Constructed wetlands are artificial systems that mimic the natural decontamination processes present in lake and marine wetlands. These systems play a key role in mitigating climate change by reducing the environmental impact on the receiving aquatic bodies of treated effluent. In the context of this educational innovation research, the objective is to enrich the learning experience of students through the construction of a laboratory-scale wetland. The wetland will have five sections, each designed with different types of substrates and plants, to address different aspects of water purification. Each team of students will be assigned a water sample for characterization and decontamination, choosing the most appropriate configuration within the wetland to obtain the best results. Students are expected to develop key technical skills, while becoming aware of the importance of water treatment and its environmental implications. Further studies will focus on the effective construction of the laboratory-scale wetland and on the students’ hands-on experience in designing and implementing practical water remediation solutions using this didactic approach.
