Adult shows one energy transfer (circuit lights, or heat moving to a cooler hand nearby) and names the path. 3. Child traces or describes three energy paths and says what changed. 4. Fresh check: one fresh energy-path description. Record and stop. Done: three energy-path notes with a before/after change. Proof: parent note of examples and results.
