The research area in Chemistry Teaching has been concerned, in recent years, with important discussions about principles and actions that are effective from the point of view of teaching and learning processes. In this context, the need for alternatives, resources and materials that support and/or expand the possibilities of promoting the construction of scientific knowledge in the classroom is emerging. Therefore, considering the above, the objective of this research was to build and validate an educational product, within the scope of a professional master's course, for the teaching of chemical contents from the theme Forensic Chemistry and playful-experimental approaches, to be intended for teachers of Basic Education. Therefore, the guiding problem of this research was: What contributions to Chemistry Teaching, in Basic Education, could bring a paraded book that deals with the theme Forensic Chemistry with playful-experimental approaches? Thus, in an attempt to answer it, the methodology adopted was that of a qualitative study of the case study type, whose course consisted of a division into six interdependent (and sometimes simultaneous) stages: i) exploratory phase, in which there was a bibliographic review about Forensic Chemistry, playfulness and experimentation for chemistry teaching, in addition to the theoretical, methodological and epistemological foundations for the construction of scientific knowledge; ii) elaboration of the research instruments, with the production of two types of self-administered questionnaires, proposal of lesson plan and semi-structured interview; iii) construction of a paraded book with the theme Forensic Chemistry for chemistry teaching from playful-experimental approaches; iv) application of the research instruments carried out with criminal experts from the Perícia Oficial e Identificação Técnica do Estado de Mato Grosso – POLITEC/MT (semi-structured interview, aiming to better understand the daily work of the expert work) and members of the Programa de Residência Pedagógica em Química of the Universidade Federal de Mato Grosso – UFMT (questionnaires and proposal of a lesson plan for evaluation of said paradidactic); v) analysis of research instruments according to the assumptions of Análise Textual Discursiva (ATD); and vi) postvalidation resignification of the paradedtic book, which allowed corrections and deepening of the contents and the proposed didactic-pedagogical activities. Finally, by the construction and validation of this paraded book, it was possible for teachers of Basic Education Chemistry a new educational product that favors, within its limits and its possibilities, the promotion of a more contextualized, playful, experimental teaching that enhances more significant learning, contributing to the construction of scientific knowledge in the classroom.
