F2 Science Electricity Exercise Top Apr 2026

For the application, each group had to invent an everyday device that uses conductors and insulators. Luka suggested a bicycle light: metal wires connect the battery to the lamp, while the handlebar grips use rubber to protect the rider’s hands. Siti sketched a school locker alarm that lights up if the metal door closes improperly—metal contacts and insulated wiring keeping students safe.

“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. f2 science electricity exercise top

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. For the application, each group had to invent
