Explanation
Stores describe how energy is associated with a system before and after a change. Pathways describe how it crosses between systems. A motor does mechanical work on a load; a circuit does electrical work on a heater. Radiation transfers energy from an emitting source to an absorber.
Concepts, equations and units: Mechanical work, electrical work, heating and radiation pathways; J. Sound can transfer energy by waves.
Prediction, demonstration and game exercise
Predict, observe, explain
Show a lift, lamp and heater; add arrows only while transfer occurs; explain heating as transfer caused by temperature difference.
Planned learner game exercise
Connect labelled arrows between stores through a lift, lamp and heater; include surroundings.
Independent practice
Write two short causal explanations and identify where the battery chemical store decreases.
Original practice example · Shared
A battery drives a motor lifting a load. Trace the useful transfer.
Show working and model answer
Working / reasoning
Chemical store of battery → electrical work to motor → mechanical work → gravitational store of load–Earth system.
Answer
The useful endpoint is an increased gravitational energy store; surroundings also gain dissipated energy.
Exit check and success criteria
Two accurate transfer chains with both endpoints and a valid pathway.
During practice, compare the prediction with evidence and give an error-specific prompt. The exit item uses a fresh context or fresh values, answered independently.
Misconceptions, practical links and mastery
Check these misconceptions
A lamp does not store light energy; energy transfer is not charge transfer.
Practical preparation
Optional battery lamp/heater observation; safe school equipment.
Virtual preparation and revision only. Required hands-on activities and school records remain separate.
Proposed mastery
0: not yet evidenced. 1: supported. 2: independent exit criteria met. 3: successful changed-context transfer. Advance at 2; revisit with fresh retrieval. These are not GCSE grades.
