About this worksheet
A Year 6 science cloze on voltage and bulb brightness, over two pages with an answer key. Pupils fill twelve gaps in a three-paragraph passage from a bank of twelve words such as volts, current and components. The passage moves from what a circuit needs to how more cells make a lamp brighter and a buzzer louder, and why more lamps make each one dimmer. Two diagrams show a 1.5 V circuit and a 3.0 V circuit. Pupils explain the brighter lamp using the word voltage and predict a buzzer's volume with one cell. It covers two England National Curriculum electricity objectives.
