Discipline: Earth System Science (40)This project is developing a project-based laboratory course in Forensic Geology, presented at a level that is accessible to any student, which introduces students to the principles of Earth Science and their application to forensic science, which allows Earth Science and Science Education majors to apply their knowledge in a novel way. The course makes use of a research-grade X-ray diffractometer (XRD) and other analytical instruments, and emphasizes team learning, with the students working in groups where individuals act as "team experts" on some aspect of the course. A research-grade XRD is necessary to this work because it can perform micro-diffraction and thin film analysis, capabilities that the current generation of compact diffractometers lack. Students in the Forensic Geology course use the XRD to analyze soils, coals and/or ores to identify source areas; to identify the minerals in cosmetics and paints; to analyze building materials and safe insulation; and to track the origin of contaminants. The XRD is also being incorporated into existing courses in Mineralogy and Applied Environmental Methods. The intellectual merit of the project includes introducing students to Earth Science via real world examples, and training them in the principles of forensic geology, raising awareness of this discipline. The broader impact of utilizing the inventive combination of forensics and earth science should enhance science education and the uniqueness of this approach is expected to attract more students to an Earth Science course and increase understanding of geology among undergraduates in several disciplines.

专业：地球系统科学（40）该项目正在开发一个基于项目的法医地质学实验室课程，以任何学生都可以进入的水平呈现，向学生介绍地球科学的原理及其在法医学中的应用，这使得地球科学和科学教育专业的学生能够以新颖的方式应用他们的知识。 该课程使用研究级X射线衍射仪（XRD）和其他分析仪器，并强调团队学习，学生在小组中工作，个人在课程的某些方面担任“团队专家”。 研究级XRD对于这项工作是必要的，因为它可以进行微衍射和薄膜分析，这是当前一代紧凑型衍射仪所缺乏的功能。 法医地质学课程的学生使用XRD分析土壤，煤炭和/或矿石，以确定来源区域;识别化妆品和油漆中的矿物质;分析建筑材料和安全绝缘;并跟踪污染物的来源。 XRD也被纳入矿物学和应用环境方法的现有课程。该项目的智力价值包括通过真实的世界例子向学生介绍地球科学，并在法医地质学原理方面对他们进行培训，提高对这一学科的认识。利用法医学和地球科学的创造性组合的更广泛的影响，应加强科学教育和独特的这种方法，预计将吸引更多的学生到地球科学课程，并增加地质学在几个学科的本科生的理解。
