The Crea-ciencia project aims at the social appropriation of scientific and technological knowledge and innovation in rural and urban areas of the department of Tolima - Colombia. In its development, the strategy of the creativity route is proposed, which deals with how the educational community, with the integration of agents of the territory, identify and understand a problem, whose solution corresponds to the design and development of technological artifacts. In this process, education in science and technology plays an important role, as it gives meaning to many competencies that are promoted from the Colombian curricular standards, for example, the topic of modeling and the comprehensive use of scientific knowledge. The proposal is framed in the perspective of teaching based on modeling; where it is essential that children and/or young people in the creativity teams build models, initially, explanatory about the problem that is conceptualized, represent through various semiotic registers their solution proposals and concretize them through the construction of initial models or artifacts. To this end, expert knowledge is used, such as electronics, mechanical physics, biochemistry, environmental sciences and technological knowledge. This paper presents the systematization of Three cases - artifacts - whose designs are realized in robots, electronic-mechanical processors and biochemical products. This paper details the scope and limits of this appropriation process via teaching and learning based on models.
