12-Piece PVC Density Cylindrical Bars Set with Wooden Storage

The Eisco Labs PVC Cylindrical Bars Density Set provides 12 PVC cylinders of identical 0.5" (12.5mm) diameter but varying lengths, allowing students to explore the relationship between mass, volume, and density. As bars of the same material change in size, learners can demonstrate that density remains constant even while mass and volume change. The set ships in a wooden storage block. Part of the Eisco Labs Density Investigation series, the set includes a complete manual covering the basics of density, mass, and volume along with calculation instructions. Designed for educational use; expect tolerances within ±5% of stated dimensions.
