Our problem is what selected fruits and vegetables has the most voltage and runs a clock for the longest. Our hypothesis is that all of the fruits and vegetables will generate energy but we predict that the grapefruit will work best because we think the acid will help. Our hypothesis was wrong the grapefruit finished second running the clock for 52 hour. The cantaloupe lasted the longest running the clock for 91 hours. Some major factors that would have affected our experiment is the size of the fruit or vegetable it could make the clock run longer or shorter. Our result could help us in the real life if we ever want to use an environmentally friendly way top run things that don’t take very much power.
