Question | Answer |
Open Circuit | A brake in the circuit that does not allow electricity to flow. |
Closed Circuit | A complete circuit where electricity can flow. |
Conductor | A material that allows electrons to flow through it easily. |
Insulator | A material that does not allow electricity to flow through it. |
Name three good conductors of heat and electricity. | water, copper, aluminum, steel, gold, silver, etc. |
Name three things that are insulators. | rubber, wood, cloth, plastic, glass, crayon, etc. |
Electromagnet | a temporary magnet that uses an electrical current in a wire to become a magnet. |
What can cause an electromagnet to be stronger? | Adding more of a power source or wrapping more coils around a nail. |
What happens when you add energy such as electricity to an object such as a wire? | It gets hot. |
Switch | An object that opens and closes a circuit. |
magnetic field | The space around a magnet in which the force can be felt. |
attract | to pulls towards an object |
repel | to push away from an object |
What materials would you need to build a circuit? | a power source, a conductor such as a wire, and a receiver or load such as light bulb. |
What would happen if you removed a wire from a circuit? | It would open the circuit because it wouldn't be complete. |
What things are made of atoms? | Everything! |
What travels from atom to atom to make the circuit work? | electrons |
In a complete circuit, what's the purpose of the d-cell battery? | It is the power source |
How can you make a temporary magnet? | You can stroke an object with a magnet several times and it will align the domains of the atoms in the magnet. You can also touch a magnet to steel and it will magnetize the steel. |
True or False? The magnetic field of a magnet can go through various objects. | True |
True or False? The greater the distance between an object and a magnet, the stronger the magnetic field. | False |
True or False? The poles on a magnet that are alike, attract each other. | False |
What is a natural magnet made of iron ore called? | Magnetite |
True or False? All metals are attracted to a magnet. | False |
True or False? All metals conduct electricity? | True |
