Fraud detection – testing metals
In this project students use a Eureka can to calculate the density of copper, brass and silver coins to three decimal places to determine whether they are pure metals. They can investigate:
• How to use a Eureka can to prove that a modern 1p or 2p ‘copper’ or ‘bronze’ coin is neither pure copper nor bronze.
• Whether modern 1p and 2p coins made from the same metal?
• Does the density of these modern 1p and 2p coins differ from those minted before 1992?
• Were the original decimal coins (pre-1992) made from the same metal as pre-decimalisation pennies and halfpennies (1d and ½d)?
