Worked Solution

CLAIM: The electric fan converts electrical energy to kinetic energy. EVIDENCE: The fan is plugged into the power supply (electrical energy input) and its blades spin (kinetic energy output). REASONING: Electrical energy from the power supply drives the motor in the fan, which causes the blades to rotate and produce movement (kinetic energy).

Correct answer: Electrical energy to kinetic energy
