Mesa Community College is developing an organic chemistry laboratory curriculum that uses the natural products found in local native plants as a starting point for guided student inquiry. Objectives of the project include: to identify and isolate materials from native plants; provide training for students on NMR, HPLC, and other key organic laboratory instrumentation; introduce students to a variety of applications of the compounds found in plants, e.g., medicinal, agricultural and other contexts; and encourage student participation in independent study outside the laboratory classes. Students are designing and implementing laboratory activities to extract, purify, and derivatize organic molecules from plants, and are using instrumentation to perform analytical procedures on these compounds. The students are benefiting from hands-on experience with applying actual research methods to contemporary and relevant scientific topics. The project is being evaluated by using formative and summative assessments.Intellectual Merit. This project is advancing both STEM education, by the development of new activities and the pedagogical theme that incorporates local, usable native plants, and chemical knowledge, obtained from the research as students or faculty produce publishable data in the course of the new activities. This project is transforming a laboratory curriculum into guided inquiry exercises by using a broad thematic premise that intrigues and engages students. The focus on local plants provides an interdisciplinary experience, and the possible activities and extensions are numerous. It offers an accessible theme and a simple, flexible approach that is easily modified based on local conditions or student and instructor interests. Local plant materials are readily available: they can be collected by students, if not endangered or protected species; they can be cultivated in campus greenhouses, if necessary; or they can be purchased, often at very low cost. Broader Impacts. In the later stages of the project and beyond, the results of the project will be shared with other institutions through publications, presentations, and web-based dissemination techniques. The project is encouraging a shift in the undergraduate chemistry laboratory experience. The content and pedagogy of organic chemistry laboratories have remained relatively static for years, with increasing recent interest in an inquiry-based approach. The project is adding momentum to that recognized trend based on its scope and distinctive premise. The project also is contributing to the engagement of Hispanic and Native American students in the chemistry curriculum because of its use of native plants that are historically and culturally important to these populations.

梅萨社区学院（Mesa Community College）正在开发一种有机化学实验室课程，该课程使用当地本地植物中发现的天然产品作为指导学生查询的起点。该项目的目标包括：识别和隔离本地植物的材料；为NMR，HPLC和其他主要有机实验室仪器提供培训；向学生介绍在植物中发现的化合物的各种应用，例如药用，农业和其他环境；并鼓励学生参加实验室课程之外的独立研究。 学生正在设计和实施实验室活动，以从植物中提取，净化和衍生有机分子，并使用仪器对这些化合物进行分析程序。学生从实践经验中受益于将实际的研究方法应用于当代和相关科学主题。该项目正在通过使用形成性和总结性评估来评估。 该项目通过开发新活动和教学主题来推进STEM教育，该项目纳入了当地，可用的本地植物和化学知识，从研究中获得的，随着学生或教职员工在新活动过程中产生可发布的数据。该项目正在通过使用吸引学生和吸引学生的广泛主题前提来将实验室课程转变为指导的探究练习。对当地植物的关注提供了跨学科的经验，并且可能的活动和扩展是很多。它提供了一个可访问的主题和一种简单，灵活的方法，该方法可以根据当地条件或学生和讲师的兴趣轻松修改。当地的植物材料很容易获得：如果不濒危或受保护的物种，它们可以由学生收集；如有必要，可以在校园温室中种植。否则可以以非常低的成本购买它们。更广泛的影响。 在项目的后期及其他阶段，该项目的结果将通过出版物，演示和基于Web的传播技术与其他机构共享。该项目鼓励本科化学实验室经验的转变。有机化学实验室的内容和教学法已经相对静止多年，最近对基于询问的方法的兴趣越来越多。该项目根据其范围和独特的前提增加了公认趋势的动力。该项目还为西班牙裔和美洲原住民学生参与化学课程而做出贡献，因为它使用了历史上对这些人群至关重要的本地植物。
