Students will compare aerial photos of their area from the past with current photos, noting differences and then conducting ground truth investigations to determine what happened. Finally, students will use the information they gather about past... (View More)

Students will examine two satellite images of their local watershed taken at different points in time and use this data to learn about changes in the watershed, particularly in land cover. Next, they describe how these changes have had positive or... (View More)

Students describe the interaction between the river, its quality and the lives of people in the watershed where they live. Students will design a questionnaire, interview local people, and compile the oral histories collected to establish the recent... (View More)

In this investigation students explore how resolution affects information content on remotely sensed images, relate remote sensor resolution (pixel size) to information content, and gain an understanding of the information content of different kinds... (View More)

Through a field trip along a local water course students will conduct a visual survey to discover information about local land use and water quality. They will document their findings with mapping and compilation of a river profile and use this... (View More)

In this activity, students explore how maps and models are used to represent the landscape. Students will recreate their school grounds in a sandbox, clay, or a cardboard model. They will then photograph or videotape their model from above and from... (View More)

Students will use remotely sensed images and topographic maps to classify land cover types in their watershed. A field trip to specific sites will allow the students to ground truth cover types found on the remotely sensed images and extrapolate... (View More)
