Labs 3

Today my partners were Maddy and Emma S. we were in 'Motors' First we took a wire and wrapped it around a 3'' straw and then we attached it to a battery, and put a needle thorough it. it didn't work at first, because we only had one end touching the battery. so then we taped both wire ends to the same end of the battery. that didn't work either. when we put the wires on opposite sides it worked perfectly.
