...soon as I noticed that Alessandro Volta was an option I thought it would be a fun assignment to learn about him. Volta was a physicist, chemist, and a pioneer of electrical science. He contributed to today by inventing the electric battery, discovering methane and internal discussion. He not only did those things he was also able to apply part of his last name as part of potential energy term for the battery “Volts.” Volta was born in Como, Lombardy, Italy on February 18, 1745. His parents’ names were Donna Maddalena, who came from a family of Counts and Filippo Volta, who came from a noble lineage. His parents had seven children who survived childhood....

...Final Investigatory Project for Group 5 I. Problems and Setting A. Introduction Batteries, years ago, have taken the world by a storm and have since than became a necessity in one’s household. Sadly, even though they are tremendously useful, batteries have drawbacks, such as semi- affordable costs, limited shelf life and pollution. Our group had an idea on how to make an alternative to this that would not only work like the real thing but would also be healthy to our environment and light in our pockets. This idea turned out to be realty and became the main goal of our Investigatory Project. B. Problems Finding an item that is easy to obtain and at the same time affordable, simple and earth- friendly is not an easy task. After a lot of thought, our group decided to use one of the objects that is almost always present in our daily lives: fruits and vegetables. Will these everyday materials such as apples, bananas, oranges, lemons and potatoes conduct electricity? Well, let’s see about that. C. Hypothesis A circuit is made up of a path, a source and a load. We believe that we should connect them with a (+) and a (-) wire so that the flow will be even with no reverse polarity. The load we thought of using was a battery- operated clock, one of the most common materials found in almost everyone’s household. We believe that it would work because the organic materials we will use have electrolytes that flow freely on its own. Thus, it will flow into conductors to make...

These two molecules are the second and third largest ingredients in electricity • By adding electricity’s most abundant ingredient-copper-and its fourth and final ingredient-zinc-a fresh batch of electricity can be made and extracted • A potato battery is an electrochemical battery, otherwise known as an electrochemical cell. • An electrochemical cell is a cell in which chemical energy is converted to electric energy by spontaneous electron transfer • The zinc in the nail reacts with the copper wire • The potato acts as a sort of buffer between the zinc ions and the copper ions • The zinc and copper ions would still react if they touched within the potato but they would only generate heat • Since the potatoes keep them apart, the electron transfer has to take place over the copper wires of the circuit...

...The Fruit Battery March 19, 2007 7th grade Abstract My objective was to determine which fruit would make the battery for a clock. Procedure 1. 2. 3. 4. 5. Gather all things needed for experiment. Wash hands for safety. Take the clock module and place fruit in the two holders. Remove plastic coatings at the end of all wires with scissors. Take the black cable and tie one end to the Zinc metal contact. 6. Take the blue cable and tie one end to the Zinc metal contact and the other end of the Copper metal contact. 7. 8. 9. Take the red cable and tie one end to the Copper metal contact. Insert the metal contacts to the fruit. Attach the black and red cable to the spring contacts. 10. Watch fruit generate energy to power the clock. 11. Adjust the time on the clock. 12. Set the date. 13. Set the month. 14. Set the day of the week. 15. Set the stopwatch. Results According to my experiments, the tomato was the best battery for a clock. The tomato has been used for a week and is still going. The tomato has the most acid. The lemon did not work at all. The apple lasted 1 day. The orange lasted 3 days. Conclusion My hypothesis was that the lemon and the orange will produce electricity for the longest period of time. The tests went well. The only problem that was encountered was the lemons not working.

...Potato Powered Clock Theory: Potato as a Battery Hypothesis: Potatoes have starch in them which is a natural sugar that can be broken down naturally for a release of energy and generate enough power to run a digital clock. Problem Statement: Can ordinary potatoes power a digital clock for more than 24 hours? Variables: * Independent Variable – Potato * Dependent Variables – Clock, connection wires, copper and zinc plates Materials Needed: * Digital Clock with 2 Wires * 6.25” Connecting Wire * Transparent Tape * 2 4” Copper Strips * 2 4” Zinc Strips * 2 Potatoes (Oranges worked too) Background: How it works * A potato can be used as a battery by using strips of zinc and copper in the acidic juice of the potato to provide power to a digital clock. * With the zinc strip, the natural acid in the potato dissolves the zinc freeing electrons. * The copper wire uses the electrons that the zinc wire frees. * To obtain enough electrical current to power the clock, two potatoes must be used and they must be connected in a head-to-tail series. Steps: 1. Put potatoes into containers to stabilize them. 2. Insert Zinc strip from the clock into the left potato. 3. Insert Copper end of the loose strip into the same potato, 2 cm apart and parallel to the Zinc strip. 4. Insert Zinc end of the loose strip into the right potato. 5. Insert Copper strip from the clock into the same potato, 2 cm apart and parallel...

...The objectives of “Lab 8: Lemon Car Competition” were to use redox reactions to store energy in capacitors, to learn about battery cells and construct a lemon citrus cell to power devices, and to build a vehicle powered by either a lemon battery or a capacitor to be entered in a competition. The competition objective was to win the competition. The winner was the vehicle with the highest competition ratio, which was calculated using Equation 1 below. To have the highest competition ratio, the cost and time traveled were minimized and the distance traveled was maximized. The designed vehicle came in last place along with three other vehicles because it did not travel. The car costed $3.50 and traveled 0 foot, so the competition ratio was zero. Only one vehicle traveled, and therefore placed first. The first placed vehicle cost $2.50, and traveled six feet in 19.30 seconds, earning a competition ratio of 17.82. The lab was unsuccessful because the lab objective was achieved meanwhile the competition objective was not. Introduction Electrical energy can be created using a citrus cell, or a battery cell, with a chemical half reaction. Two dissimilar metals are placed in a citrus juice, which serves as an electrolytic solution. The voltage is produced because of electron movements that take place as results of the two metals’ different chemical properties such as electronegativity and ionization energy (NYU SOE 2017). Electronegativity is a measure of the attraction force of an element...

...For this experiment, you will need the following materials: 4 lemons or potatoes 4 galvanized nails 4 U. S. copper pennies (minted before 1982 due to the change in copper content) or 4 copper wires an LED light a knife 5 alligator test leads 3.)Using the knife, slice a penny-sized slit on the right side of your lemon. Push the penny far into the lemon, leaving a small area to hook your alligator jumper to. This will be your positive terminal. Now, create the negative terminal for your battery. Stick one of the galvanized nails into the left side of the lemon, about 2 inches away from the penny. It is important to have the nail and penny separated. If they touch, it will cause a short. Repeat this process until you have 4 complete batteries....
