In Year 4 this week, we were working scientifically by designing practical enquiries in order to test our predictions. We decided on a question to investigate, decided how we would investigate and made predictions. Once we were ready we built a series circuit with a bulb and, in place of a switch, we connected a range of different materials to see if the bulb would still light. We found out that most of the metal objects conducted electricity so the bulb lit. We also discovered that the majority of the items in our pencil cases were insulators so the bulb didn’t light whilst these items were connected.
