In Science, Willow Class has been looking at properties of materials. Today they looked at electrical conductors.
The challenge was to find the metal with the least resistance and most conductivity. To test different metals the children wired up a circuit with a bulb and inserted the metals to complete the circuit.
The metals tested were steel, iron, brass, copper, aluminium, gold, silver and platinum (care-of Mrs Burr's engagement ring!!).
There were some surprising results! Each group found that silver had the least resistance. However, when pitching their findings to the football club owners as to which metal to make the circuits within the floodlights, many of the companies decided that aluminium or copper would be better due to cost reasons. Very sensible advice.
A great afternoon's science.
