Statement of the problem for potato battery
1 1 introduction 11 problem statement the purpose of this project is to identify the effect that surface modifications have on the urban heat island phenomenon and related ozone problem in the metropolitan area of chicago. Problem/question can fruit with citric acid produce enough electricity to power a small led light bulb in a lemon battery the electricity comes from the chemical reaction between the copper & zinc electricity- is a electric power that is made by atoms and electrons it is a electrical charge and it is. Always remember to connect the copper (positive) end of the potato (battery) to the zinc (negative) end of the next potato (see figure 2) figure 2 activity setup to create a potato battery to power an led clock. Potato battery essay sample statement of the problem: this study aims to determine if potatoes could be potential battery alternatives specifically, it sought to answer the: 1 if you answered yes, then here is the solution to your problem potato batteries are designed for you so why 279 words 2 pages.
Project problem statement and justification agriculture in east africa is characterized by women and men working in small scale, rainfed production, averaging 2 hectares per household (fao 2006. The lemon battery you made is a type of battery called a voltaic battery these types of batteries are made of two different metals, which act as electrodes , or places where electrons can enter or leave a battery. The potato battery is a type of electrochemical battery, or cell certain metals (zinc in the demonstration below) experience a chemical reaction with the acids inside of the potato this chemical reaction creates the electrical energy that can power a small device like an led light or clock.
The potato battery is simple enough to craft, using a potato, some insulated copper wire, a galvanized nail and a penny coin according to pbs kids, all you need to do is simply cut a potato in half then wrap a piece of insulated copper wire around a galvanized nail on one end wrap another piece around a penny. A potato's acidity is determined by a combination of the potato's strain, the ph of the soil in which it was grown, and the method of storage the acid can be used in a chemical reaction to generate electricity, much in the same way a chemical battery functions. Hi all i was originally drawn here for some of the potato battery questions, and ended up doing my science fair on it i took pears, lemons, limes, carrots, and potatoes, and tested them with this method to see which could produce the most voltage. Leds require more than 2 volts to light up each zinc-copper potato produces 1 volt in this particular setup, we've created 3 - 1 volt batteries connected in a series so that they can light up an led please see photos for directions also see metal reactivity series table to learn more see.
(analog multimeter gets its power from our potato to show the voltage, but digital multimeter gets its power from an internal battery and does not consume any of the electricity produced by our potato, that is why it shows a larger and more accurate value. Would a potato, apple or onion battery work try a few from around the kitchen (with permission, of course) does one particular fruit or vegetable outperform the others. Did you know you could power a light bulb with a potato the chemical reactions that take place between two dissimilar metals and the juices in the potato create a small amount of voltage that can power a very small electrical device [source: madsci]follow the instructions below to make a potato-powered light bulb. 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.

Circle the letter of the statement that is always true about a battery a scientific problem is often discovered when what is made, which leads to a question advchemistry chapter 1 21 terms section 21 properties of matter 24 terms chemistry chapter 2 features. Potato battery investigatory project :p embed share print search related titles investigatory project potato powered battery militante-bello potato as a battery science investigatory project paper investigatory project statement of the problem this study developed that a potato can light a bulb that will help us to conserve. The answer is, even if we connected several lemon batteries together (in series) to get the same voltage as in a d cell battery, the current we can get out of a lemon battery is just too small to light the bulb.
You can hook the batteries up in parallel to get more current out of the combination battery at the same voltage as one battery, overcoming the resistance problem slowly, at the expense of more copper, zinc, (and space on your potato. The purpose of this experiment is to determine whether there is enough energy stored in a fruit or a vegetable to power an led light this experiment can be taken further to determine how long a fruit or vegetable can power an led for with the help of a few household items, a potato can be used to. The problem statement is the most important part of a science fair project this single phrase defines and directs all of the work you will be doing before you can begin to develop and execute your experiment, you must have a clearly defined problem that will be addressed by your project in the.
