F2 Science Electricity Exercise Top (2026)

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.

Mr. Adebayo praised their demonstration. “Good observation and a neat application,” he said. He asked a final question: “How can we make circuits safer at home?” The group answered in unison: use insulated wires, switches, and careful design—plus never handle devices with wet hands. f2 science electricity exercise top

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. On the walk home, Maya felt proud

“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. Adebayo praised their demonstration
