The result was that a potato is the world’s tastiest battery. I will be testing a red, yukon, white rose, and a plain potato. I will also test a clock and a flashlight. If red, yukon, white rose, and plain potatoes are tested on a clock then the plain potato will produce the most electricity because it is the biggest.

Background Research. ... Potatoes do not store energy like an actual battery; they simply give electricity the ability to flow through its starch salt and water in order to power the clock. ... Thanks to my research I strongly feel that the sweet potato will conduct the most electricity out of all three potatoes.

It is good to have some background information on the traveling of current from the positive to the negative terminal of a battery and that of electrons in the opposite direction before embarking on the investigation. Then, in case the potato battery clock does not work, they know how to troubleshoot.

en.wikipedia.org/wiki/Lemon_battery

A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires. Power generated by reaction of the metals is used to power a small device such as a light emitting diode (LED).. The lemon battery is similar to the first electrical ...

To create a potato battery, start by inserting a galvanized nail near the middle of the potato and pushing it in until it's almost to the other side. Next, insert a copper coin halfway into the potato about 1 in (2.5 cm) away from the nail. Make sure the nail and coin aren't touching each other! Then, using the end clips of a voltmeter, attach one clip to the nail and the other to the penn...
