4.1 Energy transfer and electricity |
| describe how energy can be stored, e.g. food, fuels and electrical cells
| use a simple model of energy transfer to describe common observations
|
| describe how energy is transferred in simple contexts such as heating and cooling, food chains and simple circuits
| explain why quantitative measures of energy transfer should also be considered when making informed decisions, e.g. building wind farms
|
| recognise that quantitative measures of energy transfer are needed to inform decisions, e.g. about lifestyles
| explain how electricity is generated using a variety of energy resources
|
| describe how energy stored in a range of energy resources, e.g. food, biomass, oil, gas, wind and waves, can be usefully transferred
