1. Earth Science and M.E.A.P The benchmarks and you!

2. EG. Geosphere Benchmark 3 Explain how common objects are made from earth materials and why earth materials are conserved and recycled.

3. Valuable materials: Minerals—diamonds, salt, sulfur, etc. Metallic ores--iron, copper, aluminum, etc. Fuels—coal, natural gas, petroleum Key concepts

4. Types of Resources Renewable Nonrenewable Key Concepts http://www.nrcs.usda.gov/

6. Mining = mineral extraction from rock http://www.fsengineer.com/images/mining.jpg

7. Metallic Ores are minerals such as copper, iron, aluminum, etc., that can be mined at a profit. What is an ore?

13. Mining Key concepts: Refining Manufacturing

14. Conservation Limits Recycling Costs for developing more remote supplies Recycling processes melting, shredding, dissolving Key concepts:

15. Manufacturing processes—steel mills, auto assembly lines, paper making Real-world contexts:

16. Local recycling center for materials, such as glass, plastic, aluminum, steel cans, motor oil

17. Examples of technical and social means for slowing the depletion of earth’s resources, such as developing more fuel efficient cars and mandating their use

18. Disposal in landfills and incinerators.
