A group of high school students and chaperones boarded a bus for historic Oakland Cemetery located in downtown Atlanta. Students explored the site and made observations of the gravestones, many of which were old and run-down. Upon leaving the cemetery, students—based on their interests—developed various chemistry investigations aimed at answering the same driving question: “What is causing the deterioration of Oakland Cemetery headstones?” To engage students in the concept of acids and bases, the project-based chemistry lesson described in this article incorporates the 5E learning cycle and “funds of knowledge.”
