The purpose of the experiment is to understand how battery works and find out which fruit and vegetables that we eat can be used as an alternative way for a battery source. I become interested on seeing how batteries where used to power up my flash light and toys. The information from this experiment will help kids like me to power something for a short period of time and take our thoughts forward in the world of science. Hypothesis :
My hypothesis is that lemon and orange which contains more juice compared to other citrus fruits will generate more voltage that would be enough to light a simple low voltage light bulb for a very short time.
Materials : Items needed Quantity Lemon 1 Orange 1 Onion 1 Tomato 1 Potato 1 Paper 1 Pencil 1 Clock 1 Copper metal 2 Zinc metal 2 Cables Multimeter 1 Light Blub 1 Procedure: 1. Gather all things needed for experiment. 2. With the help of the adult, remove plastic coatings at the end of all wires with scissors. 3. Gently roll each fruit on a table to soften it or squeeze it with your hands.
The purpose of this is to make the juice flow inside the fruit without breaking the skin. 4. Take the white cable and tie one end to the Zinc metal contact and the other end of the Copper metal contact. 5. Take the red cable and tie one end to the Copper metal contact. 6. Take the black cable and tie one end to the Zinc metal contact. 7. Insert the metal contacts to the fruit. 8. Watch fruit generate energy to power the clock. 9. Measure the voltage by connecting a Multimeter and record the values. Check the values 3 times 10. for each fruit and record the average value. 11.
Remove the Multimeter and connect a light bulb to the conductors. 12. Note the result. Results: Fruits do not make very good batteries because they generate very low power. They are not an appropriate alternative to AA Batteries. Conclusion: My results disproved my hypothesis which was that the fruits would generate enough voltage to produce light. However, the results proved that fruits and vegetables do produce voltage and Potato produced the most. ABSTRACT The purpose of this project was to understand how battery works and find out which fruit or vegetable would generate enough electricity to light a light bulb.
A battery is just a container of chemicals that react together to produce a flow of electrons, which is what an electrical current really is. Here the checmical energy gets converted into electrical energy. A battery has two terminals, one positive and one negative. In my experiment, I used copper rod (positive end) and zinc rod( negative end) and fruits and vegetables which I had at home and Multimeter to measure the generated electrical energy. The fruits was cut into half and the copper and zinc metal was inserted into the fruits. The copper metal acts like the positive end and the zinc metal acts like the negative end.
The juice in the fruits acts as medium so that the negative particles moves toward the positive end. The flow creates a chemical reaction which creates voltage. A small digital clock was connected to metals. The voltage generated by different fruits was measured using a Multimeter. A light bulb was then connected to metal ends. My results disproved my hypothesis which was that there would be enough voltage to produce light. However, the results proved that fruits do produce voltage but not that sufficient enough to power a light bulb.
