    My 9 yr old daughter needs to do a simple electronics project. Must run on D cells. Have parallel and series circuits. Needs some switches, and "energy converters" ( light bulbs, motors, fan elecromagnet etc.) She is looking to me for help and I am drawing a HUGE blank trying to come up with something for her. Anybody have any design ideas or have done a simple science project like this. ANY input is appreciated.

    You could have one parallel branch with a switch and bulb. The other with just a switch. You could vary the brightness by opening and closing the switches.
