A Peek Inside the Lesson
This is the real lesson text your child hears, read aloud by a friendly voice.
Three Ways Heat Moves
Heat always moves from hotter things to cooler things.
Conduction: heat passes through touching materials, like a hot pan handle.
Convection: warm liquids and gases rise and cool ones sink, making currents.
Radiation: heat travels as waves, even through empty space, like sunlight.
Conductor Race
Thermal conductors let heat move through them quickly. Metals are great conductors.
Insulators slow heat down. Wood, plastic and air are insulators.
That's why pan handles are often made of plastic or wood!
Keep It Hot
Good insulation keeps hot things hot and cold things cold.
Trapped air is a great insulator. Wool and foam are full of air pockets!
Shiny foil reflects heat radiation back.
