Use these precision cylinders in experiments illustrating reciprocal density. The five cylinders are of different materials (aluminum, copper, lead, tin and zinc) and have varying lengths, but exactly the same mass. Students learn that since each cylinderÕs cross-section is the same, their lengths are inversely proportional to their densities. Set of five.
WARNING: CHOKING HAZARD - Small parts. Not for children under 3 yrs.
