Question | Answer |
A material that transfers heat or electricity well is a ... | conductor |
A path that electricity can move through is a ..... | circuit (circuito) |
A material that does not transfer heat or electricity very well is a .... | insulator (aislador) |
The region of magnetic force surrounding a magnet is called the... | magnetic field |
The buildup of electrical charge on a material is... | static electricity |
The movement of an electrical charge from one object to another is a ... | discharge |
The pull of a magnet is strongest at its .... | poles |
The person who discovered that lightning is a form of electricity found in nature was.... | Benjamin Franklin |
The inventor of the first electric light bulb was...
(at least he got the credit!) | Thomas Edison |
Poles are found at the _____ of a magnet. | ends (extremo) |
An example of a good insulator is... | rubber, plastic |
Rubbing a balloon with a cloth gives it a negative charge. It sticks to the wall because the wall provides a... | positive charge |
The person who discovered that by moving a magnet near a wire electricity could be made; also invented the first transformer | Michael Faraday |
How the poles of a magnet affect each other | like poles repel/unlike poles attract |
The name for the device that turns on or off the current in a circuit | Switch (Interruptor) |
Small pieces of metal (like sand) used to show a magnetic field | Metal or iron filings |
Materials that are generally good conductors | Metal |
Changing energy from one form to another - example, a battery changes chemical energy into electrical energy - example a car changes chemical energy in gasoline to movement of a car - some energy is wasted in the process | Transformation of energy |
A magnet which attracts metals only when electrically activated - made by wrapping wire around a metal nail | Electro magnet |
Shows the location and strength of a magnetic field | Magnetic lines of force |
An electrical circuit that has two or more components that are connected in parallel - One bulb can burn out and the others still light | Parallel circuit |
Any electric circuit having all elements joined in a sequence such that the same current flows through them all - If one bulb (element) burns out, they all stop working | Series circuit |
A circuit that does not allow electricity to flow- open switch- lights off | Open circuit |
A complete electric circuit around which current can flow - the lights are on | Closed circuit |
Energy of a chemical reaction - examples, gasoline burned in a car engine / fire | Chemical energy |
Pulling together | Magnetic attraction |
A battery stores what kind of energy? A ball at the top of a hill was what type of energy? A bicycle gears represent what type of energy? | 1. chemical 2. potential 3. mechanical |
