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
