Heat one end of a copper bar and the heat will conduct through it to the other end.
I believe that this is due to the transmission of "vibrancy" in the heated atoms to the non heated ones, as they "share" their energy.
Factors influencing the rate of conduction are:
temperature difference
length
cross-sectional area
material
The best ordinary metallic conductors are (in decreasing order) silver, copper, gold, aluminum, beryllium, and tungsten.

There are only three: Conduction, convection, and radiation.
Conduction requires physical contact between the masse transfering thermal energy
Convection requires the existance of some 'working fluid' (such as air or water) which acts as a transport medium between the two masses.
Radiation takes place through the emission of electromagnetic radiation from --any-- mass which is not at a temperature of 'absolute zero' (0 kelvins)

I hate to just give an answer to something that looks like a homework question.
Why not look up "conduction" in the dictionary. It's a simple concept. I'm sure that'll give you what you need to come up with your own examples. good luck
