Things can warm up or cool down (heat transfer) in three ways: conduction, convection, and radiation. Here is a brief review of which is which!

Conduction: heat transfers through touch, like melting butter in a pan.

Convection: transfers heat through air or liquid currents, like the heat from a blow dryer, or like the heat that comes out of the air vents in a car to warm you up.

Radiation is heat transfer through invisible waves, like the sun warming us up.

Can you think of any examples of heat transfer?
