Heat Transfer
Grade 4 · Science · Energy · New Brunswick, Canada
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).
