Insulators and Conductors

Year 3 have been learning about how to create circuits. They learnt that a circuit needs to be complete and must go to the positive and negative sides of the power supply. Year 3 also learnt about insulators and conductors, adding different objects in to break in a circuit and explore whether or not the light bulbs/buzzers worked. Year 3 found out that most of the metal objects conducted electricity and were surprised that the inside of a pencil conducted electricity. Year 3 discussed that wires are covered in plastic because it is an insulator, which means electricity cannot pass through it. This means that we can touch wires without getting an electric shock.
