Improvement in Biological and Geological Sciences LaboratoryInstruction and Student Research Through the Use of a Scanning Electron Microscope

小行星9451844 了解外部和内部微观结构及其化学成分对于了解生物和地质系统的功能和发展至关重要。一个高分辨率，计算机驱动的扫描电子显微镜与冷冻系统和X射线能量色散探测器为本科生提供了一个多功能的教学和研究工具。 冷冻修复消除了数小时的准备时间，这使得SEM可用于许多学生作为与课程相关的实验室练习的一部分。能量色散检测器对于化学成分分析至关重要，这对于必须确定样品的矿物成分的地质学学生和可能查看沉积在叶子上的农药的化学成分的生物学学生来说非常重要。学生将在许多课程的实验室部分使用SEM，但它也将是学生研究的重要工具，这是强烈鼓励的。 通过讲座/演示，实验室练习和学生研究，该项目将影响917名学生/年。

9451844 Burtt Understanding external and internal microstructure and its chemical composition is essential to understanding the function and development of biological and geological systems. A high resolution, computer-driven scanning electron microscope with a cryopreparation system and an X-ray Energy Dispersive Detector provides a versatile teaching and research tool for undergraduates. Cryopreparation eliminates hours of preparation time, which makes the SEM usable by many students as part of laboratory exercises associated with courses. The energy dispersive detector is vital to analysis of chemical composition, which is important for geology students who must determine mineral composition of samples and biology students who may look at the chemical composition of pesticides deposited on leaves. Students will use the SEM in the laboratory portion of many courses, but it will also be an important tool for student research, which is strongly encouraged. Through lecture/demonstration, laboratory exercises, and student research the project will impact 917 students/year.
