Heat transfers by conduction and materials differ in conductivity. This device demonstrates the diverse thermal conductivity of 5 distinct metals. Place small amounts of the included wax over each metal spoke. Heat the central hub over a Bunsen burner flame and watch the differing rates at which the wax melts. Includes: brass hub; five labeled metal spokes (aluminum, brass, steel, nickel and copper); wax; wood handle mounted on ring with 4 different metals
