Metal Density Cubes, 20mm, Set 6

Metal Density and Immersion Cubes Set – 6 Metals/Alloys, Equal Volume (20 mm) for Physics Lessons

The set includes six metal cubes of equal volume (20 mm edge length) made from different metals and metal alloys: copper, brass, lead, zinc, steel (or iron alloy), and aluminium.
Because all cubes have the same volume, differences in mass, density and buoyancy become immediately visible and measurable, making the set ideal for physics lessons on mass (weight), volume, buoyant force and density comparison.

Designed for classroom discussions on the properties of solids (weight, buoyancy, and volume) and for determining and comparing the densities of various materials.

These blocks are suitable for hands-on experiments, allowing students to observe how density influences weight and buoyancy, and to compare the densities of the different materials included.

• Six cubes with identical volume
• Materials: copper, brass, lead, zinc, steel (or iron with alloying elements), aluminum
• Edge length: 20 mm

Suggested experiments (easy to run in class):

• Density calculation (core experiment),  
• Mass vs. volume concept check,  
• Buoyant force / apparent weight in water,  
• Archimedes’ principle (displaced volume),  
• Float/sink comparison across liquids, 
• Material identification challenge.
