Rocks, Minerals, and Erosion


J ILLUSTRATIVE EXAMPLE J
In addition to exploring the living things around them, students should also become familiar with the earth materials that make up their world. They should be provided with opportunities to learn that rocks are used for many things within a community and that rock characteristics help determine their use. Students can then explore the changing landscape by examining the processes of erosion, transport, and deposit; and determine how wind, water, and ice reshape the landscape. An examination of these processes also leads to discussions of ways that humans prevent landscape from changing or adapt to a changing landscape. This illustrative example emphasizes the relationships between science and technology.

Exploration
Students explore rocks found around them. The above exploration may lead to the following question:

Development
Students investigate the physical properties of rocks.
