Abstract Under the theme of preparing calcium carbonate from oyster shells,the project incorporates sustainable development principles through three sub-tasks: Techniques for extracting calcium,methods for generating calcium,and approaches for refining calcium. Employing digital experiments to quantitatively investigate reaction conditions,it guides students in using AI-assisted tools to complete the entire process: from identifying waste components and separating substances to producing end products,thereby enhances their ability to solve real-world problems.
