Cleo Circuit World

Build your own circuits using an interactive wire diagram.  Then see the real-world components of your completed diagrams in action. Components include wires, switches, batteries, motors, light bulbs, buzzers, resistors, variable resistors, and ammeters. The bottom row of icons lets you switch between diagram view and component view.

This interactive is whiteboard friendly. But it could use some directions or online help. You can print your completed diagram. There is also a Save option, but it did not work for me. The interactive is flash-driven, so it requires a special browser for use on iPads.
