Material from website: Electric Circuit Design Challenge by Philip Kukulski, Metro Detroit

Individually or teams of 2 students. If you submit an answer that fails, you are out of the running for the extra credit. Your score depends on the highest level you complete. You only need the circuit to perform the task of last level; previous circuits can be dismantled.

Levels: 1) Make a light bulb light brightly using 4 batteries.2) Add an on/off switch.3) Make 3 light bulbs light brightly with all 3 with the same brightness (same current, measures the same number of amps).4) Have a switch that turns on/off 2 of the 3.5) Have a switch that turns on/off all 3 lights.6) Make a circuit with one main on/off switch that will turn on/off 3 bulbs, each with a different brightness.Use the non-contact Ammeter to check for different currents.7) Change the circuit so 1 switch will turn on/off all the lightsand a second switch will change the lightsfrom all being the same brightnessto all being different brightnesses.Up to 3 points extra credit for the team that does best, first.
