About this worksheet
Five pages on series circuits for Year 4, with an answer key. Pupils label pictures of a cell, a lamp, a switch and a buzzer. They then decide whether the lamp lights in four circuits. One is a complete loop, one has a loose wire, one has an open switch and one has both wires on the positive terminal. Gap sentences use complete, energy and break, and a true or false table checks the rules. In Circuit Detective, pupils give two reasons why Leo's lamp stays dark. It follows the England National Curriculum.
