Conduction: transfer of heat through direct contact, metal spoon in hot soup, ice melting in your hand, hot sand burning your feet, burning your tongue drinking hot coffee, cooking popcorn on a stove, sleeping under a heated blanket, straightening your hair with a flat iron, putting a marshmallow directly in the fire, Convection: transfer of heat through currents caused by the warming and cooling of liquids and gases, boiling water causing macaroni to rise and fall, warm air rising and cool air sinking, warm water rising and cool water sinking, hot air balloon rising, steam rising from a cup of coffee, moving wind or ocean currents, the air in your basement being colder than the air in your attic, an oven cooking a turkey, Radiation: transfer of heat through electromagnetic waves, the Sun heating the inside of a car, a blacktop parking lot getting hot on a summer day, a huge rock gets so hot from the sun that you can't sit on it, roasting a marshmallow over a flame, feeling the warmth from a fire, getting a tan from laying in the Sun, heat given off by a light bulb, cooking popcorn in a microwave,
