After the identification of the problem and delimitation of the content related to Atomic Radius, a game activity and an educational game about the respective subject were made and applied to students of the 1st grade of a public secondary school. Data were collected using qualitative methods, such as: questionnaires, participant observation and humor maps, which aided the analysis of the results. Through the activities developed, one can see how educational games are important for the teaching and learning processes, because they place the students in a position of protagonists of the construction of their own knowledge, which usually does not occur in didactic games or in traditional classes, marked by the passivity of the students.porAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Jogo educativoAtividade lúdicaPesquisa-açãoEnsino e aprendizagemEducational gameGame activityAction-researchTeaching and learningArtigo10.21577/0104-8899.20160149
