Baluue STEM Density Cube Set 4-Pack 20mm Brass, Iron, Aluminum & Wood Blocks for Archimedes Principle & Specific Gravity Labs School & Classroom Science Kit

Features

• 4-IN-1 MATERIAL EXPLORATION: Includes 4 distinct 20mm (0.79 inch) cubes: Solid Brass (Copper alloy), Iron, Aluminum, and Natural Wood. Perfect for students to physically compare mass, density, and thermal conductivity across metallic and organic materials
• ACCURATE MEASUREMENT CUBES FOR EXPERIMENTS: Each 20mm density block set is machined to standard laboratory specs, providing a consistent surface area for students to practice using calipers, rulers, and graduated cylinders for water displacement tests
• PROTECTIVE STORAGE & TRAVEL CASE: Comes with custom-fitted plastic container. This ensures the density cube set stays dry to prevent oxidation and protects the block kit from damage, making density block set a reliable kit for mobile science teachers and homeschoolers
• IDEAL FOR STEM & PHYSICS LABS: Specifically engineered for classroom demonstrations of Archimedes' principle, buoyancy, and specific gravity. These precision-machined density blocks set help students visualize why equal volumes of different elements possess drastically different weights
• VERSATILE ELEMENT REFERENCE: Beyond density labs, these density cube set serve as excellent reference samples for metal identification and heat capacity experiments. A practical, entry-level element collection for curious young scientists and chemistry labs
