Powering Up Science: Investigating Conductors and Insulators in Year 4

Year 4 have been busy becoming young scientists as part of their Electricity topic, taking part in an exciting practical investigation in the school science lab. The focus of the lesson was to discover which materials are electrical conductors and which are insulators, giving pupils a hands-on opportunity to explore how electricity travels.

Pupils carefully planned their investigation before beginning, discussing how to make it a fair test by deciding what they would keep the same, what they would change and what they would observe. They created a list of the equipment they would need, including cells, wires and bulbs, and drew clear series circuit diagrams using the correct electrical symbols they have been learning in class.

Once their circuits were ready, pupils tested a range of different materials by adding them into the circuit one at a time. If the bulb lit up, the material was identified as a conductor; if it stayed off, the material was classed as an insulator. Before testing, pupils made sensible predictions and carefully recorded their results in a table.

A wide variety of materials were investigated, including metal coins, paper clips, aluminium foil, lolly sticks, rubber, Lego, plastic rulers and paper. Using their results, pupils discussed patterns, compared findings and drew thoughtful conclusions about which materials allow electricity to pass through them and which prevent it.

It was fantastic to see such focus, curiosity and scientific thinking throughout the investigation. Well done Year 4, for your excellent teamwork and growing confidence as scientists!
