  • Demo is to place a piece of copper in magnesium sulphate, then a piece of magnesium in copper sulphateUse huge beakers and pieces of metal to aid visibilityExplain how a reaction shows that Mg has displaced the Cu from the sulphateTalk about why the Mg displaces the Cu, but not the other way roundBe quick – the practical takes most of the lesson!
  • Remind several times how to spot a reaction – it’s the colour difference (versus the water drop)
  • An alternative to 4.14 could be to set light toballoons of H and He. The He will still burst (because of the pressure) but not as loudly as H!
