Last Year Science Fair

Aim

To find what fruit or vegetable generates the most power.

Hypothesis

I think that the lemon will make the most power because it is the most acidic

Introduction

I always wanted to make a potato batterie but I wondered what would happen with other fruits so I decided to try at this science fair.

Equipment & Method

Various fruit and vegetables

1 small copper rod

1 small zinc rod

a voltmeter

What I did was put the copper rod in one end of the fruit and then put the zinc rod in the other end , attached the voltmeter the the rods and then I got a reading. I tested this 3 times to get an average for each thing

Results

The results were that the potato and the lemon made the most power and the tomato made the least

Conclusion

I conclude that the lemon generated the most power out of the 3 trials

maybe hover shoes or different effect of video games
