Modern biology is increasingly dependent on sophisticated instrumentation and on the interface of this equipment with computers. Due to the expense of this equipment and the sophisticated training required to operate it, undergraduate students receive limited exposure to it. The Reed College Biology Department proposes to add new instrumentation for measurement of photosynthesis in undergraduate teaching laboratories. The equipment has been designed specifically as a teaching aid for undergraduates. It will be used by students in both lower and upper level courses that include Introductory Biology, Plant Physiology, Independent Study, and Senior Thesis. The equipment utilizes an infra red gas analyzer to measures CO2 content of a gas stream passing through a leaf cuvette. Humidity and light are also measured and all data is fed into an attached computer and displayed on a monitor. The computing equipment is already available. Exercises will be designed to demonstrate the fundamental properties of photosynthesis particularly with regards to the effects of environmental variables such as light and temperature. Students, many of whom will be majors from outside of the sciences, will gain familiarity with technology in which computers are used to gather and process data in scientific studies. Upper-level students will make extensive use of the equipment in independent research activities (especially senior thesis projects) that are the hallmark of Reed. Thus the equipment will enhance the ability of Reed to continue to produce students that are eager and competent to advance into graduate school and ultimately careers as professional biologists.

现代生物学越来越依赖于复杂的仪器以及该设备与计算机的接口。由于该设备的昂贵费用以及操作该设备所需的复杂培训，本科生对其的接触有限。里德学院生物系提议在本科生教学实验室中添加用于测量光合作用的新仪器。该设备是专门为本科生设计的教学辅助工具。学生将在低年级和高年级课程中使用它，包括生物学入门、植物生理学、独立学习和高级论文。该设备利用红外气体分析仪来测量通过叶片比色皿的气流中的二氧化碳含量。湿度和光线也会被测量，所有数据都会输入连接的计算机并显示在监视器上。计算设备已经可用。练习的目的是展示光合作用的基本特性，特别是光和温度等环境变量的影响。学生（其中许多是非科学专业的学生）将熟悉使用计算机收集和处理科学研究数据的技术。高年级学生将在独立研究活动（特别是高级论文项目）中广泛使用这些设备，这是里德学院的标志。因此，这些设备将增强里德学院继续培养渴望并有能力进入研究生院并最终成为专业生物学家的学生的能力。
