• Conduction : Transfer of thermal energy through direct contact of particles.
• Convection : Transfer of thermal energy by movement of fluids.
• Radiation : Transfer of energy through electromagnetic waves without particles.
• Thermal Energy Transfer : Movement of heat from warmer to cooler objects.
• Heat : Energy transferred due to temperature difference.
• Temperature : Measure of average kinetic energy of particles.
• Thermal Energy : Total energy of all particles in a substance.
• Conductor : Material that allows heat to pass through easily.
• Insulator : Material that slows down heat transfer.
• Convection Current : Circular movement of fluid caused by heating.
• Less Dense : Particles spread out and rise.
• More Dense : Particles are closer together and sink.
• Fluid : A substance that can flow such as a liquid or gas.
• Ultraviolet : High-energy invisible radiation from the sun.
• Infrared : Invisible radiation associated with heat.
• Visible Light : Radiation humans can see.
• Electromagnetic Waves : Waves that transfer energy through space.
• Absorption : When energy is taken in by a material.
• Reflection : When energy bounces off a surface.
• Emission : Release of energy from a substance.
• Ozone Layer : Atmospheric layer that absorbs most UV radiation.
• Atmosphere : Layer of gases surrounding Earth.
• Gamma Rays : Very high-energy radiation absorbed by the atmosphere.

• R Value : Measure of insulation effectiveness.
• Insulation : Material used to reduce heat transfer.
• Heat Exchanger : Device that transfers heat between incoming and outgoing air.
• Air Current : Movement of air due to temperature differences.
• Draft : Unwanted flow of air that causes heat loss.
• Geothermal Energy : Heat energy from inside Earth.
• Magma : Molten rock beneath Earth's surface.
• Igneous Rock : Rock formed from cooled magma.
• Metamorphic Rock : Rock changed by heat and pressure.
