae) and their spatial structures. The most important is the opportunity the students have to manipulate spatial structures in 3D.
Also, the way how the workshops are designed help the students to visualize the structures and make a difference between it and the one the books show. It is sure that the manner how students get this knowledge to develop scientific competences in better than in our public schools.
