Conductors- are materials that freely allow the flow of electrons with very little resistance

Semiconductors- do not allow electrons to flow freely but do not directly stop them either

Insulators- are materials that greatly impede or stop the flow of electrons with very high resistance

All of the vocabulary words are all related because each one either has flow or no flow. They all explain how electricty flows

Conductor= Water, Iron, Copper

Semiconductor= Silicon( Used in computer chips)

Insulators= Glass, Dry air, And rubber
