Conduction in science is when energy moves from one place to another place by touch. Electrical conductors and heat conduction are the two most important kinds. In heat conduction, the heat energy travels from the hot point to a cold point. Something that energy can easily move through is a good conductor. Metal is a good conductor. An insulator is a poor conductor. An example is rubber. Energy cannot move quickly through an insulator. Plastics are insulators. Some materials, such as glass, are conductors for heat but not electricity.
