1. Mining for Metals

2. Background Information Mining for minerals has been taking place for hundreds of years. Mining for minerals has been taking place for hundreds of years. These minerals are mined to obtain pure metal samples. These minerals are mined to obtain pure metal samples. Some metals are easier to extract than others due to their reactivity. Some metals are easier to extract than others due to their reactivity.

3. The Situation You have been recruited with your lab partner to determine the ease in which several metals will be extracted from an ore. You have been recruited with your lab partner to determine the ease in which several metals will be extracted from an ore. The following metals are to be tested: Al, Cu, Mg, Na, Li, and Pb. The following metals are to be tested: Al, Cu, Mg, Na, Li, and Pb. You have the following chemicals available for testing: distilled H 2 O, 0.1 M HCl, 1.0 M HCl, 3.0 M HCl. You have the following chemicals available for testing: distilled H 2 O, 0.1 M HCl, 1.0 M HCl, 3.0 M HCl.

4. The Assignment – Part 1 You are to create and perform an experiment to test the reactivity of these metals. You are to create and perform an experiment to test the reactivity of these metals. Your experiment needs to be designed such that your results can be reproduced by any pair of lab partners in your class. Your experiment needs to be designed such that your results can be reproduced by any pair of lab partners in your class. Your experimental design must be approved by your teacher before you can conduct the experiment. Your experimental design must be approved by your teacher before you can conduct the experiment.

5. The Assignment – Part 2 After completing your experiment, you need to work with your lab partner to analyze your data. After completing your experiment, you need to work with your lab partner to analyze your data. If necessary, repeat any part of your experiment to verify results. If necessary, repeat any part of your experiment to verify results. Form your conclusions. Form your conclusions.

6. The Report What should be reported? What should be reported? - You and your lab partners name - Your experimental design - Your data - Your analysis of the data - Your conclusions (i.e. which metal is the easiest to extract which metal is the hardest to extract)
