DNRDST-MTL Density Rod or Equal Mass Set – 5 Metal Rods of Equal Mass for Density and Water Displacement Experiments – STEM Physics Classroom Tool

Density Rod or Equal Mass Set provides a clear and engaging way to study density, mass, and volume relationships. Each of the five metal rods—tin, aluminum, steel, zinc, and copper—has an equal mass of 30 grams but different lengths due to their varying densities. Using the water displacement method, students determine each rod’s volume and calculate its density. By comparing their results to known values, they can identify each material and better understand how atomic structure influences mass and size. This hands-on kit reinforces core physical science concepts and is ideal for STEM labs, physics classrooms, and student experiments.

• Includes 5 metal rods each weighing 30 grams: tin, aluminum, steel, zinc, and copper
• Demonstrates how materials with equal mass can have different volumes and densities
• Students calculate density using the water displacement method for hands-on learning
• Encourages exploration of atomic structure, mass, and volume relationships
• Perfect for physics, chemistry, and general science classrooms or STEM programs
