Exercise Top — F2 Science Electricity

“Groups of three,” Mr. Adebayo called. “You’ll build a simple circuit, test conductors and insulators, and explain one real-life application.” Maya teamed with Luka and Siti. They spread their kit on the lab table: a small bulb, battery, wires, a switch, a metal paperclip, a wooden skewer, and a strip of rubber.

On the walk home, Maya felt proud. The exercise had been more than experiments and notes; it turned invisible currents into ideas she could picture in everyday things—lights, alarms, the tiny spark of understanding that makes science feel alive. f2 science electricity exercise top

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. “Groups of three,” Mr
