This project will improve the laboratories of those undergraduate courses in Northeastern Illinois University' s Earth Science curriculum that address concepts in mineralogy, petrology, and high temperature geochemistry. The primary objective is to revise selected lab exercises and incorporate extended group projects that are constructivist in approach, making maximal use of our existing facilities. The acquisition of the rock-preparation equipment requested here will make it possible to implement exercises that will utilize our X-ray diffractometer, atomic absorption spectrophotometer, high temperature furnaces, and petrographic microscopes in a practical and efficient manner. With the changes outlined in this proposal, students will learn key mineralogic and petrologic concepts as they use a variety of analytical equipment to conduct their own experiments, gather their own data, and examine samples of their choosing.

该项目将改善伊利诺伊大学东北大学的地球科学课程的实验室，该课程涉及矿物学，岩石学和高温地球化学的概念。主要目的是修改选定的实验室练习，并结合构造主义者的扩展小组项目，从而最大程度地使用我们现有的设施。此处要求的岩石制备设备的采集将使实施我们的X射线衍射仪，原子吸收分光光光灯，高温炉和岩石学显微镜以实用和高效的方式实施锻炼。随着该提案中概述的更改，学生将使用各种分析设备来执行自己的实验，收集自己的数据并检查自己选择的样本，从而学习关键的矿物学和岩石学概念。
