What is a science experiment that could be used to test the conductivity of different metals and alloys?
I cannot find any info of a science experiment to test it??? i would appreciate alot of help thank you. :D

Conductivity is a measure of how well something conveys electrons. If you build a circuit with a battery and a wire running from one pole to the other, electrons will move through the wire; this can be shown if you have a galvanometer (a meter that measures small electric currents) somewhere in the circuit. If you then break the wire, and place different items across the wire's broken ends, the electric current may or may not flow -- how easy or difficult the item conveys electrons can be measured by the galvanometer and is a reflections of the item's conductivity. The inverse of conduction is resistance; a piece of iron will have high conduction and low resistance; a piece of wood will have low conduction and high resistance. Resistance is measured in the electrical unit of ohms, conduction is measured (in reverse!) in the electrical unit of mohs.
