This project will incorporate physiological instruments, data acquisition systems, and simulation modeling software in courses which emphasize whole plant physiology and environmental biology. Analytical capabilities will be enhanced at the advanced levels and in introductory courses. Exercises will emphasize student directed experiments and will focus on complex phenomena where experiments will be guided by simulation models and theory. Students will interface data acquisition systems and Macintosh computers with thermocouples, light sensors, hygrometers, and CO2 analyzers as they explore the mechanistic controls of photosynthesis and obtain calculated results on line. A plant stress meter will assist students to understand the photochemical reactions of photosynthesis and monitor photosynthetic capabilities under a variety of conditions. These complex but realistic exercises will be interpreted and presented by teams of students. Ecological studies will be helped by addition of a plant canopy analyzer, a porometer, a water potential system and a Hydrolab Surveyor 3. Small group interactions will be fostered.

该项目将把生理仪器、数据采集系统和模拟建模软件整合到强调整体植物生理学和环境生物学的课程中。分析能力将在高级课程和入门课程中得到加强。练习将强调学生指导的实验，并将重点放在复杂的现象上，其中实验将由模拟模型和理论指导。学生们将把数据采集系统和Macintosh电脑与热电偶、光传感器、湿度计和二氧化碳分析仪连接起来，探索光合作用的机制控制，并在线获得计算结果。植物压力计将帮助学生了解光合作用的光化学反应，并监测各种条件下的光合作用能力。这些复杂但现实的练习将由学生小组进行解释和展示。将通过增加植物冠层分析仪、气孔计、水势系统和水实验室测量员3来帮助生态学研究。将促进小组互动。
