So exactly what was in that gold medal that Usain Bolt
won?
Duh! Gold, silver and bronze, right?
Wrong!
The last Olympic gold medal that was made from gold was awarded
in 1912.
So what are Olympic medals made of?
It is very expensive to make the medals out of gold, silver and
bronze. Those metals are quite rare.
Instead, cheaper metals are used. Every athlete still wants to
win a medal, no matter what the medal is made of!
The London 2012 Olympic medals are lighter that the Vancouver
Olympic medals, because 5,000 more medals will be awarded.
If the Summer Olympic medals were the same weight as the Winter
Olympic medals, it would be very expensive to make them all!
