In this field activity, students conduct a visual survey of a hydrology study site, and collect information about land cover and water quality. These observations are used to stimulate research-able questions about land cover and water chemistry... (View More)

In this activity, students produce a land cover map of a 15 km x 15 km GLOBE study site from hard copies of Landsat satellite images. Students place clear transparencies over the Landsat TM images and use markers to outline and classify areas of... (View More)

In this fieldwork activity, students learn that when setting up a research design a system's boundaries are based on the question(s) a scientist wants to answer. Students ground truth, or validate, a pixel within a homogeneous area of a satellite... (View More)

Students compare soils sampled from different environments and describe their color, texture, and composition. Samples of different soils are mixed with water in small vials, and water soil profiles are compared for difference in particle size and... (View More)

Highly productive commercial agriculture, known as industrial agriculture, is the focus of this investigation. Students will analyze and compare the inputs and outputs of industrial agriculture after reading background information, examining photos... (View More)

Deforestation in Brazil is presented as an example of major environmental changes occurring worldwide. By comparing Landsat images of Rondônia, Brazil from 1975 and 1992, students will analyze the environmental impacts as well as the intended and... (View More)

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)

Thermal images of Earth allow for the visualization and analysis of temperature differences. With the aid of ATLAS thermal images of a shopping mall in Huntsville, Alabama, students examine the impact of the addition of buildings and the loss of... (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)
