Battery and Jumper Cables
Investigatory Project 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. I 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 my pockets. This idea turned out to be realty and became the main goal of my 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, I 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. I 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. I 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 a decent circuit. My thoughts on which will be the best conductor were different. Some said that the lemon is the best conductor due to its acidity. Some say it’s the banana due to its efficiency. Yet some also say it’s the orange due to its fame as a fruit.
D. Significance of the Study My main reason for making this research is not only to make a variation on the commercial DC cell, but to also do my part in saving our Earth. By having organic batteries,
