The acquisition of a steady state porometer, portable leaf area meter, portable photosynthesis system, and accessories for these instruments plus a portable computer will provide the students with an opportunity to utilize state-of-the-art instrumentation to measure and analyze growth, productivity, and photosynthesis data in freshman, junior, and senior laboratory courses designed to teach plant physiological and ecological principles as well as enhance undergraduate research projects in the plant sciences. Experiments are designed so that students use the new instrumentation to make transpiration, leaf area, and photosynthetic measurements on a number of different plants grown under a variety of different environmental conditions in both the laboratory and field. In each experiment the instrumentation will provide a means by which students can: (1) formulate and test hypotheses related to important physiological and ecological concepts; (2) gain hands-on experience with state-of-the-art equipment; (3) conduct experimentation which reinforces important physiological and ecological principles; (4) examine the proper methods of experimental design; (5) gain first-hand experience in the collection, analysis, and interpretation of scientific data; and (6) report on the experimentation in a scientific journal format.

获得稳态孔隙计、便携式叶面积计、便携式光合作用系统以及这些仪器的附件，再加上一台便携式计算机，将使学生有机会利用最先进的仪器来测量和分析一年级、三年级、三年级的生长、生产力和光合作用数据。高级实验课程旨在教授植物生理学和生态学原理，并加强植物科学本科生的研究项目。实验设计的目的是让学生使用新的仪器在实验室和野外的各种不同环境条件下对许多不同的植物进行蒸腾、叶面积和光合作用的测量。在每个实验中，仪器将提供一种方法，学生可以：(1)制定和测试与重要生理和生态概念相关的假设；(2)获得最先进设备的实践经验；(3)进行强化重要生理学和生态学原理的实验；(4)审查适当的实验设计方法；(5)获得收集、分析和解释科学数据的第一手经验；(6)以科学期刊的形式报道实验结果。
