__**materials:**__

 * ==**large lemons**==
 * ==**copper coin**==
 * ==**galvanized nail**==
 * ==**knife**==
 * ==**volt meter**==
 * ==**copper wire**==
 * ==**Get one or a few large lemons.**==

__**Procedure**__

 * 1) ==**Stick the nail at the top of the lemon. Use a knife to create an opening, if the nail is not sharp enough to puncture the lemon.Slice a slit, which can fit the copper coin halfway.**==
 * 2) ==**Fit the copper coin into the slit, to create your lemon battery.**==
 * 3) ==**Once done, use a volt meter to confirm if the battery is producing electric currents. If it does, the next step is to power an electrical item.**==
 * 4) ==**Hook up the battery to a small light bulb or a simple electronic device like a calculator.**==
 * 5) ==**If the battery fails to come up with enough power, create several lemon batteries. Connect them using copper wire, which is hooked up to the coins and nails of all the batteries.**==
 * 6) ==**Hook up the copper wire to the device, powering it upon connection**==

**Building more lemon batteries and connecting them with a metal wire from "+" to "-" adds the voltage from each cell.**
==4 lemon batterys combine to produce a voltage of 1.788 volts. This combination still does not create enough current to light a small bulb. Note the red wire connecting the batteries is joined from "+" (penny) to "-" + (nail).==

__Conclusion:__
=__Journal entries__= March 16th: today i searched for science fair project i found some interesting ones but they were very complicated so i just stuck with a very simple one, im trying to find if the size of the lemon effects its electrical output so I think this will be a very entertaining project!!

march 30: today i tried to do the project i thought it would be easy, but it definetly was not i tried to do the procedure but it wasn't as simple but i finally got it so i cant wait untill the science fair that would be great if I lit a lightbulb at the science fair............

April 12: today i tried to see if the size mattered i bought a samll one and a big one.. the big one lit brightly but the small one really didnt light it was very dim so i guess the size really does matter.........

April16: today i tried it with different supplies just for fun and it still worked! i tried the nail just a rusty nail and i tried it with a quarter but it didnt work as well as it did with the real supplies......

may 11:soo teh project ios due tomorrow and im already....the time went by soo fast, well i hope i do great :)
