Key Idea.
Section 1
Reasoning about Energy Chains
The logical sequence of events in a system is known as the chain of energy. Identifying this chain maps the entire path from start to finish.
The logic begins with the source (Human Kinetic Energy). It then identifies the mechanism of interaction (Generator). Finally, it points to the result in the receiver (Battery Potential Energy). A complete explanation includes every link in this chain.
Section 2
Writing a Scientific Explanation
A strong scientific explanation clearly states a claim backed by evidence. Precise vocabulary—transfer, convert, and store—defines the mechanism.
The explanation functions as a coherent narrative: "The energy originates in the source, transfers to the capture device, converts to electricity, and stores in the battery."
