insulators and conductors

water is a insulator.

• true

• false

which is NOT an insulator.

• wool

• glass

• copper

• plastic

what is a conductor?

• materials that

• material that does NOT transfer energy.

• materials that transfer energy.

• materials that are connected to circuits.

in a parallel circuit if one of the light bulbs burn out the rest

• can still light up

• stop the flow of electricity

• will go out

• of the light bulbs burn out also

which one is an insulator?

• mechanical pencil

• plastic

• silver

• copper

an insulator is a material that:

• slows electrical energy and allows thermal energy to pass

• transfers electrical energy and slows thermal energy

• transfers thermal and electrical energy

• slows thermal and electrical energy from transfering

what is NOT an example of an insulator in the kitchen?

• a wooden spoon

• pots and pans

• a plastic measuring cup

• an oven mitt

what is Alfredo Moser's invention?

• bleach

• light bulb made in a water bottle

• voltage

• electricity

mittens help keep your hands warm in winter because:

• they are fuzzy.

• they are conductors of electrical energy.

• they are conductors of heat.

• they are insulators.

the metal copper is there to:

• provide an insulator for energy to flow from one place to another.

• provide a conductor so slow the flow of energy.

• provide a conductor for energy to flow from one place to another.

• provide an insulator to slow the flow of energy.
