In Science today, we built on our learning last week to set up and carry out an investigation into which materials are electrical conductors and which ones are electrical insulators. We made predictions about what which ones we thought would conduct electricity before testing our predictions. We found that copper, steel and brass all conducted electricity which made us conclude that metal is an electrical conductor. We also used our general knowledge of electrical safety to infer that water must also conduct electricity as it is dangerous to use water near electricity because you can get an electric shock. Great work, Year 4!
