Circuit Rescue
Electric current flows only around one complete, unbroken loop; a switch controls that loop but is not the same as a broken wire, and every component in a series circuit shares the same route.

What your child will figure out
- Predict whether a lamp will light by tracing a complete route from the battery and back.
- Repair one or more wire gaps and use the resulting current flow as visible evidence.
- Distinguish an open switch from a broken wire by observing where a circuit trace stops.
- Transfer complete-loop reasoning to two lamps in series and generated adaptive circuit faults.
The levels
- Beacon blackout
Predict the dark open circuit, drag one cable into place, and observe the beacon light when the loop is complete.
- Storm line
Repair one of two gaps, predict whether the remaining gap matters, then close the entire route.
- Fault finder
Trace a circuit with a closed switch, diagnose the separate break, repair it, and verify the evidence.
- Twin beacon transfer
Predict, test, observe, and explain what happens when one lamp is removed from a two-lamp series loop.
Ready when they are.
