Buoyancy and Density


F.4(1) - Buoyance/Density of Soda Cans


With a transparent tank filled with water, it can be shown that the overall density of a can of Diet Coke/Pepsi is less than that of water, while the density of a Classic Coke/Pepsi is greater. The Diet Coke/Pepsi can float in the tank while the Classic Coke/Pepsi can hits the bottom.

F.4(2) - Density Cubes - Six Metals

In this demo students identify each metal cube by determining its density. Each set includes one cube each: aluminum, brass, copper, steel, iron, and zinc.

F.4(3) - Steel Sphere Density Kit

These two metal spheres have about the same mass, one has a diameter of 2.86 cm and the other a diameter of 12.7 cm, making there densities vastly different.

F.4(4) - Viscosity Tubes

Viscosity Tube set consists of five transparent plastic tubes containing oils of five different viscosities. A faster traveling chrome steel ball and a slower Teflon ball in each tube travel at constant speeds, which depend on the viscosity of the oil, the angle at which the tube is inclined and to some extent on the temperature.
