Electricity is a form of energy that occurs naturally from lightning or is produced in generators through the movement and interaction of electrons. Materials that allow electricity to pass through are called conductors, such as scissors, paper clips, aluminum foil, iron, steel and copper. Materials that do not allow electricity to pass through are called insulators, like cotton, paper, plastic, glass and rubber. The complete path that electricity flows through is called a circuit, which must be unbroken to allow electricity to flow. Electricity can be dangerous if not used properly.
