Guiding Questions: What is hot?
How have you experienced a heat transfer to you?
How have you experienced a transfer of heat away from you?
Heat energy flows from objects that are higher energy to objects with lower amounts of energy. If there is no heat source in a glove, the thermometer does not heat up.

Resource #5 (Simulation)
- thermal energy - Heat energy
- atom - smallest particle of matter
- molecules - two or more atoms joined together
- particles - A very small piece or part of matter
- radiate - to send out rays; to beam or shine
- radiation - Energy that is radiated or transmitted in the form of rays or waves or particles.
- conduction - The direct transfer of heat from one substance to another substance that it is touching.
- convection - the transfer of heat through a fluid (liquid or gas) caused by molecular motion
- thermal radiation - transfer of thermal energy by waves that can travel through air or across space
- heat - The energy transferred between objects that are at different temperatures
- temperature - A measure of the average energy of motion of the particles of a substance.
- insulator - A material that does not allow heat or electrons to move through it easily.
- conductor - A material that allows heat and electricity to pass through it.
- heat transfer - the movement of energy from a warmer object to a cooler object
- kinetic energy - energy of motion
