Conductors and Insulator

Today in science  we explored conductors and insulators. A conductor is something that lets electricity flow through an object. An insulator is something that stops electricity from flowing through it. Materials which did not conduct electricity were rubber, wood and plastics so they are insulators.  All the metals objects

we tested lit the bulb so metal is a conductor. From watching a short clip we also learned that although all metals conduct electricity, some are better than others.  Good examples are silver, copper and aluminium.
