In successfully completing this unit, the Learner will have		Evidence needed
demonstrated the ability to
1	define the term 'specific heat capacity'	Summary sheet and/or student completed work
2	calculate the amount of energy stored in, or released from, a system as its temperature changes, by applying the equation 'E=mc^2'	Summary sheet and/or student completed work
3	investigate the specific heat capacity of two materials	Summary sheet and/or student completed work
4	define 'power' as the rate at which energy is transferred, recalling and applying the equation from the physics equation sheet	Summary sheet and/or student completed work
5	define 'power' as the rate at which work is done, recalling and applying the equation from the physics equation sheet	Summary sheet and/or student completed work
shown knowledge of
6	the watt as an energy transfer of one joule per second	Summary sheet and/or student completed work
7	the key ways two systems transferring the same amount of energy can differ in power output due to the time taken	Summary sheet and/or student completed work
demonstrated the ability to
8	state that energy can be transferred usefully, stored or dissipated, but cannot be created or destroyed and so the total energy in a system does not change	Summary sheet and/or student completed work
9	explain that only some of the energy in a system is usefully transferred, with the rest becoming ‘wasted’	Summary sheet and/or student completed work
10	give three examples of how wasted energy can be reduced	Summary sheet and/or student completed work
shown knowledge of
11	the relationship between thermal conductivity and energy transferred	Summary sheet and/or student completed work
12	the main way the rate of cooling of a building is affected by the thickness and thermal conductivity of its walls	Summary sheet and/or student completed work
demonstrated the ability to
13	calculate efficiency using the equation from the physics equations sheet, on at least one occasion.	Summary sheet and/or student completed work
