 Copy the following vocabulary words and definition in notebook.
 1. Heat Energy - Heat energy is a form of energy that is present in the molecules and atoms of an object. The motion of atoms and molecules results in heat energy.

 2. Conduction - Conduction is heat transfer through direct contact. When adjacent atoms vibrate or exchange electrons, heat energy is transferred between them. EX: Heating a pot on a stove

 3. Insulator - A material that reduces the rate of heat transfer by limiting the amount of conduction and/or convection that occurs. Prevents heat moving from one place/object to another.

 4. Conductor - A material that allows heat to be transferred through it
