4 Holders, 12 Al Rods, 12 Brass Rods, 12 PVC Rods, 12 Polypropylene Rods

• (12) Aluminum Rods, (12) Brass Rods, (12) Polypropylene Rods, (12) PVC Rods, 4 Bases to hold all rods
• Rods vary in length from 1.5" to 2.625" per material set
• To determine the density of the material the student plots mass versus volume and the slope therefore is the density (mass per unit volume). Students will need to do all measurements themselves so a balance and ruler are required
• Bases are made from a durable wood coated for years of use
• Machined from top quality raw materials to produce accurate results and durability of decades of use

The perfect demonstrational tool to show that the density of a substance is constant regardless of mass and volume. Using this kit and entire classroom of students can working measuring and calculating densities of the different materials and volumes.
