I am doing a science project and i need help?

Question

I am making a battery lemon and i am doing what i am sopposed to do but it wont work i really need help. plaese

Answer 1

I LOVED THIS PROJECT! you may be having problems with the penny. are you sure it is copper? if not you can always go to home depot or radio shack and get zinc and copper strips. If you dont have the proper nails, a dime will work just as fine (zinc)



The lemon: A large, fresh, "juicy" lemon works best.
The nail: Galvanized nails are coated in zinc. I used a 2" galvanized common nail.
The penny: Any copper coin will work. (Canadian pennies from 1960 - 2001 all worked)

Creating the battery: Insert a penny into a cut on one side of the lemon. Push a galvanized nail into the other side of the lemon.
The nail and penny must not touch.


This is a single cell of a battery. The zinc nail and the copper penny are called electrodes. The lemon juice is called electrolyte.
All batteries have a "+" and "-" terminal. Electric current is a flow of atomic particles called electrons. Certain materials , called conductors, allow electrons to flow through them. Most metals (copper, iron) are good conductors of electricity. Electrons will flow from the "-" electrode of a battery, through a conductor, towards the "+" electrode of a battery. Volts (voltage) is a measure of the force moving the electrons. (High voltage is dangerous!)

Here is a google video on how to make one:

Answer 2

you need to be more specific.. what are you doing and how will you know if the experiment IS working? (what's the lemon supposed to do?)
