Heat Transfer
Grade 4 · Science · Energy · Virginia, USA
Lesson Summary
Heat always moves from warmer objects to cooler objects. It can travel by conduction, convection, or radiation.
Explanation
Conduction is heat moving through direct contact, like touching a hot pan. Convection is heat moving through liquids or gases in a circular flow, like warm air rising from a heater. Radiation is heat traveling through empty space as waves, like warmth from the sun. Understanding heat transfer helps explain everyday things, like why a metal spoon gets hot in soup (conduction) or why the upstairs of a house is warmer than the downstairs (convection).
