attaching it to a battery via jumper cables. The independent variable is the battery charge (1.5 V) and the dependent variable is how fast the motor spins. The lab doesn’t have multiple experiments for us to test this but I would hypothesize that the two variables would have a positive correlation: higher voltage‚ faster spin. I built my tiny motor out of magnet wire‚ a magnet‚ two paper clips‚ a 1.5 V battery‚ and two push pins. I curled the magnet wire around the battery so that it was in a
