Density Cube Set

This Density Cube Set is popular because it meets curriculum standards. At a teacher's suggestion, we've just improved upon our largest set of common materials. Each cube is 1 x 1 x 1", large enough to manipulate easily. We've added two new cubes (for a total of twelve): polypropylene and lignum vitae (ironwood).
Polypropylene floats in water, although because it is dense plastic, your students would expect it to sink. Lignum Vitae sinks in water, but because it is wood, your students would expect it to float. Lignum Vitae is three times harder than oak. One of the hardest and heaviest woods in the world, it has a specific gravity of 1.05 and a density of 77-82 lbs/ft3.

Density Cubes, Set of 12 includes: Lignum Vitae, Polypropylene, Aluminum, Oak, Steel, Nylon, Brass, Pine, Copper, Poplar, Acrylic, PVC, Instructions.
