Description

This learning scenario addresses the theme of “ocean acidification”, focusing on the specific problem and its influence on the dissolution of calcium carbonate (impact on limestone and shellfish / clam formations). Starting from real-life questions and through an experimental simulation (the limitations of which students must understand) it is intended that they become aware that human activities can cause a chain of events that sometimes have negative effects on the balance of the ecosystem. Students will use the knowledge acquired in three subjects they studied in secondary school, that have been chosen in order to design the activity and interpret its results, namely results that may not be in line with expectations. One of the objectives is that new questions may arise implying new experimental activities from the point of view of the evolution of scientific knowledge. This STEAM approach is used from an interdisciplinary perspective promoting essential transversal learning according to the new profile of students leaving mandatory education, working on the essential learning of the disciplines involved - Biology and Geology (BG), Physics and Chemistry A (PC) and Philosophy (P), in order to achieve the 21st century skills. This STEAM approach is based on the following pedagogical approach: Inquiry-based science education.
