What is a conductor? - A material that lets electricity flow easily, like metal., What is an insulator? - A material that does not let electricity flow easily, like rubber or plastic., What is electricity? - A type of energy caused by the movement of electrical charges, What is static electricity? - A build-up of electric charge on the surface of an object, usually from rubbing two materials together., What is current electricity? - A steady flow of electric charge through wires or other materials, What is a proton? - positively charged particles found in the center of an atom., What is a neutron? - particles with no charge that are also found in the nucleus., What is an electron? - negatively charged particles that move around the shell, What is a resistor? - a part of a circuit that slows down the flow of electricity. It changes some of the electrical energy into heat or light., What is a circuit? - A closed loop that electricity follows, What is a closed circuit? - A circuit with no breaks that lets electrons flow, What happens in an open circuit? - Electrons stop because the path is broken, What is a switch in a circuit? - A tool that can open or close a circuit to start or stop the flow of electricity., Explain why charges attract or repel? - Opposite charges attract and like charges repel, What protects homes from electrical fires? - Safety devices like circuit breakers and fuses by stopping flow of electricity when there is too much current, What are examples of good conductors? - human body and copper, What is difference between a conductor and an insulator? - A conductor allows energy to pass through and an insulator does not, If 2 charges repel the charges must be____________ - like charges, All matter is made up of  - tiny particles called atoms, Atoms are made of ___________________ - Protons (+), neutrons (0) and electrons (-), What is difference between current electricity and static electricity? - Static electricity is the buildup of electric charges and current electricity is continuous flow, What is an example of static electricity? - Balloon sticking to wall, What is an example of an insulator? - wood, What happens when electrical charges build up in clouds? - discharged as lightning, A neutral object has - equal amounts of postive and negative charges, Describe series circuit - All parts are connected one after another in a single path. If one part stops working, the whole circuit breaks, Describe parallel circuit - Each part has its own path to the power source. If one part stops working, the others still work. Like electrics in our house, What does a resistor do? - resistors help protect things like light bulbs, phones, and computers from getting too much electricity too fast,, What are 2 types of current? - AC and DC, Explain DC (Direct Current) - It comes from a battery, which has a negative end (–) and a positive end (+). Electrons can ONLY flow from the negative side to the positive side. The direction never changes., Explain AC (Althernate Current) -  AC is electricity that travels back and forth. That means electrons are moving back and forth really fast., What do safety devices like circuit breakers and fuses do? - They stop electricity from flowing when too much current is in the circuit to protect it from overheating or fires.,
