A continuous flow of negative charges creates an electric....
What is a current?
100
The pathway taken by an electric current.
What is a circuit?
100
Magnets are attracted to these kinds of materials.
What are metals?
100
The lines of force extending from the center and the poles create this.
What is a magnetic field?
100
Name the item used in Ben Franklin's discovery that lightning was a form of electricity reaching the ground.
What is a kite?
200
The negative charges in atom.
What are electrons?
200
This kind of circuit is when there is only one pathway for the current to flow. When there is a break or gap, no electricity will flow.
What is a series circuit?
200
These are the ends of the magnet where the force is the strongest.
What are the poles?
200
The magnetic field created from the Earth's core help create a straight pointing north of one of these.
What is a compass?
200
These objects can be attached to buildings to create a direct path for lightning to reach the ground.
What are lightning rods?
300
Electrical energy easily moves through materials like metals.
What are conductors?
300
In this kind of circuit, there are two or more pathways for electricity to flow which means when there is a break or gap everything does not necessarily stop working.
What is parallel circuit?
300
Like poles will do this when two magnets come into contact with one another.
What is repel?
300
A current flowing through a wire creates a magnetic field. Wrapping a wire around certain iron-bearing metals such as an iron nail help to create a closed circuit is an example of one of these.
What is an electromagnet?
300
This gentleman did not discover electricity but that electricity could be discharged to the ground in a thunderstorm.
Who is Ben Franklin?
400
Materials such as rubber, plastic, and wood do allow the flow the electricity.
What are insulators?
400
These kinds of circuits allow the movement of electrical energy to flow.
What is a closed circuit?
400
This happens when two magnets with unlike poles match up.
What is attract?
400
A large scale electromagnet in a junkyard may help to this.
What is to help separate large scraps of metal?
400
This man helped the world to see in the dark by inventing the light bulb.
Who is Thomas Edison?
500
Rubbing certain materials together creates this. Lightning is an example of this in the atmosphere.
What is static electricity?
500
These kinds of circuits prevent the movement of electrical energy to flow.
What is an open circuit?
500
These are two of the three materials that magnets are attracted to. Objects containing these metals will stick to magnets.
What are cobalt, iron, and nickel?
500
A doctor might use an electromagnet do this.
What is to remove metal splinters from a person's body?
500
Michael Faraday's invention of this help to revolutionize the rest of America.
