Documento orientativo para organização e execução de feiras de ciências com experimentos de baixo custo no ensino de física

Abstract

This paper presents the development of a guidance document aimed at organizing and conducting science fairs featuring low-cost experiments for physics education. The overall objective is to equip teachers and undergraduate students to host these events, seeking to overcome recurring challenges in the Brazilian educational landscape, such as inadequate school infrastructure and a scarcity of science laboratories. The methodology is based on applied research with a qualitative approach exploratory and descriptive in nature conducted through a literature review of official documents and academic publications. The results highlight that science fairs serve as an active learning methodology linking theory and practice, thereby fostering student agency and early engagement in scientific inquiry. The resulting product is a practical guide detailing planning stages (pre-event, event, and post-event), committee organization, scheduling suggestions, and accessible experiments using recyclable and everyday materials. It is concluded that the proposed document is an essential tool for supporting teaching practice, enabling the democratization of scientific knowledge even amidst financial and structural constraints.
