...cheap and readily-available materials, this project can provide households with an alternative source of light that can easily be done and replicated. Although this may seem as a step back for advancements in technology because it makes use of household materials instead of more complicated ones, this is one step ahead towards innovation. b. STATEMENT OF THE PROBLEM Can Vinegar be used as a battery for lighting small LED bulbs? c. SIGNIFICANCE OF THE STUDY The researchers chose this investigatory project of vinegar being used as a battery for lighting LED lights for two of its possible contributions to the community: first, it can be used as a safe, better and cheaper alternative to sources of lights in case of blackouts, and second, people can use it as an alternative source of light at home to lower their power consumption. The Philippines is an archipelago surrounded by large bodies of water making it susceptible to typhoons. The last devastating typhoon, Yolanda, had left Leyte and other parts of the country in turmoil with no food, water, and electricity for not just days but for months, and this will not be the last time that a huge typhoon will hit the country and leave another part of our archipelago helpless. With this project, the researchers wish to provide the people, especially those in provinces who are most badly affected by these typhoons, with an alternative source of light in their homes without having to spend too much and with readily-available...

...Introduction A simple battery can be constructed with a cup, a copper strip, and a zinc strip. Attach wires to each strip and place them in the cup. Place the strips in the cup and add either Coca Cola or vinegar to the cup. If a voltage meter is placed across the leads, it will show between 0.75 and 1.0 volts. More voltage can be created by adding several of these cells in series. Vinegar is a liquid consisting mainly of acetic acid (CH3COOH) and water. The acetic acid is produced by the fermentation of ethanol by acetic acid bacteria. Vinegar is now mainly used as a cooking ingredient, but historically, as the most easily available mild acid, it had a great variety of industrial, medical, and domestic uses, some of which (such as a general household cleanser) are still promoted today. Commercial vinegar is produced either by fast or slow fermentation processes. In general, slow methods are used with traditional vinegars, and fermentation proceeds slowly over the course of months or a year. The longer fermentation period allows for the accumulation of a nontoxic slime composed of acetic acid bacteria. Fast methods add mother of vinegar to the source liquid before adding air using a venturi pump system or a turbine to promote oxygenation to obtain the fastest fermentation. In fast production processes, vinegar may be produced in a period ranging from 20 hours to three days. An electric battery is a device consisting of one or more electrochemical cells that convert stored...

...CHAPTER I INTRODUCTION Background of the Study With limited sources of electricity in the Philippines, we discerned that this problem needs attention or better yet solved. At present, Mindanao today has been experiencing power shortage because of lack of hydroelectric energy for the power depends on the availability of Maria Cristina Falls’ water, which is also affected by weather conditions. In view of this, people from the place tend to find an alternative source of energy. We have found out that the fruit, santol (Sandoricum koetjape), contains citric acid that could produce electrical energy. At present, the Cottonfruit (Sandoricum koetjape) is an abundant fruit locally. Statement of the Problem The study aims to produce electrical energy with the use of an ordinary household Cottonfruit (Sandoricum koetjape) by making it as a battery. Specifically, it seeks to answer the following questions: 1. How much volume of Cottonfruit (Sandoricum koetjape) is needed to light a 5V bulb? 10V? 2. Are there other chemical contents of Cottonfruit (Sandoricum koetjape) that could create electrical energy aside from citric acid? If other citric fruits such as Orange (Citrus aurantium) and Calamansi (Citrofortunella microcarpa), could the product be more effective and conductive? Significance of the Study The study aimed to create electrical energy from Cottonfruit (Sandoricum koetjape) Typically; cottonfruit is a common fruit in the Philippines. The result of the study...

Introduction Vinegar is a liquid produced from the fermentation of ethanol in a process that yields its key ingredient, acetic acid. The acetic acid concentration ranges typically from 4 to 8 percent by volume for table vinegar [1] (typically 5%) and higher concentrations for pickling (up to 18%). Natural vinegars also contain smaller amounts of tartaric acid, citric acid, and other acids. Vinegar is an important preservative and condiment and it is being produced since centuries. It is produced through the action of acetic acid bacteria on dilute solutions...

...Types of Word Formation Processes Compounding Compounding forms a word out of two or more root morphemes. The words are called compounds or compound words. In Linguistics, compounds can be either native or borrowed. Native English roots are typically free morphemes, so that means native compounds are made out of independent words that can occur by themselves. Examples: mailman (composed of free root mail and free root man) mail carrier dog house fireplace fireplug (a regional word for 'fire hydrant') fire hydrant dry run pick-up truck talking-to In Greek and Latin, in contrast to English, roots do not typically stand alone. So compounds are composed of bound roots. Compounds formed in English from borrowed Latin and Greek morphemes preserve this characteristic. Examples include photograph, iatrogenic, and many thousands of other classical words. Note that compounds are written in various ways in English: with a space between the elements; with a hyphen between the elements; or simply with the two roots run together with no separation. The way the word is written does not affect its status as a compound. Over time, the convention for writing compounds can change, usually in the direction from separate words (e.g. clock work), to hyphenated words (clock-work), to one word with no break (clockwork). If you read older literature you might see some compound words that are now written as one word appearing with unfamiliar spaces or hyphens between the components Another...

...BATTERY ON THE GO (Vinegar Battery) Submitted by: Hanna Guerrero Marielle Reyes Bea Villanueva Adriane Victorino • ACKNOWLEDGEMENT This investigatory project would not be possible without the people who guided and supported us while doing this activity. First, we would like to thank our parents who supported with us with the financial support that we need. Second, to our science teacher, Ms. Flora Andal who provided us with the ideas that we applied in our project. And most of all, we give our deepest gratitude to our God for He is the reason behind all these success. Chapter 1: INTRODUCTION A. Background of the Study * We chose this project because it is simple yet very interesting. Based on our research, many had tried to do this activity. Some of them were successful while the others are not. Based on their opinions, they said that this project is simple but very helpful for the other people who suffers from brownouts. The thing that pushed us to choose this topic is because the Philippines is now suffering rotational brownouts due to the problems of the power plant. This vinegar battery can help the affected families have an alternative energy supply. B. Statement of the problem/Objectives * This investigatory project aims to: a. Use for alternative purposes especially when there’s no electricity. b. Help other people have alternative batteries. c.

...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...
