Extended four week research task – final piece due: Wk beginning 12 th Oct (your first lesson that week!) Self and peer reviews will be done in week 3, so you must complete each section on time (see moodle) Using information not yet covered – you will need to use your textbook and other resources Diagrams ONLY can be copied, cut and paste will not be adequate and will result in you repeating the work Source material AND copied diagrams must be referenced correctly. Homework

You will be expected to be able to explain that most metals have to be extracted from their ores, which are found in the Earth’s crust. You will need to explain how to extract a metal using carbon and relate the reactivity series to the extraction method. You will need to be able to explain the electrolysis of aluminium. You will need to discuss the abundance of these metals and the relative costs of each type of extraction. How do you get the metals that I use every day?

You decide to seek your fortune as a metal supplier. The problem is, you can’t decide which metal to specialise in. You know that you will have to extract the metal from the Earth’s crust. 1. Put together information about the extraction of gold, iron and aluminium. 2. Use as much science as you can, including equations, as well as process details. 3. Compare how easy the extraction will be and how this is likely to affect your metal choice. More detail……… Moodle for timetable
