Students will understand that electricity flows through a circuit which must be closed for the energy to travel, that different materials can allow energy to flow or prevent it from travelling and that the energy source must be properly connected for energy to flow. At the end of this unit students will be able to independently identify complete and incomplete circuits, offer ways to fix incomplete circuits, identify parts of a circuit, and create a circuit that is a part of a lighthouse.
