| Electrically neutral | When the number of protons and electrons are equal, canceling each other out. |
| Static electricity | The transfer of electrical charges from one place to another. |
| Conductors | Materials, such as metals, that allow the easy flow of electrons. |
| Insulators | Materials, such as plastic, that do not allow the easy flow of electrons. |
| Induction | Charging and transferring of electrons without touching, so at a distance |
| Conduction | Charging and transferring of electrons by touching two like materials |
| Friction | Charging and transferring of electrons by touching of two different materials |
| Lightning | The static discharge that occurs between charged clouds and the charged ground. |
| Thunder | The aftermath of lightning, where heat from the discharged electrons causes air to expand rapidly, producing sound waves. |
| Current electricity | The type of electricity that moves along a path |
| Series ciruit | Single loop of electron flow. |
| Parallel circuit | More than one path for electrons to flow. |
| Current | Flow of electricity around a circuit |
| Direct Current | A path of electron flow in one direction |
| Alternating Current | A path of electron flow which changes directions often. |
| Ammeter | Measures current |
| Amp | Unit for measuring current |
| Voltage | The gain or loss of energy as electrons pass through a component |
| Volt | Unit for measuring voltage |
| Power | energy used by component per second, measured in watts |
