Abstract
Have you ever imagined conducting laboratory-based experiments outside the school facilities? A challenge in the natural sciences has been reconciling the theoretical basis with their practical applications. That is why the purpose of this work is to present a didactic sequence that addresses the contamination of water bodies by plastics, based on four homemade experiments: density of liquids, calculation of a solid density, the principle of Archimedes, and ocean currents. The use of homemade materials and easy-to-use methodologies was contemplated to respond to environmental problems such as contamination of water bodies by plastics. This proposal was implemented in students in the 6th semester during the first half of 2021. As a result, students needed to be able to build arguments and counter-arguments, hypotheses, or questions. In conclusion, it was noted the improvement of science learning by supporting students with homemade experimental activities.
