An introductory general chemistry laboratory course was developed to provide an authentic research experience in environmental chemistry. First- and second-year students learned general chemistry concepts and laboratory skills in the context of snow chemistry while participating in the course-based undergraduate research experience. Students were guided through all steps of the research process, including research question development, data collection and processing, interpretation of results in the context of scientific literature, and both written and oral presentations. A key component of the course was an individual laboratory experiment in which snow samples from the Arctic were analyzed for pH and ion content. Assessment of the course via pre- and postcourse surveys indicated that students, the majority of whom were women, experienced greater gains in confidence of research skills and general attitudes toward chemistry as compared to the traditional general chemistry laboratory course. This course represents a novel integration of environmental chemistry research into an introductory level chemistry laboratory course, and this approach has significant potential to increase student engagement in the sciences.

极地暴跌：普通化学实验室的学期-长雪化学研究

开发了基础化学入门实验室课程，以提供有关环境化学的真实研究经验。一年级和二年级学生在参加基于课程的本科研究经验的同时，还学习了雪化学方面的一般化学概念和实验室技能。在研究过程的所有步骤中都对学生进行了指导，包括研究问题的开发，数据收集和处理，科学文献中的结果解释以及书面和口头报告。该课程的关键部分是一项单独的实验室实验，其中分析了来自北极的雪样的pH值和离子含量。通过课前和课后调查对课程进行的评估表明，学生中大多数是女性，与传统的普通化学实验室课程相比，在研究技能的信心和对化学的一般态度上获得了更大的收获。这门课程代表了环境化学研究与入门级化学实验室课程之间的新型融合，并且这种方法具有极大的潜力，可以提高学生对科学的投入。
