|Experiment Title:||Determining witch food – lemon, potato, cookie – would generate electricity|
|What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.:||The purpose of my experiment was to determine witch food – lemon, potato, cookie – would generate the enough electricity to power a clock.|
|What was your hypothesis?:||My hypothesis was that the lemon and potato would have enough electricity to power the clock. I did not think the cookie would have any electricity, at least not enough electricity to power the clock.|
|What materials did you use in your experiment? List them all.:||I used:
7. zinc strips
|What procedure was followed? Provide a brief description of the steps you followed during your experiment.:||I cut the lemon, potato, and cookie in half with my knife.Then I stuck the 2 forks in opposite halves of the lemon.
Next, I stuck the zinc strips in opposite halves of the lemon.
Then I attached the clock wires: 1 to the fork, 1 to the opposite side zinc strip.
Then I used the white wire to attach the remaining fork to the remaining zinc strip.
Then repeat these steps with the potato and the cookie.
|What were the results of your experiment?:||The results were the lemon worked the best, potato was 2nd and the cookie didn’t work at all.|
|What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect? What did you learn?:||My hypotheses were completely correct. I learned that you can use a lemon as a battery. Before today, I thought only potatoes would work. In my hypothesis, I said lemons would work because on the box there was a picture of the lemon working. But now I know that lemons work better than potatoes.|
