This leads to other question. You have observed that older pennies
before 1982) seem to be a different resght from more recent permes after
1982. You wonder why. Is the difference in weight of the pecunies because
they are not the same size, or because they are not made of the same
metals? Now, it's your job to test the next hypothesis.
e
1 Determine how you would estimate the size of the coins by measuring
the volume of water displaced by the coins.
2 Use the graduated cylinder on the lab table and 10 coins together to
get a better estimate of water displacement and the individual con
size. Do this for both pre- and post-1982 pennies.
3 A simple answer to the question of differences in metal is revealed
when peanies are cat in half. Ask your instructor to show you those
pennes
