  • Density Samples-All 4 Sets.

    When is one lab four? When it contains samples in 4 different materials. Each set contains 12 specimens of the same material, machined to different lengths. Determine the mass and volume of each sample and graph mass versus volume. The slope of the straight line that results is the density of the material. Includes 12 samples in your choice of 4 materials, wood holder coated in linseed oil for protection from water and instructions.

  • Density Blocks Set of 12.

    We've improved the density experiment in a dozen ways: We've added two cubes to our 10-cube set. Lignum Vitae (ironwood), one of the heaviest and hardest woods in the world, sinks in water, but because it is wood, your students may expect it to float. Polyproylene floats in water, but because it is dense plastic, your students may expect it to sink. 12 one-inch cubes, with instructions and handy storage case.
