OBJECTIVE:

SHOW STUDENTS HOW THE LEMON-BATERRY WORK.

MATERIALS:

A CALCULATOR WITHOUT BATTERIES.TWO LEMONS.A KNIFE.THREE CLAMPS.FOUR SCREWSFOUR COINS.COPPER WIRE.

PROCEDURE TO FOLLOW...

FIRST...

SPLIT IN TWO EACH LEMON.

SECOND...

NOW WE WILL AN CUT IN EACH SIDE OF THE LEMONS IN THIS WAY...

THIRD...

INTRODUCE THE COINS IN ONE OF THE CUT. LEMON EACH MUST HAVE A COIN.

FOURTH...

THEN DO THE SAME WITH EACH SCREW.

FIFTH...

ORGANIZE THE LEMONS SUCH THAT WE STAY MORE OR LESS THE SAME DISTANCE.

CUT THE COPPER WIRE INTO THREE PIECES LONGER THAN THE DISTANCE BETWEEN LEMONS.

SIXTH...

SEVENTH...

NOW LET'S UNITE WITH COPPER WIRE, A SCREW WITH THE COIN OF THE LEMON NEXT AND TO MAKE SURE IT DOES NOT BREAK WITH PLIERS TIGHTEN. BUT I MAKE THE CLARIFICATION THAT THE EXPERIMENT TO WORK, THE FIRST LEMON COIN AND SCREW THE LAST, NO MUST BE UNITED NOTHING, SINCE THESE WILL MAKE A SIMILAR ROLE TO THAT OF A PLUG.

EIGHTH...

FINALLY WE CONCLUDE OF THAT OUR CIRCUIT WORKS. WE TAKE THE CABLES OF THE CALCULATOR AND THEM RUB WITH THE COIN AND SCREW LOOSE.

CONCLUSION...

BY INSERTING IN A LEMON WITH TWO OBJECTS MADE OF DIFFERENT METALS, FOR EXAMPLE A GALVANIZED SCREW AND A COPPER COIN. THESE TWO WORK AS ELECTRODES, CAUSING AN ELECTROCHEMICAL REACTION MEDIATED LEMON JUICE.

BYE...
