Best metal for your electrodes?

Ok. I am making wet cell batteries filled with lemon/lime/grapefruit juice for my 8th grade science fair project and I need to know what would be the best metals to use for the elecrodes. I was thinking maybe copper anodes and zinc cathodes. is that good enough or can I go with a better combination?
any advice would be very much appreciated.
