U5D1: Conductors and Insulators

A _ is a material that allows electricity or heat to easily flow through it. conductor insulator rubber supressor Materials that block the flow of electricity or heat are known as - _. conductor insulators metallic dividers Sort it out! Look at each of these common items and separate them into categories by insulators or conductors. Conductor penny key paper clip quarter door knob copper wire Insulator paper toothpick plastic fork rubber band glass tape Most objects that conduct electricity or heat are made from this material. Metals Plastics Wooden Cotton The outside of electrical wires often have a layer of insulation to protect the user from being shocked. This protective layer is often made from - flexible woods rigid metals flexible plastics rigid glass Match the term to the best definition or description of the word's meaning. conductor allows electricity to easily flow material what an object is made of metallic an object that is made up of metals insulator blocks the flow of electricity properties characteristics of materials Sort it Out! Separate the conductors from the insulators. conductors Insulators How can you tell if the object connected in this simple circuit is a conductor or insulator? The bulb will not light if it is a conductor The bulb will light if it is a conductor The bulb will light if it is an insulator none of these is correct What distinguishes a conductor from an insulator? the amount of electrons present the amount of neutrons present the rate that neutrons travel through material the ease of flow of electrons through the material Which of these is not a good electrical insulator? wood rubber gold glass
