| Summary |
This week's episode of SCOPE stars the very shiny, they very durable - aluminium! From smelting and recycling, to boat building and even a DIY electroscope - we have packed the episode with everything you need to know about this widely used element! ALUMINIUM 101Dr Rob takes us through all the basics of aluminium. This very useful element is found in buildings, aircraft, boats, paint and drink cans and is in fact the second most used metal but where does it come from?ALUMINIUM SMELTINGTo turn alumina into aluminium it needs to go through the process of smelting. Kate Mein the technical manager at Alcoa takes us through the steps of this hot and electrifying process.ELECTROSCOPE EXPERIMENTTo test aluminium's electrical conductivity Junior Scientist, Phoebe, builds an electroscope. Using al-foil and creating some static electricity Phoebe has some very interesting results.BOAT BUILDINGTo turn sheets of aluminium into a boat you need some pretty amazing machines. Jacqui White from Telwater shows us some of the steps in the creation of these boats from the very cool plasma cutter to shaping and welding. FLOCCULATIONFlocculation is a funny sounding word but it is also the process of using aluminium sulphate to make water clean. David Cook from SA Water explains how aluminium is used to remove impurities from water to make it clean enough to drink.ALUMINIUM RECYCLINGHugh Cotton from Sims Metal Management shows us how he melts down scrap aluminium like drink cans, car wheels and lawnmowers in molten furnaces down to ingots that contain at least 80% aluminium. These ingots will be used again to make new aluminium objects |
