When it was time to present, Maya spoke clearly. She described how circuits needed a closed path, how switches control flow, and why safety mattered—insulators stop accidental shocks. She held up the paperclip as a conductor and the rubber strip as an insulator, and the class saw the bulb’s reactions exactly as in their experiment.
