From 1793 – 1837, the penny was pure copper. For the next 20
years, the penny was bronze, which is copper, tin and zinc. From
1857 – 1863 the cent looked whitish because it was made of copper
with 12% nickel. For the next 98 years (1864-1962!) the penny was
again bronze, except for 1943. Because of the need for copper
during WW II, the cent was zinc-coated steel in 1943. In 1962 the
tin was removed from pennies, making them 95% copper and 5%
zinc. In 1982 this was changed to 97.5% zinc and 2.5% copper

Safety
Set-up Sketch:
= How the equipment was used
= be careful about….
-- wear goggles
Operational Definition
= how the dependent/responding variable is
measured
number of drops will be one less than overflow
Clean up = what
needs to be done at the
end of the lab
• Wipe down table
• Return flasks & other
equipment to back
counter

I didn’t think water would pile up
and make such a big mound on a
penny!
The 3 pennies really looked different
from each other

Both graphs show that the 1943 penny held the
most drops, the 1984 held the second highest
number of drops and the 1963 penny held the
least amount of drops.
It can be inferred that the 1943 penny holds
more water than the 1963 or 1984 pennies.
