Year 4 Science: Creating and Testing Switches

This week in Year 4 Science, pupils have been developing their practical skills by exploring how to create and use switches in simple electrical circuits. Using a range of everyday materials such as card, aluminium foil, paper fasteners, and paper clips, the children designed and built their own switches to control a circuit and light a bulb.

Pupils were encouraged to experiment with different types of switches, including those that push, slide, and turn. They then tested each design within a simple series circuit to see whether it successfully completed the circuit and allowed electricity to flow.

As they worked, pupils thought carefully about which designs were most effective and discussed why some switches worked better than others. This helped them develop their understanding of how circuits function and the importance of choosing the right materials.

The lesson promoted creativity, problem-solving, and collaboration, with pupils showing great curiosity and perseverance. It was fantastic to see them thinking like scientists—designing, testing, and improving their ideas to create working electrical switches!
