Shocking Science
What form of energy is produced when electrons move?
Electricity
What word describes the movement of electrons through a wire?
Current
What do we call the complete loop that electricity must follow to work?
A circuit
What do we call a type of material allows electricity to pass through easily?
Insulator
Which uses more power: a 40-watt bulb or a 75-watt bulb?
75-watt bulb
When you flip a switch and a lamp turns on, what type of energy is flowing through the cord?
Electrical energy
Water flowing through a hose is similar to what in an electrical circuit?
The flow of electrons
When a switch is turned off, is the circuit open or closed?
Open
What type of material blocks the flow of electricity?
Insulator
What is the “push” or pressure that moves electrons through a circuit called?
Voltage
What tiny charged particles move to create electrical energy?
Electrons
If a wire is broken, what stops moving through the circuit?
Electrons
Give an example of a load.
Anything that uses electricity to do work - fan, motor, lightbulb, speaker, oven, etc.
Which conducts electricity better: a paperclip or a wooden stick?
A paperclip
What happens to a bulb’s brightness when voltage increases in a simple circuit?
It gets brighter
A natural example of electricity involving a sudden charge release
Lightning
When the amount of amps increases (goes up) in a circuit, what else is increasing?
The flow or the number of electrons moving through the circuit
What part of a circuit would you add if a bulb is too bright and you want to reduce the current?
reisistor
Why are electrical wires covered in plastic or rubber?
To keep users safe by preventing electrical shock
What increases (goes up) when you use a battery with more voltage?
The force pushing the electrons
Why do devices stop working when electrons cannot move through a circuit?
Without electron movement, there is no current to power devices
Why does an open circuit prevent a device from turning on?
The path is broken and electrons cannot flow
If the load is removed but the wires still connect the battery, what happens?
Electricity flows, but no device uses the energy
What type of material is used in computer chips because it conducts electricity only under certain conditions?
Semiconductor
If two circuits use the same battery but one has more amps, what does that tell you about the electron flow?
More electrons are moving in that circuit
