The addition of two environmental chambers to the Biology Department facilities is enhancing laboratory courses (Botany, Ecology, Physiology, Developmental Biology) and student research (required of all seniors for graduation). The two chambers, in conjunction with a biological incubator already available, allow the faculty to establish controlled environments in which experiments with plants and animals can be performed. The chambers are being used in three ways: to compare responses of plants and animals to different environments; to physiologically prepare organisms for experimental treatments; and to maintain organisms in controlled conditions to reduce extraneous environmental variation in experiments in which environmental factors are not designed to be experimental variables. By expanding the types of experiments available to this department and especially by allowing comparative studies of environmental effects on organisms, these chambers greatly enhance undergraduate biology laboratories. Good, clear results from lab exercises with living plants and animals allow students to gain better perceptions of the concepts they read about or hear about in lectures. For student research, the chambers increase precision and accuracy and significantly expand the range of possible studies.

在生物系设施中增加了两个环境室，加强了实验室课程(植物学、生态学、生理学、发育生物学)和学生研究(所有大四学生都必须毕业)。这两个实验室与已经可用的生物孵化器结合在一起，允许教员建立受控环境，在其中可以进行动植物实验。这些小室有三种用途：比较植物和动物对不同环境的反应；为实验治疗做好生物生理准备；在环境因素不是作为实验变量的实验中，将生物保持在受控条件下，以减少无关的环境变化。通过扩大本系可利用的实验类型，特别是允许对生物的环境影响进行比较研究，这些实验室极大地加强了本科生生物实验室。用活的植物和动物进行实验室练习的良好、明确的结果使学生能够更好地理解他们在课堂上读到或听到的概念。对于学生研究，这些实验室提高了精密度和准确度，并显著扩大了可能的研究范围。
