THE AIMTO MAKE AN EXPERIMENT AND FIND OUT IF FRUITS OR VEGETABLES PRODUCE ELECTRICAL ENERGY.

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

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

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

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

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.

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.
