The learning difficulties of Natural Sciences still constitute a challenging field, where traditional and decontextualized pedagogic practices contribute to students’ demotivation. Practical activities contribute, in an attractive and meaningful approach, to the efficiency of the process of teaching and learning Sciences, estimulating observation and curiosity, providing better understanding of content and improvement on scientific learning. Addressing all these issues, the question this research intends to answer is: how can the construction of an Educational Wormery made out of reused materials help overcome the challenges listed above? Thus, our aim is to investigate the knowledge acquired by using Active Methodologies in Science Teaching. The research took place at a public school in the state of Alagoas among 33 students attending the third grade of High School. The results show that using the wormery benefits the acquiring of concepts related to Natural Sciences. Therefore, the activities developed with the educational wormery come out as efficient and dynamic, helping stimulate scientific knowledge among pupils and even the School’s community, in addition to contributing with interdisciplinarity and the socio-environmental awareness developed throughout this experience.
