DOES FOOD PRODUCE ELECTRICITY?

HYPOTHESIS


We believe that fruits and vegetables produce electricity because they have positive and negatives charges that cause the circuit is closed. By a few experiments we will try to find out the answer of our principal question: Does food produce electricity?

BACKGROUND RESEARCH

Electricity requires the presence of negatively and positively charged particles: electrons (-) and protons (+). In order for electricity to flow, there must be movement of electrons along a path.

We have found that vegetables and fruits are the best conductors and producers of electricity. But, can other kind of foods produce electricity? Do fruits and vegetables have better characteristics than other foods?


EXPERIMENT

MATERIALS

Magnesium strip

Copper strip

Yellow connector cable

Tape

Clock with black wire and red wire

Foods:

  • potatoes

  • lemons

  • tomatoes

  • carrots

  • pears

  • beans

  • bananas

  • ham

  • milk

PROCEDURE

  1. Connect a magnesium strip and a copper strip with the yellow connector cable. Cover the strip/wire connection using the tape

  2. Connect the black wire on the clock with a magnesium strip , and the red wire on the clock with a copper strip and cover them with a tape.

  3. Place the copper and magnesium strips in the food as shown in the drawing. Strips should not touch each other.

CONCLUSIONS

After these experiment, and trying different kinds of food, we get the conclusion that if the food that we use has the presence of electrons and protons, it always can produce electricity and make objects that need electricity, work. Also we realised that fruits and vegetables are better to produce electricity but aren’t the only ones that can do it although the most part of food that produce it are them.
