  2. What can make a battery?Can a battery be made with different objects?

  3. Hypothesis: • I believe that both natural and man made materials can make a battery.

  4. Research Information: • http://chemistry.about.com/od/chemistryhowtoguide/a/fruitbattery.htm • Citrus fruits are an acid that can make electricity for a battery such as a lemon. • http://www.pbs.org/weta/roughscience /discover/powerplant.html • Some batteries make electricity with a chemical reaction between two different metals which are zinc and copper. • http://www.associatedcontent.com/article/701811/how_to_make_a_battery_with_a_lemon • Contains instructions on how to make a battery with a dime and a penny.

  5. Research Information: cont • Green Science Enviro Battery Kit • A zinc plate is a negative electrode. A copper plate is a positive electrode. When they are put into the electrolyte such as lemon juice a chemical reaction takes place that makes electricity. • The Way Things Work, by David Macauly Science information book • A battery has powdered zinc and mercury oxide in an alkaline electrolyte. • A car battery has plates of lead oxide and a lead metal used in sulfuric acid electrolyte.

  6. Materials List • Connection wires • Transparent tape • 3 glass cups • Light tower with LED lamp • LCD watch moment • Sound chip • Copper plates • Zinc plates

  7. Materials List cont. • Two lemon • Two potatoes • Two cups of dirt • Three cups of water • A pumpkin • Salt • Vinegar • Lemon juice

  8. Procedures: Potato • 1. With the connection wire place the copper and zinc plates in the potato. • 2. Attach the LCD watch to the copper and zinc plates put in the potato. • 3. Connect the wires and watch.

  9. Procedures: Lemon • 1. With the clock put the wires in the lemon • 2. Observe the clock.

  10. Procedures: Water • 1. Get 3 bottles of water and put 1 copper, and 1 zinc in each bottle. • 2. Connect the wires and watch the light.

  11. Observations Analysis Table

  12. Observations Continued

  13. Conclusion • My hypothesis was correct. Both natural and man made materials can make a battery. • While doing the experiment I found that stuff with the most acid powers the best. • I would change my pumpkin experiment because it did not have enough power for anything.
