F2 Science Electricity Exercise Top [ 2024-2026 ]

“Why?” Siti asked, writing notes. Maya explained, remembering last week’s lesson: “Metals have free electrons that move easily, so they conduct electricity. Wood and rubber don’t—so they’re insulators.” She flicked the switch and the bulb went out, then on again. The simple actions felt like magic harnessed by rules.

They began by connecting the battery, bulb, and wires. The bulb glowed a soft orange. “Success!” Luka whispered. Mr. Adebayo smiled and nodded. Next came testing. They touched the paperclip into the circuit and the bulb shone brighter. When they tried the wooden skewer, the bulb stayed dim. The rubber strip did nothing at all. f2 science electricity exercise top

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. “Why

“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. The simple actions felt like magic harnessed by rules
