A Knowledge Organiser that captures the essential knowledge and skills learnt throughout the unit Design and technology, Year 4, Electrical systems – Torches.

This resource supports pupils in exploring how electrical circuits are used in everyday products, with a focus on designing and testing a battery-powered torch. Key vocabulary is clearly defined, including terms like battery, bulb, conductor, insulator, series circuit, and switch. It highlights the practical application of these components and introduces pupils to testing and evaluating their designs. Visual aids reinforce understanding by linking components to familiar products such as remote controls and mobile phones. The organiser provides an accessible foundation for understanding electrical systems in a real-world context.
