My Digital Watershed

my digital watershedAnalyzing Watersheds in Google Earth

by Tim Norris and Will Federman

Students perform a computer lab activity to answer basic geographic questions about the watersheds in which they live. This module is an opportunity for students to: 1. Learn how to read topographic maps, 2. Use computers and GIS to visualize topographic information, 3. Learn how to draw using a computer, 4. Learn how to measure area and distance using a computer, and 5. Learn how to interpret satellite imagery to answer basic questions about land-use.

Remote Sensing and the Electromagnetic Spectrum

by Kristin McCully and Jack Horner

Students learn what remote sensing is, how it works, and how scientists use it, with a focus on Landsat satellite and imagery. They create, and then interpret, a remote sensing image of a planet and remote sensing imagery available on the Internet. Students review the structure of a wave; solve problems using speed, wavelength, and frequency; and discuss the uses of each type of radiation in the electromagnetic spectrum. Finally, students examine and analyze a remote sensing image of a rain forest.
