Everything in the circuit should make a circle. (Did you know, the word <br /> circuit comes from the word circle!) Clamp one end of the string of lights to the <br /> positive (+) terminal of the battery, and clamp the other end of the string of <br /> lights to the negative (-) terminal of the battery. Ask an adult to strip some of <br /> the insulation off the ends of the Christmas lights if no wire is exposed. Make <br /> sure the alligator clamps touching the Christmas lights are clamped to the copper <br /> wire inside the plastic insulation. <br /> t,f <br /> M" <br /> f <br /> r t <br /> 2) If your circuit is hooked up properly, and if your battery and lights are <br /> working, your Christmas lights will light up! But as soon as you break the circuit <br /> somewhere, electrons stop flowing and the lights go out. In how many places can <br /> you break the circuit? <br />
