Science Energyusually ages 11–12

Energy can't be created or destroyed

Explain the principle of conservation of energy (energy cannot be created or destroyed, only transferred between stores), and describe how energy is dissipated as thermal energy to the surroundings in all real processes

How to tell they’ve got it

Tick these off as you see them — no test required.

States the law of conservation of energy
Explains why the total energy in a closed system is always the same even though it changes form
Explains what dissipation means and why it happens in real machines (friction, air resistance)
Gives an example showing why 'wasted' energy is not lost but transferred to the surroundings

Try this together

If your child charged their phone overnight and was asked where the electrical energy goes, could they explain what conservation of energy means — and why the charger gets warm even though that heat isn’t doing any useful work?

Builds on

Naming types of energyages 7–9Explaining conservation of energy and dissipation requires energy store and transfer vocabulary

Energy stores and transfersages 11–12Conservation of energy is a property of energy stores and transfers — the stores and pathways model must be established first

Unlocks

Efficiency, Sankey diagrams, and work doneages 12–13Efficiency calculations quantify how much energy is conserved vs dissipated — conservation and dissipation must be understood first

Power: watts and energy per secondages 12–13Power is the rate of energy transfer — the concept of energy stores and conservation must be understood before rates can be discussed

Reactions That Release or Absorb Heatages 12–13Conservation of energy in physical systems connects to exothermic/endothermic reactions — energy is conserved in chemical systems too
