1.
| Prepare a table to summarize the density data you collected.
|
2.
| The accepted values for the densities of aluminum, lead and copper are 2.70, 11.34 and 8.94 g/ml, respectively. You determined the density of a cylinder composed of one of these metals. Calculate the percent error in your determination.

3.
| In the experiment you determined the mass of a stack of ten pennies, the volume of a stack of ten pennies and the density of a stack of ten pennies. What is the average mass, average volume and average density of a single penny?
|
4.
| Legend has it that Archimedes, a Greek Mathematician, determined that a jeweler had cheated King Hieron the 2nd by creating a crown not made from pure gold as he had claimed. If given a piece of "pure gold" jewelry, explain how you might determine if this is really the case.

5.
| You have the penny density values for each of years between 1980 and 1989. Prepare a graph of density versus year. You should observe a discontinuity in the data. Identify between what two years the discontinuity occurs and propose an explanation for it.
