This activity (on page 3 of the PDF) is a full inquiry investigation into conductivity. Learners will harness the surprising electricity of fruit when they create a battery out of a lemon stuck with copper and zinc nails. Wiring the nails to a volt meter starts the experimenting stage, trying different wiring connections, different fruit and even making a series of fruit and veggie batteries to make more power. Relates to linked video, DragonflyTV GPS: Body Electricity.
