2. THE AIM
TO MAKE AN EXPERIMENT
AND FIND OUT IF FRUITS
OR VEGETABLES PRODUCE
ELECTRICAL ENERGY.

3. To find, collect and analyze theoretical
information about energy;
To make an experiment;
To summarize the data gained during
the experiment;
To present the research work.
THE TASKS
METHODS: WORK WITH LITERARY RESOURCES,
OBSERVATION, EXPERIMENT, RESEARCH, ANALYSES,
COMPARISON

4. Potato, lemon and apple juice contains
many water soluble chemicals that may
cause a chemical reaction with Copper
and Ferrum electrodes. That is why it is
possible to get electricity from these
edible items.
HYPOTHESIS

5. Matter is made up of atoms. In these atoms,
there are electrons that are constantly moving.
The movement of these electrons depend on
how much energy is has. This means every
object has potential energy.
THEORETICAL PART

6. Humans can force these moving electrons along a
path from one place to the other. There are
conductors, that carry this energy. Some
materials cannot carry energy in this form, and they
are called insulators. We generate electrical energy if
these electrons move from one atom to the other,
with the use of magnetic forces.
Electrical energy

7. THEORETICAL PART
• Batteries generate electricity through a
chemical reaction between two different
electrodes and one electrolyte.
• In the experiment are used Copper and
Ferrum electrodes and fruit or vegetable
juice as electrolyte.

10. CONCLUSION
• It is possible to get electrical energy and
make a battery from a lemon, an apple and
a potato.
• We get low amperage (50 μA=0,00005 A )
• Chemical reaction between electrodes and
an electrolyte ends and, like any batteries,
fruit / vegetable battery expires - it gets
empty really fast.
