What is the best graph to use for this data? Retrieved November 21, 2011, from Word Press. Assessment Pre-Activity Assessment Brainstorming: In small groups, have students engage in open discussion. How would you recommend that we graph this and which graph would be good to use? Drawing the circuit diagram prior to conducting the experiment minimizes the chances of errors. Science Buddies materials are free for everyone to use, thanks to the support of our sponsors. Poured the salt water over a black piece of paper and left near a window to allow the water to evaporate.

Potato Power!

They can provide much more current than potatoes and other fruits and vegetables, and may damage your multimeter. Placement of the nail, penny and alligator clips. Refer back to Figure 3 in the Introduction if you need a reminder about the difference between series and parallel connections. It's a fun science project that helps show the way things work in a battery by using everyday items we see around the house. A: You can use a simple setup to determine if the current measurement function of your multimeter is working. The flow of electricity is called an electrical current, which is measured in a unit called amperes A also called amps for short. Now insert one copper nail into each potato, making sure that they are as far away as possible from the galvanized nails.

Potato Power

Potato Battery Experiment Hypothesis The Hypothesis for this experiment is that the juices in potatoes contain chemicals which can facilitate electricity generating chemical reactions with the help of electrodes. The multimeter setting to measure current is shown in Figure 7. If you took photos, you could still present results qualitatively with the photos as evidence of different outcomes. It will require a 9 V battery, which is not included in your Veggie Power kit. Try other vegetables or fruits and compare voltage output with the same electrode metals.

Below are some scientific principles and concepts of potato battery experiments that would be helpful for you to understand in order to plan your project. The potato is not a source of electricity by itself. We gave a piece of each one to 5 of his friends. Another very interesting fact I found out through research was: the first battery that was designed in 1799 created by a man named Alessandro Volta. A bar graph showing one measurement: the voltage for voltaic pile consisting of 2 pennies and 2 nickels. You might have to play around with the number of potato pairs connected in series to achieve the objective. Please click on the safety icon to view the safety precautions.

If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. The electrolyte causes a chemical reaction in which the zinc becomes zinc oxide and the magnesium oxide gains electrons. They decided which one was most tender down to the least tender. Answer: No, you would need one more lemon or apple. Second, as explained in the , in order for a chemical reaction to occur and produce electricity, the electrodes must be two different types of metal. Repeat steps one through six three times.

A Battery That Makes Cents

If necessary, use scissors to trim the corners of the paper towel squares so they do not hang down and touch the paper towels below them. Isn't the power of engineering creativity amazing? In the potato battery, there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. A battery's open-circuit voltage is the voltage across a battery's terminals when it is not attached to anything. They can contribute to heavy metals that potentially may leach from solid waste landfills. Check to see if the clock is working. In this way, the process that produces the electrical energy continues and becomes useful.

Next, insert a copper coin halfway into the potato about 1 inch away from the nail. A battery is an electrochemical device with the ability to convert chemical energy to electrical energy to provide power to electronic devices. It will help create good electrical contact with the bottom penny of your pile. The russet potato had the highest amount of voltage at 4 amps. Volts voltage is a measure of the force moving the electrons. I have liquids such as water for the control, soda, tea, coffee, energy drinks and cold chocolaty drink.

Potato Battery Experiment with Hypothesis and Conclusion

You can purchase most of these materials at your local hardware or hobby store, or you may even have some of them at home already. I chose this topic because I have an interest in making batteries out of things we use every day, such as fruit and vegetables. Well, potatoes contain phosphoric acid which can serve as the chemical solution necessary to transfer electrons back and forth between the metal plates. Stevens holds a General Certificate of Education from Chelmsford College of Further Education. My project has to do with having many different liquids in which an egg is being dumped into. Certain types of metals — particularly copper and zinc — react with the potato when they are inserted inside. The ions carry electrical charge from one electrode to another, completing the electrical circuit.

Problem: Can Potato be used to generate electricity? Below is a list of things to check. Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. A few pennies and nickels, small paper-towel squares, a vinegar-salt solution, and an aluminum strip is all you need to create a coin battery. First, what was your question? How exactly do the voltage and current change when your batteries potatoes are configured in series or in parallel? When electrical current flows through a source of resistance, it can be changed into light or heat or sound. Retrieved June 25th, 2013, from.
