TEACH YOUR CHILD STEP BY STEP HOW TO GENERATE ELECTRICITY WITH LEMON

Many different materials can be used to create batteries; for instance, I demonstrated the operation of a lemon battery on report "What's Inside a Battery?" This project will teach you how to create your own lemon battery and use it to run a light.

The LED

To see the impact, you must connect the lemon battery to a device that requires very little power as a lemon battery can't produce much electricity. I'd want to introduce a part known as a light-emitting diode, or LED, as most light bulbs require more power than you'll be able to produce in this project.


When you supply this tiny electronic component with some power, it emits, or produces, light. LEDs come in a variety of hues, including red, green, yellow, and blue. Chapter 4 will provide more information about this component, and this book makes extensive use of LEDs. You will first only use an LED to monitor the power your lemon battery produces.




Supplies

Four lemons or one lemon cut into four pieces.


X 24 inches of copper wire (any copper wire will do, but

it’s important that the wire be copper).


X Four galvanized nails (most common nails for outdoor

projects are galvanized).


X Two alligator clips (Jameco #256525, Bitsbox #Cn262)

for connecting the LED.


X A standard LED (Jameco #333973, Bitsbox #oP002 for just this one, or Jameco #18041, 

Bitsbox #K033 for a variety pack). You’ll need several LEDs for the projects in this

book, so order at least 10 or a variety pack.


TOOLS NEEDED

A wire cutter (Jameco #35482, Bitsbox #TL008) to prepare the copper wire.


X A multimeter (Jameco #2206061, Bitsbox #TL057, rapid

Electronics #55-6662) to see whether your battery is working correctly

Prepare Your Wires

First, cut your copper wire into four 6-inch lengths. Strip about 1 inch of insulation from both ends of each wire. These will become the electrodes.

Insert Electrodes Into a Lemon

roll and squeeze a lemon so that you break up the small juice packets inside it, but not enough to break the skin. Then, use a nail to make one hole in one end, push a copper wire into that hole, and push the nail into the other end, as shown. This is the first lemon battery!

Create Four Lemon Batteries

A LED cannot be lit even with 1 V from a lemon. For additional electricity, let's make numerous lemon batteries!


Simply follow the steps outlined in Step 2 to transform the remaining lemons into batteries. (If you only have one lemon, you can divide it into four equal pieces.) You ought to currently possess four lemon batteries.

Connect the Lemons in Series

You must link your lemon batteries in series if you want to achieve a higher voltage. Simply connect the positive side of one lemon to the negative side of another to join two lemons in series. Keep in mind that the nail is negative and the copper wire is positive.
