  1. Grounding • Grounding = connects material directly to the ground, or earth. • The Earth is huge!! It can accept or give up many electrons without any significant change in its charge.

  2. The symbol for ground is: • Grounding prevents serious accidents! The third prong on plugs is connected to the ground.

  3. Conductors, Insulatorsand In-Between • Conductor: materials that allow charges to move freely e.g. Aluminum, copper, iron

  4. Insulator: materials that do NOT allow charges to move freely e.g. cotton, wood, rubber

  5. In-Between: materials that allow charges to move LESS freely than conductors and MORE freely than insulators e.g. Carbon, human body, salt water
