Conclusion
Our problem was which type of metal produces the most electricity? We concluded that the two soda cans would produce the most electricity but we where wrong. The two soup cans did produce the most electricity. The piece of metal went back and forth 39 times in 15 seconds. We also tested two pieces of copper wire, one piece of copper wire and a soda can. The two soda cans came in second with 30 times in 15 seconds. The two pieces of copper wire came in third with 25 times in 15 seconds. The copper wire and one soda can came in forth with 24 times in 15 seconds.
