  Facts
  • Steel is made from iron.
  • In New Zealand our iron comes from black sand but overseas they usually mine iron ore from the ground.
  • The sand gets washed in water and then huge drum magnets are used to separate the iron from the sand.
  • The iron is mixed with coal and then heat is added.
  • The iron separates even more and the frothy muck, called slag, that forms on the surface gets scrapped off as wastes.
  • The iron is then heated up even more until itís like liquid fire or lava from a volcano.
  • Oxygen is blasted into the iron at great force and this turns the iron into steel.
  • The liquid steel is poured into moulds to form huge slabs and sent off to cool.
 
  Did You Know?
  • In New Zealand we get our iron from the black sand along the West Coast between Auckland and Wanganui.
  • Magnets are attracted to steel because it has iron in it.
  • In New Zealand around 1.2 million tonnes of sand is used to make steel.
  • The Glenbrook Steel Mill uses 1200 Gigawatts of power in a year Ė it takes the same amount of electricity to power Wellington City for a year!
 
  Experiments
Use a magnet around your house to find out how many things are made from iron. Try metal door or draw handles, the fridge (be careful not to scratch the paint), pens, safety pins and pegs. Are any of them made of steel or iron?
 
  Investigation
See if you can find out why there is black sand along the coastline between Auckland and Wanganui. (This investigation will be a real blast!!!)
