How did you find out if an element is a good conductor?

• it lit up a light bulb

• hit it with a hammer

• bubbled in the presence of acid

• turned black

ductile means...

• can be made into wire

• can be bent or hammered

• can light up a light bulb

• it's shiny

copper can be used to make statues like the statue of liberty

• therefore copper is malleable

• therefore copper is ductile

• therefore copper is shiny

• therefore copper is a conductor
