The children had two Science lessons about electricity with Ms Olivari Saliba and Mr Andrew Vella. The lessons were about conductors and insulators of electricity. Certain materials allow electricity to travel through them (all metals) and these are called electrical conductors. Other materials do not allow electricity to travel through them (fabric, paper, plastic, wood, glass, stone to name a few) and these are insulators. The children learnt that some materials conduct electricity while others do not.
