In my group of Ryan, Brijesh, and Riccardo, we finally arrived at “The Lemon Battery Experiment” to use for our project. We discussed using different fruits and seeing what voltages each one yielded. Trying out Apples, lemons and potatoes, we found that all fruits [and vegetables] gave about one volt of electricity. In our initial experiments we were even able to light up a small LED bulb with some luck.
For our experiment that we will bring to the High Schools, we were thinking about teaching the kids about circuitry and first, asking them to create a measurable voltage using wires and fruits. Then later we my challenge them to light the bulb if they had success with the first aspect of the experiment.
