| Electric field | A region around a charged object where the objects electric force is exerted on other charged objects | |
| Electricity | The interaction between electric charges | |
| Static electricity | The build up of charges on an object | |
| Electrical discharge | The loss of static electricity as electric charges transfer from one object to another | |
| Electroscope | An instrument that can detect an electric charge | |
| Particle Protons Neutrons Electrons | location in the atom in the nucleus in the nucleus in the outside shell | charge positive neutral negative |
| What is the rule that all charges behave according to | the rule that all charges behave according to is that opposites attract | |
| Method friction induction conduction | Example rubbing an object on your hair rubbing an object on your hair and then holding the object to the wall rubbing a rod in a wool cloth and then touching the knob with the rod | |
| Explain why a persons hair rises when their hands are placed on a Van de Graff generator | a persons hair rises when their hands are placed on a Van de Graff generator because the generator creates a huge build up of static electrical charge on the shiny metal dome | |
| Explain why the metal leaves in an electroscope separate when the metal ball is touched by a charged rod | the metal leaves in an electroscope separate when the metal ball is touched by a charged rod because when you charge a rod and then you touch the metal ball the negative charge will transfer from the rod to the metal leaves to make the leaves split | |
| What is lightning? What is thunder? Explain how lightning can strike something on the ground | Lightning is an example of a huge spark of static electricity. Thunder is a loud rumbling or crash | |
