Physical Science Thank you for your input. When two dissimilar metals are placed in a common conducting solution,electricity will be produced. This is the basis of the electro-chemical cell, or wet cell.
A few drops of dishwashing soap Paper towels Aluminum foil at least nine by 60 centimeters Scissors At least one lemon preferably with a thin skin Plate Knife and an adult's help when using it At least two plastic-coated paper clips Preparation Wash your pennies in soapy water, then rinse and dry them off with a paper towel.
This will remove any dirt sticking to them. Carefully cut three aluminum foil rectangles, each three centimeters by 20 centimeters. Fold each strip in thirds lengthwise to get three sturdy one-centimeter-bycentimeter aluminum strips.

Voltaic batteries of all shapes and sizes . Does one particular fruit or vegetable outperform the others? With what you learned about how batteries generate electricity, why do you think that one type of produce made a stronger battery?
In this activity you will make a very low-voltage battery. The amount of electricity generated by this homemade battery is safe, and you will even be able to test it by touching your finger to it and feeling the weak current.
Higher voltages of electricity, however, can be very dangerous and even deadly; you should not experiment with commercial batteries or wall outlets. Procedure Place the lemon on its side on a plate and have an adult carefully use the knife to make a small cut near the middle of the lemon away from either end.
Make the cut about two centimeters long and one centimeter deep. Make a second, similar cut about one centimeter away and parallel to the first cut.
Push a penny in the first cut until only half of it is showing above the lemon skin.
Part of the penny should be in contact with the lemon juice because that is what serves as the electrolyte. This copper penny in contact with the lemon juice serves as your first electrode. If your lemon has a very thick skin, you might need an adult to carefully cut away some lemon peel.
Why do you think is it important for part of the penny to be in contact with the lemon juice? Slide one of the aluminum strips in the second cut until you are sure part of the aluminum is in contact with the lemon juice. Can you guess which part of a battery the aluminum strip that sits inside the lemon is?
Do you think it is important for the aluminum to be in contact with the lemon juice? You have just made a battery! It has two electrodes made of different metals and an electrolyte separating them.
Do you think this battery is generating electricity or is there still something missing? Your battery can generate electricity but will only do so when the electrodes are connected with something that conducts electricity.
To make a connection attach the second aluminum strip to the part of the penny sticking out of the lemon with a plastic-coated paper clip. Make sure the aluminum touches the penny so electricity can pass between the copper and aluminum.
You used an aluminum strip to create a connection; would you expect a plastic strip to work as well? Do you know why you do not need to create a connection to the second electrode for this particular battery?Fruit-Power Battery – SICK Science!
Pennies, lemons, and nails combine to convert chemical energy into electrical energy. Voltaic batteries of all shapes and sizes . Study About Fruit Battery ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world.
It is made by inserting two different metallic objects, for example a galvanized nail and a copper coin, into an ion bridge (for example a lemon, a potato or paper soaked in salt water or acid).
A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires.
ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world. Many questions about potato-powered battery are explained in this study.
Thus, this study is a complete overview about potato-powered battery. Literature a) Foreign Two metals – an anode, which is the negative electrode, such as.
