LEMON BATTERY Source: Adapted WWW.LEARNWITHCOMICS.ORG A battery produces from National electricity using Energy Education two different Development Project metals in a (public domain) chemical solution
BATTERIES PRODUCE ELECRICITY Shall we try Making a battery out of it? Let's try!
WWW.LEARNWITHCOMICS.ORG we need a copper ,a Zinc piece, small nail, Steel clips or wires as an electrical conductor ok,we have everything!

Roll the lemons by hand to release the juice inside.
insert copper wire/copper plate to one end and zinc plate or wire to the other end.
connect the copper to the long leg of the LED light.
connect theZinc to the shorter end of the LED light

SCIENCE BEHINDTHE BATTERY
Batteries are made of two different types of metal suspended in an acidic solution.
In this experiment, copper and zinc are the two metals and the lemon juice is the
z acidic solution.

a Because zinc loses electrons more readily than copper, zinc is the negative
t electrode (anode) and copper is the po sitive electrode(cathode). e
When the battery is connected with a L ED bulb, the circuit becomes closed.
Electrons flow from the zinc electrode through the LED bulb to the copper electrode and the bulb lights up. WWW.LEARNWITHCOMICS.ORG key words
