4. infer that nonmetallic objects are not good conductors of electricity. 5. make a binary classification system using the terms conductor and nonconductor. 6. communicate their results by accurately recording their observations. 2. accept responsibility for gathering and returning materials to their prescribed location. The movement of electricity is called current.
Electricity flows when a circuit is complete.
A complete circuit must have a source like a battery, appliances like a lamp or motor to use the electricity and wires to connect the objects. Appliances can be arranged in series. A series circuit has all appliances tied together in one large loop. Materials that allow electric current to flow through without difficulty are called conductors. Most metals like copper, aluminum, gold, silver and brass are good conductors.
