How To Make a Lemon Battery

This how to make a lemon battery tutorial is perfect for a quick science fair project {or for a super fun home science experiment}.

I didn’t even realize you could make a battery out of a lemon!

Kids Activities Blog loves this project for making a fruit battery because it is a great way to teach science for kids.

LEMON BATTERY

When your kiddo comes home with news that it is science fair time at school a quick, easy, and educational option is the lemon battery. Recently, our two older kids, ages 7 and 9, presented ‘Lemon Power’ to their classmates and they were all awe struck.

Who wouldn’t be fascinated by using a lemon as a battery?

The process is simple and fun for the entire family.

MAKE A LEMON BATTERY

What You’ll Need:

  • 4 lemons
  • 4 galvanized nails
  • 4 pieces of copper
  • 5 aligator clip wires
  • A small light to power up

LEMON BATTERY EXPERIMENT

What To Do:

  1. Roll and squeeze the lemons to release the juice and pulp inside.
  1. Insert one galvanized nail and one piece of copper into each lemon.
  1. Connect the ends of one wire to a galvanized nail in one lemon and then to a piece of copper in another lemon. Do this with each of your four lemons until you have them all connected. When you are finished you should have one nail and one piece of copper unattached.
  1. Connect the unattached piece of copper (positive) and the unattached nail (negative) to the positive and negative connections of your light. The lemon will act as the battery.
  1. Turn on your light and voila you have powered up using lemon power.

FRUIT BATTERY

Once the light turns on and your littles realize that it is being powered by the lemon battery they created, have your camera ready because the smile on their face will be priceless.

This experiment offers great insight into the the complexity of a battery by breaking it down in simple terms. It also provides an awesome hands-on, visual representation of how it all works. By using a few items you already have in your home, constructing a lemon battery is an inexpensive way to see how electricity works!

The end result is not only a greater understanding but also a greater appreciation for the lemon whose uses far exceed being used to simply make lemonade.
