Description
Summary:The introduction of recent science discourses around real-world issues into the classroom is challenging for chemistry educators. Carbon sequestration is one potential topic in this respect. On the basis of a demonstration experiment, it is suggested here to use the silicate mineral olivine as a way to introduce the concept of CO2 sequestration. This real-world topic can be used to introduce standard chemistry topics taught in secondary school, such as pH and electrical conductivity. Moreover, students are challenged to employ these concepts and reaction schemes in analyzing the removal of CO2 by olivine.
