In this paper, from the experiences of the Collective Ciata, we seek to elucidate theoreticalmethodological aspects that can establish the teaching of Chemistry for education for ethnic-racial relations and the implementation of law 10.639/2003. This research was based on the research-action technique. The recording of the interventions was done followed by transcription and analysis according to the theoretical reference of the analysis of the conversation. Our results show that racism is present in the classroom, therefore, also in Chemistry class. The teacher deals with the real school and must be trained to act in it. It is possible to promote curricular changes in favor of black populations by designing a curriculum that contemplates the ethnic-racial diversity of Brazilian society. Our results showed that it is possible to discuss in a Chemistry class subjects related to the proposals of the mentioned law, as well as, to approach concepts of related chemistry. For this purpose, knowledge was mobilized that were not present in the curriculum of the degree in Chemistry and, therefore, demanded training in service through the group of studies instituted by the Collective Ciata.
