Static Electricity
This phenomenon causes your hair to stand up when you pull off a wool hat in the winter.
What is Static Electricity?
This metal, often found in coins, is an excellent conductor of electricity.
What is copper?
This device controls the flow of electricity in a circuit, allowing it to turn on or off.
What is a switch?
The two ends of a magnet where the magnetic force is strongest are called these.
What are the poles?
An electromagnet requires this to produce a magnetic field.
What is an electric current?
This type of charge do individual hairs gain when they repel each other after rubbing against a wool hat.
What is the same charge?
Materials like rubber, glass, and plastic are examples of this type of material that doesn’t allow electricity to flow easily.
What are insulators?
This material is commonly used for electrical wires because it is a good conductor.
What is copper?
Opposite magnetic poles do this when brought near each other.
What is attract?
Wrapping a wire around this metal object can create a stronger electromagnet.
What is an iron nail?
Rubbing a balloon on your head transfers these particles from your hair to the balloon.
What are electrons(negative particles/charges)?
This everyday object in your classroom can conduct electricity.
What is a paperclip?
What is a staple?
Etc.
In order for electricity to flow and a light bulb to light, the circuit must be this.
What is closed?
This invisible force field surrounds a magnet and allows it to attract objects.
What is a magnetic field?
You can increase the strength of an electromagnet by doing this to the wire.
What is increasing the number of coils?
When socks stick together after being in the dryer, it’s due to this buildup of electric charge.
What is static electricity?
Electricity moves through conductors because they have free-moving particles called these.
What are electrons?
This part of the circuit provides the energy needed to power devices like light bulbs.
What is the battery?
This natural mineral is known for its strong magnetic properties and was used in early compasses.
What is lodestone?
Unlike regular magnets, electromagnets can be turned on and off by controlling this.
What is the electric current?
This small shock you feel when touching a doorknob after walking on carpet is caused by this type of discharge.
What is static discharge?
This property makes metals like aluminum and silver excellent conductors of electricity.
What is low resistance? Strong Conductor?
A material that resists the flow of electricity, like rubber or plastic, is called this.
What is an insulator?
When a magnet breaks in half, it forms this many new magnetic poles.
What are four? (Each piece has a north and south pole.)
This type of crane uses electromagnets to move heavy metal objects, like cars.
What is a magnetic crane?
