For this purpose, a proposal was presented to help chemistry teachers to provide students with a better understanding of more meaningful learning. The Teaching of Chemistry in Basic Education presents several challenges regarding the introduction of concepts related to the structure of matter. The approach of this project is centered in the interaction between the Astronomy and the Teaching of Chemistry, in an interdisciplinary perspective with focus in the course of didactic engineering. It is premised that this approach may attract the interest of high school students. The methodology was developed in the classrooms of the Luiz Eduardo Magalh?es College in Feira de Santana-BA. The use of a learning sequence, centered on experimental and observational phenomena where the student's performance is intensified by the possibility of self-regulation and confrontation with the proposed situations, enabled an evolution of strategies, enhancing students' cognition. In an enveloping and structured way in its four phases, the course of didactic engineering contributed to progress in improving teaching and learning, since the agreed proposal was executed and indicates that it is possible to favor the learning of concepts of Teaching Chemistry with emphasis to topics, motivating Students to learn / O principal objetivo deste trabalho foi descrever os conceitos de Modelos At?micos, dentro do cen?rio do ensino de rea??es qu?micas, relacionando-os empiricamente com os processos de luminesc?ncia qu?mica e contextualizados com o fen?meno das Auroras planet?rias. Para o efeito, foi apresentada uma proposta para ajudar os professores de qu?mica a oferecer aos alunos uma melhor compreens?o da aprendizagem mais significativa. O Ensino de Qu?mica na Educa??o B?sica apresenta v?rios desafios em rela??o ? introdu??o de conceitos relacionados ? estrutura da mat?ria. A abordagem deste projeto est? centrada na intera??o entre a Astronomia e o Ensino de Qu?mica, em uma perspectiva interdisciplinar com foco no curso da engenharia did?tica. Pretende-se que esta abordagem possa atrair o interesse dos alunos do ensino m?dio. A metodologia foi desenvolvida nas salas de aula do Col?gio Luiz Eduardo Magalh?es em Feira de Santana-BA. O uso de uma seq??ncia de aprendizagem, centrada em fen?menos experimentais e observacionais, onde o desempenho do aluno ? intensificado pela possibilidade de auto-regula??o e confronto com as situa??es propostas, permitiu uma evolu??o das estrat?gias, aprimorando a cogni??o dos estudantes. De forma envolvente e estruturada em suas quatro fases, o curso de engenharia did?tica contribuiu para o progresso na melhoria do ensino e da aprendizagem, uma vez que a proposta acordada foi executada e indica que ? poss?vel favorecer a aprendizagem de conceitos de Qu?mica de Ensino com ?nfase em t?picos, motivando esudantes para aprender
