Science

On Monday in science we learnt all about Alloys.An Alloy is 2 metals mixed together to form a new metal.For an experiment we turned a two cent coin gold!We put the two cent coin into an evaporating dish of zinc an NaOH on a hot plate.When we took the coin out it was silver and I really wanted to keep mine but then when it cooled down we had to put it back on the hot plate and it turned gold;it was a really fun experiment but our teacher said that the coin will eventually go back to its original colour.
