This Heat Conductivity Ring (Conductometer) is designed to demonstrate thermal conductivity in various metals. The brass hub holds five labelled spokes-aluminium, brass, steel, nickel, and copper-each with wax applied. When the centre is heated, the wax melts at different rates, showing how heat transfers through each material.Educational Benefits: Demonstrates differences in thermal conductivity across metals. Supports inquiry into heat transfer, particle theory, and thermal energy. Encourages prediction, observation, and comparison during experiments. Classroom Ideas: Heat the central hub and observe melting patterns in wax. Rank metals by heat conductivity based on observed results. Integrate into thermal physics lessons alongside insulation materials. Specifications: Includes: Brass hub, 5 metal spokes (labelled), wax, wood handle, instructions Spokes: Aluminium, brass, steel, nickel, copper Requires: Alcohol burner (not included) Safety: Gloves and goggles recommended
