Kids Learn to Make Electricity

Science with Lemons

When kids hear the word science chances are they are thinking about boring class in school with lots of science homework. But before you shake your head and make a sour face, teaching your kids with science experiments they can easily learn how to make electricity work. Don't let them take science for granted, instead try this lemon experiment and show them how it works.

Turn on the Light Bulb

With Lemon Experiment

What if science could help you learn how to make your own electricity to turn on a light bulb. Sounds tricky but it really isnt. And with a few things you can gather, I am going to show you to make electricity with lemons! Science experiments have never been so much fun.

What You Need To

Turn A Lemon Into


  • a few lemons
  • a galvanometer (see below how to make your own)
  • 2 copper wires
  • a large paper clip
  • a pair of sharp scissors

Make A Galvanometer


Learn How to Make A Galvanometer

A galvanometer is an instrument designed to detect electric currents. You can make your own with a few simple materials.

  • a compass
  • 15 feet of bell wire (get this from the hardware store)
  • small shoe box

Place the compass in he center of your shoe box. Scrape off about 1/2" of insulation from each end of the bell wire. Starting from about 6" from one end, wind the wire tightly around the box, circling it about 2 dozen times. Lave another 6 inches of wire free on the other side of the box.

Rest your galvanometer on the table so that it is horizontal and turn it until the compass needle is parallel to the coil wire.

Attach the Galvanometer

How To Set It Up

  1. First you need to strip off any insulation on the ends of the wire.
  2. Then untwist the paper clip and attach it to an end of the one of the wires.
  3.  Squeeze the lemon gently with your hands. But don't rupture the lemon's skin. Rolling it on a table with a little pressure works great. Make two small cuts in the skin of the lemon and inch (2.5cm) apart.
  4. Insert the stripped wire and the paper clip into the skin of the lemon as well into the juicy part. Make sure that the 2 wires are close to one another but they should not be touching.
  5. Connect the free ends of the two wires to the terminal of the galvanometer. If you do not have a galvanometer you can make your own. If you make your own connect the free ends of the wires to your homemade galvanometer.

In some materials, particularly metals, the electrons farthest from the nucleus are not bound to a particular atom - they can move freely from one atom to another. Electricity is the flow of these free electrons in a wire:

What Happens

Did you see the meter move?

The Chemical reactions of the copper of the wire and the iron of the paper clip in the acid of the lemon juice draw electrons away from one wire towards the other. What is happening is that they flow out of the lemon through one wire, then go through the meter and then enter the lemon by the other wire.

Turn On the Lemon

Light Up A Light Bulb

Get a bulb of less than 1.5 volts. Then connect a few lemons and test to see how many lemon wet cells it will take to light the bulb up.

  1. Line up the lemons so that you can link them to one another.
  2. Make sure that you have copper wire and a paper clip in each.
  3. You should end up with two free wire ends, one attached to a clip.
  4. Connect these wire ends to the bulb.

The Tingle of Electrons

Taste Electricity!

If you touch the two wires that you have put into the lemon to your tongue at the same time, you will taste something metallic and you should feel a slight tingling sensation. And what you are tasting is and feeling is electricity!

The tingle felt in your tongue and the metallic taste is due to the movement of electrons through the saliva on your tongue.

Touching the electrodes to your tongue closes the circuit and allows an small electric current to flow. A single lemon produces about 7/10 of a volt of electricity. If you connected two lemons together, you can power an inexpensive digital watch (uses about 1.5 volts)

Science Experiments

Always Remember when doing any science experiment it is important to:

  • Follow all directions carefully and work in a clean, safe area.
  • Tell your parents/teachers you are conducting an experiment and ask if they want to help.
  • If you have questions or problems, feel free to ask an adult for help.
  • Don't do any experiment that you feel is too complex.

      CWanamaker - I would love to read all about your experiments with acid!

      I've done this with all kinds of fruits and vegetables. The key is acidity. I once made a circuit from jalapenos, lemons, potatoes, and cups of ketchup. Great Hub.

      drbj - you know as this 60Dc goes on I do believe I am getting quirkier and quirkier as it moves on. But I am having fun with things I havent done in years! Thanks for the thumbs up .. quirky is good in my books:)

      Taste the electricity? Don't think so. But I did enjoy reading about turning lemons into electric current. Here I thought they were only good for lemonade.

      Quirky but fun hub. Thanks.

      ~ samboiam - when my daughter was younger these projects were probably my favorite things to

      anglnwu - the many talents I have hidden.. ha ha .. I am like you a scaredy cat at heart but my daughter braved it . and i was just the bystander! I am going to need all the Jia Yu's you have in the next 3 days!

      ~ loriamoore - ah we are all kids at heart. . and this one is truly fun to see. . and I must say interesting all at the same time!

      ~ Om Paramapoonya - thanks for the visit and for the thumbs up . .it is always a good thing to read that someone likes it enough to point upwards!

      ~ sandy - back to school .. didnt we do that twice already...once when we were young and then again when our kids went .. ha! Then again we are never too old or too young to learn something new!!!

      I feel like I'm back at school. Thanks for the electricity lesson.

      Wow! This is quirky stuff. I had fun reading this (though I don't think I would be curious enough to try tasting electricity). Thumbs up!

      I don't have kids, but I might do this one myself, just for fun. Thanks for sharing.

      My Jia Yu girl, you're also the mad scientist? Thanks for the clear explaination. I don't know about putting wires on my tongue to taste the tingling sensation--I'm such a scaredly cat but for the bold, that's seem like an interesting proposition.Rated up and Jia Yu, the countdown is close.

      Great job. I got a real charge from this hub. Ooooooooooo.That was really bad. Seriously, it was very informative and fun.
