Archimedes’ Buoyancy Challenge: Density of a Penny Goal: To use Archimedes’ Principle to find the density of the density of pennies, correct to two significant figures. Theory: Sunken(1) Floating(2) F p,1 F p,2 W 0 W 0 F net = F p,2 - W 0 =0 F p,2 =W 0 P w *g*V w,2 =m 0 *g m 0 =p w *V w,2 density=m 0 /V w,2 Materials: 10 post-1982 pennies 1 Empty plastic film canister 1 film canister lid Overflow cup 500 ml graduated cylinder Centimeter ruler Method: Initially, we filled the 500 ml graduated cylinder up to the 400 ml mark with water. We then placed 19 post-1982 pennies into the graduated cylinder and read the difference in water markings. The difference between the new and original markings was the volume of 19 sunken pennies. We poured out the water and dried the pennies, and the refilled the graduated cylinder to the 400 ml mark. Next, we

placed 10 post-1982 pennies in a film canister and gently placed the canister into the graduated cylinder. The difference in the water mark now and the original was the volume that 10 floating pennies occupied.
