Avaliação do sistema de aquaponia como laboratório prático de ciências no ensino fundamental

Abstract

Aquaponics is a system that has gained credibility by synergistically integrating aquaculture and hydroponic production and promoting water reuse and nutrient cycling. To assist the learning of elementary school students through a practical and multidisciplinary approach, activities were held in August and September 2019 in a municipal school located in the municipality of Pureza, RN, with the participation of 10 students. 4th and 5th grades. year.

Two workshops were held at the school, where the first had as its theme the operation of the system and its main components, below. environmental and health benefits of systems and the importance of parameter measurement in aquaponics. The second theme was the importance of organic foods, water reuse and sustainability in aquaponics. The results confirm the contribution of the aquaponic system to the expansion of students 'knowledge, the importance and intrinsic interdisciplinarity of the system and the positive change in students' behavior in teaching-learning moments. It is also concluded that the diversification of the classes through the use of the system motivated the students and made them interact, that the applied concepts related to sustainability and the environment were positively assimilated from the practice.
