Geology (42) The Department of Geosciences at Fort Lewis College has one of the best natural laboratories in the world, but the program lacks an analytical instrument for chemical analyses of rock, soil, or water samples. The capability of the ICP-OES to routinely measure a spectrum of elements in various media makes it the ideal instrument for use in geochemical and environmental curriculum and research. We are adapting exercises developed by Professor Kurt Hollocher at Union College (http://www.union.edu/PUBLIC/GEODEPT/hollocher/pedagogy/mineral_dissolution.htm and http://www.union.edu/PUBLIC/GEODEPT/hollocher/pedagogy/partition_coefficients.htm). Acquisition of an ICP-OES is enriching our program by: 1) allowing the development of field- and laboratory-based analytical projects in introductory and advanced-level undergraduate courses in geology and environmental studies; 2) expanding the opportunities for independent undergraduate-student research in these fields; 3) allowing future K-12 educators to collect and analyze geochemical data in courses required for Education majors and use this information to develop science curriculum; 4) giving students opportunities to incorporate geochemical data into local research projects, both in classes and senior thesis research; and 5) providing increased opportunity for faculty development at a small public baccalaureate-granting institution. The broader impacts of this study include the: 1) increased opportunities for a significant Native American and Hispanic population to participate in undergraduate research throughout the curriculum, from class projects to independent research; 2) use of the instrument by future K- 12 educators in required courses for secondary education degrees, and 3) involvement of undergraduate students in a greater variety of scientific studies to further develop the philosophy and process of scientific discovery. Finally, because this is the only analytical instrument of this type in the Four Corners region, it is serving the larger community, including community colleges such as Dine College and San Juan Community College, local K-12 educators, environmental consulting firms, and the oil and gas industry.

地质学（42）刘易斯堡学院的地球科学系拥有世界上最好的自然实验室之一，但该计划缺乏对岩石，土壤或水样进行化学分析的分析仪器。ICP-OES常规测量各种介质中元素光谱的能力使其成为用于地球化学和环境课程和研究的理想仪器。我们正在改编联合学院Kurt Hollocher教授开发的练习（http：www.union.edu/PUBLIC/GEODEPT/hollocher/pedagogy/mineral_dissolution.htm和http：//www.union.edu/PUBLIC/GEODEPT/hollocher/pedagogy/partition_coefficients.htm）。 ICP-OES的收购丰富了我们的计划：1）允许在地质学和环境研究的入门和高级本科课程中开发基于现场和实验室的分析项目; 2）扩大这些领域的独立本科生研究的机会; 3）允许未来的K-12教育工作者收集和分析教育专业课程所需的地球化学数据，并使用这些信息来开发科学课程; 4）让学生有机会将地球化学数据纳入当地的研究项目，无论是在课堂上和高级论文研究;和5）在一个小的公共学士学位授予机构提供教师发展的机会增加。这项研究的更广泛的影响包括：1）增加了机会，一个显着的美洲原住民和西班牙裔人口参与本科研究整个课程，从类项目，以独立的研究; 2）未来K- 12教育工作者在中学教育学位必修课程中使用该工具，以及3）让本科生参与更多种类的科学研究，以进一步发展科学发现的哲学和过程。最后，由于这是Four Corners地区唯一的这种类型的分析仪器，因此它服务于更大的社区，包括Dine College和圣胡安社区学院等社区学院，当地K-12教育工作者，环境咨询公司以及石油和天然气行业。
