DNRDST-05 Density Rod Set – Five Equal Mass Rods of Different Materials – PVC Brass Polyethylene Aluminum and Nylon – Physics Density and Mass Experiment Kit for Classroom or Lab

This Density Rod Set helps students explore the fundamental relationship between mass, volume, and density. The set includes five rods—each of equal mass but made from different materials: PVC, brass, polyethylene, aluminum, and nylon. With a consistent 12mm diameter and varying lengths, the rods clearly illustrate how density affects material properties. Perfect for physical science and physics education, this set provides a hands-on way to reinforce theoretical lessons and engage students in STEM experiments. Instructions are included for classroom demonstrations.
