Definitions
The flow of electricity is called this.
What is electric current?
Name one more conductor: gold, iron, or aluminum.
What are metals?
Name one insulator: glass, wood, or paper.
What are insulators?
Wires use conductors to carry this.
What is electricity?
Which is a conductor: copper, plastic, or rubber?
What is copper?
Conductors have these particles that move freely.
What are free electrons?
Water can conduct electricity because it contains this.
What are ions?
Dry wood is usually this type of material.
What is an insulator?
Rubber gloves help prevent this.
What is electric shock?
Which is an insulator: glass, gold, or aluminum?
What is glass?
Insulators have very few of these particles
What are free electrons?
True or False: Plastic is a conductor.
What is false?
These materials protect us from electric shock.
What are insulators?
A plug has a fuse to stop too much of this.
What is current?
True or False: Humans are conductors.
What is true?
Conductors have these particles that move freely.
What are free electrons?
Water can conduct electricity because it contains this.
What are ions?
Dry wood is usually this type of material.
What is an insulator?
Birds don’t get shocked because they are not touching this.
What is the ground?
Which allows electricity to flow easily?
What is a conductor?
Insulators have very few of these particles.
What are free electrons?
True or False: Plastic is a conductor.
What is false?
These materials protect us from electric shock.
What are insulators?
Appliances use both conductors and insulators for this reason.
What is safety?
Which blocks electricity?
What is an insulator?
