Fair testing

Currently Room 15 are conducting an experiment. Here's what we did: First we planted some grass in yogurt contains.
       Then we made some coffee and tea and got some Hot                       water,Coke,Tap water, and some oil

 We decided that we would keep them growing for two weeks being fed every morning a tablespoon of liquid. Currently Coffee,Tap Water,Tea and hot water are growing best. We found that when we poured coke onto the plants the carbon dioxide would fizz and make a hole in the dirt. The question we want answered for this experiment is What liquid is best for your garden? We cant wait to see how this turns out.
