Students confront the challenge of improving global agricultural production in order to feed increasingly larger populations. Students evaluate tables, maps, graphs, photos and satellite images detailing global population growth patterns and... (View More)

Subsistence agriculture is introduced and described through text, satellite images, space shuttle photos, ground photos and maps. After reviewing all resources, student teams debate whether intensive subsistence agriculture (e.g., rice production)... (View More)

The use or abuse of the Chesapeake Bay is examined and discussed in the form of a student role-playing activity. Each student gathers relevant background information and formulates questions from briefing cards included in the investigation. Ten... (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)

Students examine a series of remotely-sensed images of the US, scaling from the continent to San Francisco, and distinguish the concepts of scale and resolution. At greater resolution, students are able to identify different land classes on the map,... (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 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 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)
