Circuits
This is the flow of electric charges that moves in an unbroken path
What is an electric current?
These are materials through which an electric current can pass.
What are conductors?
Early scientists most likely saw a discharge of electricity for the first time while observing this.
What is a lightning storm?
These are temporary magnets, NOT permanent magnets.
What are electromagnets?
In this type of circuit, electricity has only one path to follow.
What is a series circuit?
This is the pathway taken by an electric current.
What is a circuit?
What are insulators?
These are examples of non-renewable sources of energy.
What are fossil fuels? (Coal, Natural Gas, Oil)
This term means 'to push away'
What is repel?
In this type of circuit, electricity has more than one path to follow.
What is a parallel circuit?
This type of circuit is a complete circuit where everything is connected and electricity can easily flow through it.
What is a closed circuit?
Nails, paperclips and aluminum foil are examples of this.
What are metal objects or conductors?
What are solar, wind, hydro and geothermal?
This is the invisible force field around every magnet.
What is a magnetic field?
This is a material that cuts down the flow of current, but does not stop it.
What is a resistor?
This type of circuit is an incomplete circuit where there is some part that is not connected and electricity cannot flow through it.
These are two or three examples of insulators.
What are plastic, wood or glass?
This is the unit used to measure the energy used by an appliance (like a microwave) in a certain amount of time.
What is a watt?
All magnets have these two types of poles.
What are north and south poles?
These are the basic materials needed to make a circuit.
What are a power source (battery or outlet), wires and a light bulb?
This is a device that is used to open and close a circuit easily without connecting and disconnecting the wires.
What is a switch?
This is the name of the crackle you hear and feel when you touch a doorknob after rubbing your feet across a carpet.
What is static electricity?
A battery make a motor run by changing electrochemical energy into this type of energy.
What is mechanical energy?
To make an electromagnet, a conductor could be coiled around this.
What is an iron or steel rod or nail.
This person invented the light bulb.
Who is Thomas Edison?
