About this worksheet
A Year 6 science knowledge check on circuits, matched to the England National Curriculum. Its twelve questions sit in four sections. Pupils name the symbols for a cell, buzzer, open switch and lamp, then decide whether a buzzer sounds when the switch is open. They compare a bulb with one cell against a bulb with two, and predict what happens when bulbs, cells or longer wires are added. The last section has Maya's quiet buzzer and Leo's circuit, where two cells face positive to positive. A final question asks why more bulbs make every bulb dimmer. The answer key gives model answers.
