Students were given a set of electrical supplies and instructed to connect everything in such a way to light their light bulbs. There was an assortment of resistors, so some students had success lighting their bulbs, some did not. One resistor was much too weak and smoked to the class’s great excitement.
My favorite comment after the smoke was: “Mrs. Rolling, I’m afraid. Can we stop doing this now? I don’t need to light my light bulb.”
Supplies were bought from Home Science Tools.
