| Question | Answer |
|---|---|
| conductor | a material through which electic current passes easily ex: metal |
| insulator | a material through which electric current does not pass easily ex: glass, plastic, rubber |
| closed circuit | a closed path through which electric current passes |
| open circuit | an open path through which electric current does not flow |
| Series Circuit | a circuit that connects several objects one after another so that the current flows in a single path |
| Parallel Circuit | a circuit that connects several objects in a way that the current for each object has its own path |
| magnet | anything that pulls iron, steel, and certain other metals to it |
| magnetism | the force around a magnet |
| magnetic field | the space arond a magnet where magnetism acts |
| pole | a place on a magnet where magnetism is strongest |
| compass | a small magnet that can turn freely |
| generator | a machine that uses an energy source and a magnet to make electricity |
| electromagnet | a magnet made when an electric current flows through a wire |
| When two objects have different electric charges, they | pull together |
| Electric current is the flow of | negative charges through matter |
| Every time you turn on a light, you | close an open circuit |
| When you turn off one lamp, all the lights in the room go off. The electric alliances must be connected to | a series circuit |
| If you connect too manny appliances to one circuit, the wires can | overheat and cause a fire |
| Frayed or broken insulation is dangerous because it can | cause a fire or electric shock |
| You hold the south poles of two magnets near each other. The poles will | repel each other |
| If a magnet is allowed to swing freely, the north-seeking pole will point | north |
| When you push the button on a doorbell, you are | closing a circuit |
| As you rub a balloon on your sleeve, it picks up a _____________ charge | negative |
| If you sprinkle tiny pieces of iron over a magnet, the pattern formed shows a | magnetic field |
| Electric generators have huge electromagnets plus a | power source |
