Three cards build up one at a time: heat moves from a warm hand into an ice cube until it melts (conduction), a heater warms the air and the warm air rises to dry wet mittens (convection), and the Sun's heat travels in rays across empty space to Earth (radiation). The video ends with each card pulsing in turn and a one-line recap: heat moves by conduction, convection and radiation.

Transcript
What the lesson says
How does heat move from one place to another?
Heat moves in three main ways.
In conduction, heat moves by touching.
When you hold an ice cube, heat moves from your warm hand into the cold ice.
The ice warms up and melts.
In convection, moving air carries heat.
A heater warms the air just above it.
The warm air rises and dries the wet mittens hanging above.
In radiation, heat travels in rays.
The Sun's heat travels across empty space to reach Earth.
Nothing has to touch, and no air is needed.
So heat moves by conduction, convection and radiation.
