This part of a circuit provides the energy that allows electricity to flow.
What is a battery?
If a bulb lights when testing a material, the material is this.
What is a conductor?
This type of electricity is the buildup of charge on an object.
What is static electricity?
A magnet that needs electricity to work is called this.
What is an electromagnet?
Changing thin cardboard to thick cardboard helps test this.
Does material thickness affect a magnetic field?
These connect parts of the circuit and allow electricity to travel.
What are wires?
Materials that do NOT allow electricity to flow are called this.
What are insulators?
Electricity that flows through wires is called this.
What is current electricity?
This type of magnet is permanent and does not require power.
What is a bar magnet (permanent magnet)?
Repeating a test with different materials helps ensure this.
What is reliable evidence (accurate results)?
When this is open, the light bulb will not turn on.
What is a switch?
Aluminum foil is most likely this type of material in a circuit.
What is a conductor?
Current electricity requires this type of circuit.
What is a closed circuit?
A magnet that can be turned on and off is best for picking up objects and dropping them elsewhere.
What is a temporary magnet (electromagnet)?
Observations that support a claim are called this.
What is evidence?
Glass is an example of this type of material that prevents electricity from flowing.
What is an insulator?
The best way to test materials is to connect them between open wires and observe this.
Whether the bulb lights.
Rubbing a comb with wool and attracting paper is an example of this.
What is static electricity?
Permanent magnets are useful in places without this.
What is a power supply (electricity)?
The best conclusion when a bulb lights is that the tested material is this.
What is a conductor?
A circuit must be this for electricity to flow and light a bulb.
What is closed (complete)?
Plastic and cardboard usually allow magnetic fields to pass because they are this type of material.
What are nonmagnetic materials?
The movement of electric charge through a wire is known as this.
What is electric current?
Iron and steel are attracted to magnets because they are this type of material.
What are magnetic materials?
Comparing two magnets by experimenting helps determine their best this.
What is use (application)?
