2  Heat is energy that flows from one object to another.  3 types of heat transfer:  Conduction, Convection, Radiation  Heat moves from a hotter to colder objects.  When heat is added, molecules move faster.  When heat is taken away, molecules move slower.  When a solid gets heated, the molecules expand. When it cools, the molecules contract.  Insulators slow the movement of heat.  Ex. Wool, plastic, wood, fiberglass, and snow.

4  Temperature is the measure of how fast the molecules move.  Heat is the thermal energy that moves those molecules.

6  Conduction- the flow of heat energy from one molecule to another.  Molecules vibrate in solids to pass the energy.  Conductor- material that transmits heat  Some metals are good conductors.  Copper  Aluminum

8  During convection, heat is circulated throughout fluids, such as air and water.  When the liquid/gas molecules heat, they move around more and become less dense. Therefore, they begin to rise.  Wind is a convection current.

10  Radiation is the transmission of heat between 2 objects that are not touching.  Sunlight is a wave of radiant energy that can pass through space.
