Biosphere contamination is a current environmental and social issue that must be included in the school programme. It is essential that students recognise their responsibility, and be knowledgeable about the generation and reduction of environmental pollution. Dyes are usually used in school activities and discharged into household effluents, constituting potential toxic agents. To offer solutions to this problem, it was proposed to evaluate the ability of Lemna sp. plants to remove synthetic dyes. For this, activities that require accessible resources and minimum safety precautions were designed, which could be carried out by students at home in the virtual education modality imposed by the COVID-19 pandemic. The practical experience integrated theoretical-practical contents from different disciplines, achieving a true interdisciplinary dialogue. The use of Lemna sp. secured a fast and significant dye decolourisation, demonstrating the importance of biodiversity in the attenuation of environmental changes due to anthropogenic activities. This experience allowed us to arrive at an interdisciplinary, significant and situated learning experience through the implementation of the scientific method.
