Electrical Circuits

In science we've begun to explore electrical circuits, and what they must have in order to be complete. The kids were handed a battery, wire, and another wire with a light bulb attached, then they were told to make the bulb turn on. That's the most direction they were given.

All groups were eventually successful in turning on the light. It's always fun to hear their conversations as they make their cases for why their way will be successful. Most groups figured out they didn't even need the extra wire!
 After they finished, we discussed what parts an electrical circuit needs to be complete. It must have a power source, conductor, something that needs the power, then finally the circuit must be closed. We also discussed the idea that while circuits don't have to have an insulator on the wires, it's probably a great idea. ;)
