In order for electricity to flow through a circuit, the circuit must be a closed, complete:
Path, so that the electricity can make a complete circle.
Donut, because circuits get hungry.
Wire, made out of rubber.
Solar panel, because circuits only work with the sun.
The circuit on the left is not complete (the light is off) because:
the switch is closed
the switch is open
the battery is missing
the battery is in backwards
The circuit on the right is complete (the light is on) because:
the switch is closed
the switch is open
the battery is hot
the battery is red

the switch is open
the switch is closed
the switch is black
the switch is not there
Circuit "B" is working (it flows), because:
the switch is open
the switch is closed
the switch is black
the switch is not there
What type of circuit is shown in the picture?
Series Circuit
Broken Circuit
Parallel Circuit
Open Circuit
What is missing from this circuit? Why would the light bulbs be off?
The battery, there is no power for the circuit to work.
The switch is open, so the circuit is broken.
The third light bulb, that is needed to complete the circuit.
The wires are not connected properly.
This steel paperclip would allow electricity to flow through it because:
it is a conductor
it is an insulator
it is friendly
it breaks the circuit
This rubber ducky would block the flow of electricity, because:
it is a conductor
it is an insulator
it is yellow
it completes the circuit

What can cause electrons to jump across a gap and cause a spark?
rubbing two coins together
charging a battery
an imbalance of charges between surfaces
True/False: static electricity powers your appliances
True
False
