About this worksheet
An electrician needs a mixed tray of materials sorted. This three-page Year 4 science sheet opens with a Key Fact box: conductors let current pass through easily, most good conductors are metals, and insulators do not let electricity through. Pupils then sort sixteen items into Electrical Conductors and Electrical Insulators. The items split eight and eight. Graphite pencil lead is the one non-metal conductor, and the answer key explains why it is tricky. In Think Like a Scientist, pupils name the hardest item and add a new conductor and insulator with their materials. It follows the England National Curriculum.
