@syedahijab7866: Working Model: Electric Circuit *Materials Needed* 1 cardboard or foam board (base) 1 × 1.5V AA battery (or 9V battery) 1 battery holder 1 small LED bulb (or 3V bulb) 1 small switch Insulated connecting wires (3–4 pieces) Hot glue or strong adhesive Colored paper for labels Scissors Marker Tape *Steps to Make It* 1. Cover the cardboard with colored paper to make a neat base. 2. Glue the battery holder on the left side. 3. Fix the switch in the middle. 4. Glue the LED bulb holder on the right side. 5. Connect one wire from the battery's positive (+) terminal to the switch. 6. Connect another wire from the switch to the LED bulb. 7. Connect the bulb back to the battery's negative (−) terminal to complete the circuit. 8. Insert the battery into the holder. 9. Turn the switch ON. The LED should light up, showing that the electric circuit is complete. 10. Add labels such as Battery, Switch, LED Bulb, and Connecting Wires for a professional exhibition look. *Working Principle:* When the switch is ON, the circuit is completed, allowing electric current to flow from the battery through the LED and back to the battery. The LED lights up, demonstrating a complete electric circuit.
