The addition of fully automated scanning electron microscopy to the undergraduate biology laboratories at North Hennepin Community College (NHCC) will make possible a level of science instruction at the lower-division that was, before this time, reserved only for upper-division and graduate students. Using an older, manually operated Scanning Electron Microscope(SEM), a pilot project with SEM applications for lower-division college students has demonstrated that SEM lab experiences generate a greater interest in and understanding of science subjects. A fully automated, user friendly SEM will permit the following changes to be made in the Biology Department: (1) A new course focusing on techniques in structual biology that includes a student research componen will be added; (2) students studying cell and molecular biology will have enhanced hands-on lab experience in the examination of cellular and tissue structure; (3) all students in introductory biology will have an opportunity for firsthand operation of a SEM -The experience itself and the micrographs produced will supplement other laboratory and lecture materials used for the study of intricate structures; and (4) laboratory demonstrations for visiting secondary school students and opportunities for research projects by visiting college and secondary school educators will increase.

全自动扫描电子显微镜的加入， 北亨内平大学的本科生生物实验室 社区学院（NHCC）将使科学水平成为可能 在此之前，在较低级别的教学中， 只为高年级学生和研究生保留使用 一台老式的手动扫描电子显微镜（SEM）， 一个试点项目，为较低级别的部门提供SEM应用程序 大学生已经证明，SEM实验室的经验， 激发对科学的兴趣和理解 科目 全自动、用户友好的SEM将允许 生物系将进行以下更改：（1）A 新课程侧重于结构生物学技术， 包括一个学生研究组件将被添加;（2） 学习细胞和分子生物学的学生将提高 在细胞检测和 组织结构;（3）所有生物学入门学生将 有机会亲自操作SEM -The 经验本身和显微照片将补充 用于研究的其他实验室和讲座材料 复杂的结构;（4）实验室演示， 探访中学生及提供机会， 通过访问大学和中学的研究项目 教育工作者将增加。
