CONCEPT 1
ENERGY FROM FUEL AND FOOD
KNOW >
I know that fuel is a source of energy and that energy is measured in joules (J).
APPLY >>
I can apply my knowledge of fuels to explain how food is a fuel and that it stores energy which we can measure in kilojoules (kJ).
EXTEND >>>
I can extend my knowledge to explain that energy is stored in various ways and it can be transferred from one store to another store.
CONCEPT 2
ENERGY USE IN THE HOME
KNOW >
I know that electricity is a way to transfer energy and that appliances with a higher power transfer more energy each second.
APPLY >>
I can apply my knowledge to calculate the power of an appliance, energy used or time using the equation: power = energy transferred ÷ time taken.
EXTEND >>>
I can extend my knowledge to use the equation power = energy transferred ÷ time taken, with units of kilowatts, hours and kilowatt-hours.
CONCEPT 3
ENERGY RESOURCES
KNOW >
I know that electricity can be generated by different methods and I can list these into groups called renewable and non-renewable.
APPLY >>
I can apply my knowledge of generating electricity and present advantages and disadvantages of each method.
EXTEND >>>
I can extend my knowledge of generating electricity to use evidence to make decisions about a suitable choice of method.
