This article briefly discusses the heat transfer of radiation, convection, and conduction.  It then explains how using a cooler or thermal insulator reduced the chance of those forms of heat transfer and shows house the make a a DIY cooler.  

Convection in Water

This video shows convection currents in water when it is heated by placing a burner below a flask of water which contains water with a dye in it.

This video discussed radiation.  It points out two main things:  Radiation in the only way heat can transfer through a vacuum and matte black is the best color for emitting and absorbing radiation.
