What is Density Analysis of Pre-1982 Pennies about?

The document describes an experiment to determine if a penny with its date scratched off was minted before or after 1982 using density measurements. A forensics technician will measure the density of the penny by determining its mass and volume in water. Pennies made before 1982 contain more copper and will have a higher density than those made after 1982, which contain more zinc. The experiment involves measuring the mass and displaced water volume of samples of pre-1982 and post-1982 pennies to calculate
