Resumo
Las ferias de Ciencias son comúnmente realizadas en escuelas de enseñanza básica buscando inser tar a los estudiantes en una perspectiva didáctica más activa. En 2017, el Centro de Ensino e Pesquisa Aplicada à Educação, escuela vinculada a la Universidad Federal de Goiás, realizó su primera Feria de Ciencias. En la disciplina de Ciencias, el trabajo desarrollado con las clases de 9º año dirigió la realización de experimentos al establecimiento de relaciones entre la problemática ambiental y las cuestiones de Ciencia, Tecnología y Sociedad. Para el contexto investigativo de ese movimiento, se utilizó el estudio de caso y, como instrumento de recolección de datos, fueron utilizadas la observación participante del profesor / investigadora, el registro en diario de campo y registros fotográficos. Para este artículo, se analizaron las presentaciones de cuatro grupos que presentaron experimentos con foco en producción de energía, reciclaje e impactos ambientales generados por la producción de bienes de consumo. En la perspectiva de la enseñanza y el aprendizaje, se evidenció el compromiso de los alumnos, tanto comportamental como emocional y cognitivo, además de obser var la estructuración de un proceso de significación a par tir de las etapas de planificación, organización y realización de los experimentos. Considerando el análisis realizado, se concluye que las Ferias de Ciencias se configuran como posibilidades didácticas interesantes para la discusión y reflexión sobre el papel del ser humano como agente de interferencia en el equilibrio ambiental, teniendo como recorte el desarrollo de las tecnologías disponibles en la sociedad actual.

For the article, we focused on the presentations of four groups that presented experiments focused on energy production, recycling and environmental impacts generated by the production of consumer goods. In the teaching and learning perspective, students’ engagement, both behavioral and emotional and cognitive, was evidenced, as well as the structuring of a meaning process from the planning, organization and realization stages of the experiments. Considering the analysis carried out, it is possible that the Science Fairs are presented as interesting didactic possibilities for the discussion and reflection on the role of the human being as an agent of interference in the environmental balance, taking as a cut the development of the technologies available in the current society.
