Room One made an electrical circuit to demonstrate the flow of electricity. Each group used wire, batteries and a light bulb. We used a paper clip as a switch. When we connected the paperclip the electrical current flowed through and the lightbulb turned on. When we opened the paper clip the electrical current did not flow and the lightbulb did not turn on. This practical activity helped us to see how electricity flows and what substances conduct electricity. View the photostory to see our demonstration and the fun that we had.
