Exploring the Environment (ETE), a NASA Classroom of the Future hosted by Wheeling Jesuit University, aims to teach high school students collaborative scientific inquiry and analysis through use of remote sensing technology and the Internet. The modules contain introductory activities to familiarize users with remote sensing software and images. Twelve modules are divided into three categories, Basic, Comprehensive, and Advanced. Modules range in topic from weather to water quality to mountain gorillas. Each module contains an in depth lesson with definitions, concepts, activities, and problems to solve. The modules are designed for a group of students to work together to resolve the given situation. The Teachers Pages provide instructors with information about each module, helpful hints for planning, facilitating, and assessing modules, and Teacher-to-Teacher, a section under construction where teachers will be able to share their thoughts and ideas related to the module subjects.
