15.1
Energy stores and transfers
Energy stores, the four ways energy is transferred, conservation of energy, and wasted energy.
15.2
Conduction and thermal equilibrium
Temperature, hot to cold, thermal equilibrium, temperature and energy, conduction, conductors and insulators.
15.3
Convection and radiation
Convection currents in liquids and gases, infrared radiation, and black and shiny surfaces.
15.4
Insulation
Insulators and trapped air, keeping homes warm, testing insulators, the vacuum flask, and animals.

What this unit covers
Mapped to the KS3 national curriculum (Physics: energy changes, transfers and changes in systems).
| Programme of study | Lesson |
|---|---|
| energy as a quantity that can be quantified and calculated; the total energy has the same value before and after a change | 15.1 |
| comparing the starting with the final conditions of a system and describing increases and decreases in the amounts of energy associated with movements, temperatures, changes in positions in a field, in elastic distortions and in chemical compositions | 15.1 |
| other processes that involve energy transfer: changing motion, dropping an object, completing an electrical circuit, stretching a spring, metabolism of food, burning fuels | 15.1 |
| heating and thermal equilibrium: temperature difference between two objects leading to energy transfer from the hotter to the cooler one, through contact (conduction) or radiation; such transfers tending to reduce the temperature difference: use of insulators | 15.2, 15.3, 15.4 |
