Which of these is an insulator? Choose 2.

• iron nail

• plastic straw

• steel wire screen

• yarn

Which of these is a conductor? Choose 2.

• iron nail

• plastic straw

• steel wire screen

• yarn

Which materials will NOT allow electricity to flow through?

• circuit

• insulator

• conductor

• electricity source

A circuit with two or more pathways for electrical current to flow

• parallel circuit

• series circuit

• open circuit

• conductor

Electricity flow from the ____ end of the battery to the ____ end of the battery

• positive, negative

• negative, positive

• north, south

• south, north

Any material that electricity will flow through

• series circuit

• conductor

• insulator

• lightbulb

Two bulbs are connected to a battery in a series circuit. Both bulbs are lit. A few minutes later, one of the bulbs burns out. What will happen to the other bulb? 

• The other bulb will no longer be lit because the circuit will be incomplete

• The other bulb will glow more brightly because the amount of electricity it receives will increase

• The other bulb will remain lit at the same brightness

• The other bulb will remain lit but will not flow as brightly

What is a closed circuit?

• a connection of components which prevents electricity from flowing

• a circular path that electricity is unable to travel through

• the complete path of an electrical current

• an interrupted path of electricity
