12-Piece Brass Density Cylindrical Bars Set with Wooden Storage

This set of 12 brass cylindrical density bars each have the same 0.5-inch (12.5mm) diameter but different lengths. Includes a wooden storage block. Tolerances are within ±5% of stated dimensions. Some surface oxidation may occur due to humidity and storage; simply scuff off to restore appearance. Suitable for physics classroom experiments exploring the relationship between density, mass, and volume, as well as specific gravity and specific heat. Includes a complete manual with background information and calculation instructions. Required additional materials (not included): a weight device capable of tenths of grams and a metric ruler or caliper.
