In the order the concepts build on each other.
- Heat flowLockedHeating something raises its temperature. Heat always moves from a hotter thing to a colder one: from hot tea into the cup and the air, from your warm hand into an ice cube. It keeps moving until the two are equally warm. Cold doesn't move; heat moves out.Opens after: Temperature
- Heat conductors and insulatorsLockedSome materials let heat through quickly: metals, which is why pots and pans are metal. They are heat conductors. Others let heat through slowly: wood, plastic, cloth, wool and air. They are heat insulators. We use them for pan handles, flasks, warm clothes and thick curtains, to keep heat where we want it.Opens after: Heat flow
