3. There are two categories (types) of electricity: Current electricity – Current electricity can be used by people. when electrons flow through a circuit.
4. There are two categories (types) of electricity: Static electricity – when electrons build up on an insulator (rubber, clothing, non-metals) causing an imbalance. The “charge” of static electricity is sometimes discharged (balanced) by a spark. This type of electricity is not used much by people, but can be fun (and sometimes dangerous).

11. When more negatively charged electrons are on an object it has a negative charge. If electrons have been taken away, the object will be have a positive charge because it is out of balance toward the positive protons.
12. Your body is an object that can become unbalanced with a negatively charge when you shuffle your shoes on a carpet. The spark that jumps from your hand to the doorknob balances your static charge. You have to walk on the carpet some more to get another spark.
