Vocabulary
Circuits
Conductors and Insulators
100
Balloon A has a positive charge. Balloon B has a negative charge. What will happen?
They will attract each other.
100
???? = a buildup of electric charge on an object
static electricity
100
What's the difference between a series circuit and a parallel circuit?
A series circuit has only one path for the electric charge to follow. A parallel circuit has more than one path for electric charge to follow.
100
What is a conductor?
A conductor is a material that electricity can move through easily.
200
Both of these balloons have a negative charge. What will happen?
They will repel each other.
200
???? - a steady flow of electric charges
electric current
200
What is the difference between an open circuit and a closed circuit?
An open circuit doesn't make a complete loop and won't allow an electric charge to flow.
A closed circuit makes a complete loop and allows an electric charge to flow.
200
What is an insulator?
An insulator is a material that electricity can't move through easily.
300
What is the electric charge of this atom?
Its electric charge is -3.
300
???? - a material that electric charges can't move through easily
300
What will happen if one of the bulbs in this circuit goes out?
The second bulb will stop shining.
300
Which of these materials are conductors?
Silver, copper, gold, steel, and sea water are conductors?
400
What is the electric charge of this atom?
It has a neutral charge. +0
400
???? - a material that electric charges can move through easily
400
What will happen if one of the light bulbs in this circuit goes out?
The other light bulbs will continue to shine.
400
Which of these materials are insulators?
Glass, dry wood, rubber, and diamond are insulators.
500
What would the electric charge of this atom be if it gained 5 electrons?
Its electric charge would be -5.
500
???? - a path on which electric charges can flow
500
What would happen if we flip the bottom switch of the red circuit?
Two light bulbs would light up.
500
James built a circuit and completed it with a rubber duck. Is this an open circuit or a closed circuit? Why?
It's an open circuit because rubber is an insulator, so the electric charge can't flow.
600
What would the electric charge of this atom be if it lost 7 electrons?
Its electric charge would be +4.
600
What is this? Be specific.
It's a series circuit.
600
What would happen if we flip the bottom switch of the green circuit?
Nothing would happen because there's no battery.
600
James built a circuit and completed it with a metal key. Is this an open circuit or a closed circuit? Why?
It's a closed circuit. The key is a conductor, so it allows the electric charge to flow.
700
Samantha rubs the balloon on her cat's fur. Describe what is happening in the picture. Use the words electrons, negative charge, positive charge, and attract in your answer.
When Samantha rubs the baloon on the cats fur, electrons move from the fur to the balloon. The balloon then has a negative charge, and the cat has a positive charge. Because the cat and the balloon have an opposite charge, that cat's fur and the balloon attract.
700
What is this? Be specific.
It's a parallel circuit.
700
What would happen if we flip the bottom switch of the blue circuit?
Four bulbs would light.
800
What would happen if we flip the bottom switch of the purple circuit?
Nothing would happen because the bulbs should already be lit.
