Service-Learning in Chemistry: Lead in Soil from Vehicle Emissions

化学（12）化学系正在将一个基于环境的服务学习实验室整合到第一年的化学课程中，以激励学生学习，加强整个课程的联系，并在当地社区促进科学，数学和工程。一年级化学实验室的学生将获得处理真实世界样本的经验，根据他们收集的数据的统计评估做出和检验假设，生成案例研究数据以供随后的共同核心课程考虑，在团队中有效地工作，探索公共政策与更广泛社区环境化学之间的联系，并通过口头或书面报告将他们的结果传达给技术和非技术受众。我们一年级化学课程的学生计划，取样，并测试整个社区车辆排放的土壤中的铅。在此过程中，他们将与概率和统计课程的学生、当地小学的学生以及加州儿童铅中毒预防计划合作。在这个项目中收集的数据将在一年后的概率和统计数学课程中被学生重新审视，使他们能够进行更复杂的分析。该实验室模仿了芝加哥洛约拉大学、犹他大学和卡拉马祖学院的服务学习一般化学项目，这些项目使用原子吸收光谱来测试当地社区的铅。

Chemistry (12)The Chemistry Department is integrating an environmentally-based service-learning laboratory into the first-year chemistry course in order to motivate student learning, enhance connections throughout the curriculum, and promote science, mathematics, and engineering within the local community. Students in the first-year chemistry laboratory gain experience dealing with real-world samples, make and test hypotheses based upon statistical evaluation of data they have collected, generate case-study data for consideration in subsequent common core classes, work effectively in teams, explore connections between public policy and environmental chemistry in the wider community, and communicate their results to both technical and non-technical audiences through oral or written reports. Students in our first-year chemistry course plan, sample, and test for lead in soils from vehicle emissions throughout the community. In the process they will collaborate with students in a probability and statistics course, students at a local elementary school, and the California Childhood Lead Poisoning Prevention Program. The data collected in this project will be revisited by students a year later in a mathematics course in probability and statistics, allowing them to undertake more sophisticated analyses. The laboratory is modeled after the service-learning general chemistry projects at Loyola University of Chicago, the University of Utah, and Kalamazoo College which employ atomic absorption spectroscopy to test for lead in the local community.
