Station 1: Conduction
Observation: The copper's wax melted first, followed by the aluminum, and the zinc's melted last.
Real Life Example: When a metal pan is placed onto a stove top, the pan becomes hot once the heat is turned on.

Station 2: Convection of a Liquid
Observation: The longer the hot water was in the beaker of cool water, the warmer the beaker's water became.
Real Life Example: When you boil water, the heat from the burner heats the water on the bottom causing it to rise. The cooler water goes to the bottom, and a cycle is made.

Station 3: Convection of a Gas
Observation:
Real Life Example: In a hot air balloon, the air is heated and rises. The air gets trapped by the balloon, causing it to rise. When the pilot wants to descend, he releases some of the hot air and cool air takes its place.
Station 4: Radiation
Observation:
Real Life Example: When you hold your hand next to a light-bulb when it is turned on, you can feel the heat from it without touching it.

Thermal contact - In heat transfer and thermodynamics, a thermodynamic system is said to be in thermal contact with another system if it can exchange energy through the process of heat.
Specific heat - the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
Insulator - a substance that does not readily allow the passage of heat or sound
Conductor - a substance, body, or device that readily conducts heat, electricity, sound, etc.
