Along with the 6th graders in Udavi we had created a working model of a generator using a motor. The motor was connected to a pulley and routed to the cycle wheel. In turn when the wheel was rotated it produced electricity to power up the India map the students created with LED’s they also figured out that the LED’s did not glow in both direction of rotation of the wheel they found that there was tow terminals to the LED (Anode and Cathode) and it was different from normal bulbs. All the LED’s where connected in parallel to each other. with the generating power source in series.
