A classic science activity for kids is the Fruit Battery. Fruit electricity is a fascinating science experiment for kids! Learning about Electricity can happen early on in life and can happen with the lemon battery!
You can create electricity from a piece of a fruit…
…and well, a few other items.
If you have never done this activity with children, you should definitely check it out. There is something about a lemon lighting up a digital clock that truly ignites a child’s desire to learn. Often to get a child hooked onto a topic, we have to “wow” them.
Fruit Electricity Science Activity
The moment I observe my son’s eye widen and his mouth fall open, I know I have succeeded in hooking him into wanting to learn more. Be sure to download this FREE fruit & vegetable activity sheet to go along with your experimenting!
Fruit Battery – An Easy Science of Electricity Activity for Kids
The Lemon Battery experiment is a wonderful example. While you can put these activities together with various items around your home, there is a kit that you can purchase online at an extremely reasonable price.
Materials Needed – Fruit Electricity Activity
- lemon (big & juicy works best)
- lemon clock kit OR
- galvanized nails (zinc)
- pennies (copper)
- alligator clips
Approach – Lemon Clock
- Use the knife to cut the lemon in half
- Insert the copper and zinc wires as indicated on the instructions of the lemon clock kit
- Take your penny & insert it halfway into each side of the lemon
- Then take the nail & insert it into each side the lemon (make sure not to touch the penny)
- Connect the pennies and the nails with alligator clips
Further Electricity Learning
Explore with different types of objects such as styrofoam, play dough, potato, fruit, eraser, a block of wood, and cucumber.
Fruit Electricity Facts
Batteries contain two metals suspended in an acidic solution. In the case of the lemon battery, the metals are zinc and copper. The acidic solution comes from the lemon's citric acid. The metals are electrodes where the current enters and exits the battery. In the lemon battery case, the current flows from the copper to the zinc and within the acidic solution inside the lemon. The lemon battery is connected to the clock and you have completed the circuit.
