In this fun <br /> experiment, you can build a simple circuit and discover which materials are <br /> conductors and which materials are insulators. Conductors allow electrons to <br /> flow through them, but insulators resist electron flow. <br /> Materials you will need: <br /> - Short string of Christmas lights, or <br /> segment of Christmas lights cut from a <br /> longer strand (ask an adult to cut the <br /> Christmas lights with wire cutters or a <br /> sharp knife) <br /> - One 9 volt battery <br /> - Two wires with alligator clip on either <br /> end. , <br /> - Wirestrippers <br /> - Materials to test in your circuit <br /> • Penny <br /> • Nickelf;* <br /> • Dollar bill TN I <br /> • Button J: <br /> � f r <br /> • Popsicle stick , <br /> • Pipe cleaner <br /> • Paper clip <br /> • Small nail <br /> • Metal key <br /> • Piece of yarn or string u <br /> • Twig <br /> • Pencil <br /> • Piece of aluminum foil <br /> • And any other small thingsJ <br /> around your house or <br /> classroom that you want to <br /> test! <br /> 9 <br />
