• Resumen

  • We describe a set of laboratory exercises centered on a theme of copper pollution and phytoremediation for first-year general chemistry. The chemical concepts covered include: equilibrium, thermodynamics (Gibbs free energy, enthalpy, entropy), redox reactions, and chemical kinetics. We report strong conceptual learning and enhanced affective outcomes for students in the course.
