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 MYPond project is an investigation of the chemical reactions, biological processes and inflow/outflow balances found within a pond environment. Instrumentation has been established in two ponds near each other so that a variety of chemical and physical properties are measured at various depths at 15-minute time intervals. Data can be viewed either in real-time or accessed from an archive, and ... Full description.

Users can read and view pictures as part of a discussion of the positive and negative impacts of dam building on the streams, rivers, and watersheds in the United States and in Egypt. Conservation measures intended to increase the availability of water for fish and wildlife are outlined, and a link to the Dam and Reservoir Impact and Information Archive is provided. This archive is an extensive collection ... Full description.
