• Part of the Understanding Our Environment project that is designed to engage students in investigating specific environmental problems through concrete activities and direct experience, this unit introduces students to the idea of natural resources and focuses on resources found on land: minerals such as hematite and gypsum; rocks such as granite and limestone; fossil fuels such as natural gas, coal and oil; and surface deposits such as soil, sand, and gravel. Students study characteristics of natural resources and sources of human-made materials, and learn how use of natural resources affects the environment. Objectives include: learning what types of materials, both natural and made by humans, are in the local environment; understanding how the land's natural mineral resources are identified, obtained, and used by humans; finding out the origin, composition, and sources of the materials in our environment; studying the development of landscape and special properties of soil; and considering what people can do about environmental damage caused when humans obtain natural resources from the land.
