This textbook chapter introduces the buffalo as a keystone species, and describes the environmental impacts of its near extinction, including today’s predominance of non-native species in the Great Plains. Human activities that contribute to... (View More)

In these activities, students continue to explore the idea of interaction among Earth components as they identify processes in the Earth system and indicate how they illustrate an interaction between two of the Earth system components. Uses commonly... (View More)

In this hands-on activity, students conduct bottle experiments to learn about the conditions that best facilitate the decomposition of organic material in soil. In the lab, they observe changes in the decomposition of vegetable scraps by varying the... (View More)

In this simulation exercise, students determine where to place a hosptial using a classified land cover map to make environmentally sound land use decisions. Results are presented in a mock town hall meeting. A student worksheet is included within... (View More)

In this laboratory activity, students analyze soil samples from their homes to identify soil properties and learn about soil classification. Soils sampled by students from different environments are compared, and students ask questions about the... (View More)

This learning activity familiarizes students with the concept of modeling as it is related to remote sensing and to the process of digitizing images. Students create a digitized image of a map that they have created, and through this activity... (View More)

This activity helps students understand the connections between remote-sensing technology, computer imagery and land cover assessment, and models how a satellite sensor communicates information to a computer. Digital information from a map created... (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)

Remote sensing offers three perspectives on human or physical features: aerial (birds-eye), oblique (angled) and ground-level. Sketching a classroom object from each of the three perspectives provides students with the foundation to then complete... (View More)

In the culminating activity of this investigation, students write an editorial entitled, Are We Warming Earth?, in which they attempt to persuade readers to take global warming seriously. Leading up to that activity, students read background... (View More)
