Year 4 have been learning about electricity in their science lessons this half term. They have explored how to create working circuits, and this week the children investigated which materials conduct electricity or insulate against electricity. They planned their investigations, considering what they would keep the same and what they would change every time to make their test fair, before trialling the different materials in their circuits to see whether the electricity flowed through a conducting material to light up the bulb or whether it was blocked by an insulating material.
