This work discusses the approximation of students and teachers of Basic Education - Elementary School (final years) and High School with Environmental Engineering. It uses a practical methodology that includes wetland systems built for wastewater treatment, didactically presented in this study with the treatment of synthetic methylene blue effluent for public school laboratories, based on prototypes. The experimental units reproduce wetland systems, which constitute biological, physical and chemical processes existing in naturally flooded environments. The experimental approach of Environmental Engineering in the school context gives students and teachers the opportunity to use adaptable practicable practices to solve real problems in the environment in which they live, in order to make it functional and accessible on a daily basis. Teachers, in contact with the same approach, can expand the methodological alternatives aimed at their pedagogical practice. The methodology used in this study combines bibliographic research with applied research, with experimentation that shows positive results for the treatment of effluents from wetland systems. The entire construction process of the experimental units favors the admission of Environmental Engineering as a solution for situations that involve care for the environment. It is about providing Basic Education students and teachers a broad view of the potentialities, functionalities and possibilities that come from Environmental Engineering applied in everyday life. The construction of the prototypes, made in the laboratory using the rice plant from the waters, enabled the test of the treatment of the synthetic methylene blue effluent. Positive results were achieved regarding the visualization of the partial removal of the dye in the treated samples. The use of the school environment for the development of this study also allows both students and teachers to act as multipliers of the knowledge acquired throughout the process, whose results elucidate affordable, low-cost and sustainable solutions as a possibility for water treatment.
