In order to provide a more comprehensive understanding of the subject, it is important to present it through activities integrated into the students’ context. Therefore, the objective of this study is to analyze the contribution of a methodological proposal integrated into Physics teaching and structured as a Didactic Sequence with interdisciplinary aspects on the theme of food irradiation in the Amazonian context, with regard to the development of Scientific Literacy among New High School students from a public school in Manaus, Amazonas, Brazil. This is a qualitative research study of an applied nature. The approach is characterized as Action Research, and the instruments used for data construction include the activities developed throughout the proposal, such as questionnaires, a timeline, a photographic display line, mind maps, and written productions. Data analysis was carried out from the perspective of content analysis, focusing on indicators of Scientific Literacy. The data are analyzed and discussed based on students’ interactions and reflections, highlighting conceptual advances and changes in perception regarding food irradiation. The discussions indicate that, initially, students presented misconceptions related to the topic; however, throughout the activities, these concepts were gradually reframed based on scientific evidence and knowledge exchange during the classes. Furthermore, the debates promoted during the stages of the research pointed to greater student engagement when the topic was contextualized with local examples and everyday situations. The activities presented show that participants came to understand the technique as a safe and efficient technology for food preservation. As a result of this research, an Educational Product was developed in the form of an instructional teaching guide aimed at contributing to the development of strategies integrated into Physics teaching on ionizing radiation as a food preservation technique, especially within the Amazonian scenario. This guide may be used by high school students, mediated by basic education teachers in the field of Natural Sciences and their Technologies. The results show that the objectives proposed in this research were achieved and may contribute to the construction of scientific knowledge about food irradiation in the Amazonian context and to the target audience for which it is intended.PPGEECA - Estratégias educativas para o ensino de ciências naturais na Amazônia
