The purpose of this resource is to familiarize students with the importance of perspective and various scales of remotely sensed data. Students create a 3-D model of an area and develop a classification system for the landforms in their model. The maps can then be used to answer certain questions about the environment. Full description.

The purpose of this resource is to familiarize students with modeling as it relates to remote sensing and digitized images. Students will use the symbolic map created in the beginning activity to produce a digitized image and begin to see why ground verification of satellite data is necessary. Full description.

The purpose of this resource is to introduce students to the concept that sometimes there is no one "right" answer to a question or measurement. Students learn to be careful when searching for a right answer to questions such as 'What time is it?' by comparing multiple measurements of the time of day. Students gain an intuitive understanding of the characteristics of imperfect measurements. Using ... Full description.

The purpose of this resource is to develop a classification system for a set of objects and learn about hierarchical classification systems. Any set of objects, such as insects or rocks, may be used as well. Full description.

The purpose of the resource is to introduce students to Landsat images and how to identify the land cover types within those images. Full description.

The classroom activities presented here are designed to make learning and demonstrating non-point source water pollution concepts exciting and fun. The activities may be used alone or as extensions to an existing curriculum. Concepts include the water cycle, drinking water source and treatment, groundwater and aquifers, surface water and watershed protection. A glossary and correlation to the 1994 ... Full description.

In this lesson, students explore how groundwater contamination can spread through aquifers by participating in a groundwater plume simulation. Students will consider where they would look to determine the source of groundwater contamination and where they could turn for assistance; explore the possible contamination of Nevada groundwater by a major nuclear test site by reading and discussing, "Concerns ...

This is an online activity book from the National Weather Service that teaches about hazardous weather. The site also includes links to kids sites for the Federal Emergency Management Agency (FEMA) and the National Oceanic and Atmospheric Agency (NOAA). Full description.

Finding water for growing urban areas and agricultural use is a major problem in most regions. This site provides the user with the opportunity to examine many of the options available to communities to expand their water resources base, as well as the pros and cons of each option. Specifically, the activity focuses on the following options: dam a river and create a reservoir to store water, dig more ... Full description.
