- Uranium: Teacher Background Information
- Vocabulary Materials
- Uranium Mining Methods Worksheet (one per student, pair or group) and Uranium Mining Methods: Teacher Answer Key
You may choose to have students complete the entire activity within one or two class periods. If time or computer access is limited, the activity can be introduced, completed outside of the class and concluded in another class period.
- Ionizing radiation
- Radioactive atom
- Uranium milling
- Uranium mining
- Start with a vocabulary activity if students are not familiar with uranium and the vocabulary used in this activity.
- Explain that the U.S. uranium mining boom started in the mid-1940s. Once the U.S. built a stockpile of uranium in the 1970s, the mining industry slowed. Uranium mining is still in operation, but on a much smaller scale. The U.S. mining industry uses two distinct methods to extract uranium ore: physically removing the ore-bearing rock from the soil for processing or chemically dissolving uranium from the ore at the site.
- Provide students with a Uranium Mining Methods Worksheet and review the directions. Students can form hypotheses based on their present knowledge or allow them to access any available resources, such as the Internet, library or school books or individuals who may have insight on mining and environmental issues.
- Conclude by having students share their responses. You can reference the Uranium Mining Methods: Teacher Answer Key. Compile the “for” and “against” votes to see which method the class would be in most favor of, or if they would not want to allow mining in their community.
- Optional activities or extensions: Have students:
- Debate the pros and cons of the different mining methods.
- Develop models or drawings that show the mining process and impacts on the earth, people and our environment.
