In the pre-activity we created a electric circuit by connecting the two ends of a wire to a battery. After that we waved the circuit around a compass to see what happened. The needle of the compass followed the circuit. I think this occurred because the battery could have magnetic material inside. After it passed through the wire it returned to the battery which caused it to magnetize.
In the main activity we used a battery two types of wire, 5 paper clips and a nail. First we wrapped the normal wire around the nail 31 and then we connected both ends to the battery. Nothing happened at first. Then we used the copper wire and we wrapped it around the nail 20 times but nothing happened. On our last try we scrapped of some of the layer of plastic off the copper wire and then we tried again. We wrapped it around the nail 33 times and when we tried to grab some paper clips, it worked! This might have happened because the circuit could have magnetized the nail.
