During this lab, my group tested three foods. We tested an orange, a potato and a lemon. We used a copper strip, galvanized nail for zinc, two wires to connect the metals with the voltmeter which we used to measure the volts of the three previously mentioned foods. Our first attempt was with the orange, which came to around 0.22 volts. The second was the potato which came to about 0.2 volts. The final one was the lemon and that one came out to an astonishing 0.7 volts. 0.7 volts is not a large amount by any means, but it was shocking when compared to our other results. I had overheard that an orange had gotten 0.4 volts with a different group and if that is true, I can come to the conclusion that each fruit, even of the same species, has a slightly different voltage. A couple of times, we would mix up which cord goes where while switching between fruits so the needle on the voltmeter would say that it had a negative voltage, but the voltmeter came out to the same number on both sides.

A second goal we were given closer to the end of the lab was to light a light bulb using the materials we had been using through the lab. I believe that only one group actually managed to accomplish this task by creating a long chain linking quite a few fruits.
