Copper is a metal that has grown in value. Some people are even hoarding old pennies made in Canada in order to cash in on the copper!!! The question is... how much of a penny is made of copper?? If each penny is actually made of pure copper, then one penny (that no longer has value in Canada) actually is still worth 1 penny's worth as a metal!! In the future, it could even be worth more!!!
In today's experiment, we are going to compare the penny with some pure copper mesh to find out if pennies are really made out of pure copper.

BIG IDEA: What would you have to do before you determine that a substance is a pure substance and not a mixture????
