Science Buddies: "Ask an Expert"

I have a question about the time in needs. Is it possible to record the date over a few days? Ir does it have to be over a span of 30 days?

Hi Michelle,

I assume you are referring to this project: https://www.sciencebuddies.org/science- ... background

I suspect that you will not see much electricity if you try to do this project over only a few days. It likely takes some time for the bacteria to start breaking down the waste, so you probably won't see much electricity in just a few days, which might not make for a very exciting project.

I hope this helps!
