Science Buddies: "Ask an Expert"

I need help on the anaylizing data part of my fruit batteries project. I used 3 potatoes to power up a 3-volt watch and it works. I just don't know what to write for the data. Please help.

please.

What was your hypothesis? We can't help you with analyzing results without knowing what hypothesis you are testing.

Good science fair projects utilize the Scientific Method. The getting started information on https://www.sciencebuddies.org/science- ... ndex.shtml is intended to help guide you through understanding the Scientific Method and how it guides you through developing a hypothesis that is testable, coming up with an experiment that will prove/disprove the hypothesis using a fair test, and then on into analyzing your data and presenting it as a finished project.

The Project Ideas as written aren't a cook book recipe that you can just follow to do a science fair project. As written, they are more of a demonstration of some scientific principles that don't involve a hypothesis. That is something that you have to add in order to make them into a good science fair project.

Hi - I'm posting the link to the project I think you might be referencing here:

Veggie Power! Making Batteries from Fruits and Vegetables

Follow up with more information about your hypothesis, as Craig indicates above, and hopefully the team of experts will be able to help!
