Students used lemons and potatoes in making their own batteries

For their study of electricity, students in (9-12) learned how batteries work and created their own natural batteries using lemons and potatoes. Students connected everything together with leads, alligator clips, a zinc nail and a copper penny or copper nail.  This allowed the acidic juices (electrolytes) to allow the electrons to flow through the wires until it reached a small light at the other end. Teacher Nancy Buchman loved watching her students’ faces light up when the bulb lit up.
