What is a conductor?
What is an insulator?
any material that stops energy (electric current) from flowing
What does flow mean?
What is a circuit?
the pathway through which electrical current flows; can be connected by wires, batteries, switches, and lightbulbs
What is an electrical current?
a flow of electricity through a conductor
To show work an object has to
move
True or false: For a circuit to work, there must be an incomplete path with an open switch.
FALSE: There must be a complete path that must have a closed switch.
Current flows through what material?
a. plastic
b. air
c. metal
metal
What is a series circuit?
A circuit in which the current flows through only one pathway

A. hitting a volleyball
You are adding force to the volleyball which will make it move.
A series circuit with a light and a bell is missing a battery (energy source) will this circuit work ?
No-there needs to be an energy source to allow complete path for electrons to flow.
When a light bulb is on, does that mean the circuit is open or closed?
Closed
