Motors: A Magnetic Movement

Today Meena, Thalia and I did a lab on conducting electricity. We had to make something using a 6-Volt battery, 5 feet of insulated copper wire, a straw, and a needle. First, we wrapped the wire around the straw until there was 3 inches covered. Then we scraped off the insulation on the ends of the wire. Next we touched the end of the wire to both sides of the battery. Then we inserted the pin into the wire covered straw. The first time that we did it, Thalia was holding the battery and wire and it sparked in her hand. It was so funny! She dropped the battery and ran... to the bathroom I think. Haha! Anyways, now its Meenas turn. She had been holding the battery for about 6 minutes when all of a sudden she screamed. Apparently, the wire gets really hot when you touch it. Thats all that we had time for today. Catch ya next time!
