I'm assuming this is a school science project in which case the answers are: # The materials required are pretty cheap and easy to get hold of # The health and safety considerations are pretty easy # The minimum science involved to do the experiment and understand the basic results is reasonably accessible but a full explanation of everything going on would stretch a top ability high school graduate. # The results are pretty consistent so your teacher can assess if you have done it right. Hint - If your best battery is made with a banana and 2 copper electrodes you probably got it wrong........ In summary its a good science project that allows you to learn, show what you know and doesn't create 2 many problems for your school.

The one in red light would probably grow better.
