Yes, the purpose of doing the experiment should be to answer the question you posed when you came up with the experiment. On your display board, your results/conclusions should be geared toward answering or at least discussing this question.
That said, I think you might want to consider re-wording your question a little, but I'm not sure because I don't know what exactly you did. Can you tell us about your experiment? I suspect you may have actually answered the question, "Do herbal remedies have antibacterial properties?"
so that should be my question? my hypthesis/question is
If I combine the tannic acids from the black tea and the citric acid from a lemon the foot will seem cleaner, they will perspire less, and the muscels will be more relaxed. Why does this happen?
But what you're saying is my question would be better seved as "Do herbal remedies have anitibacterial properties?" I think that makes more sense now. And we answer the question through the experiment but also in the conclusion part of the report????

From what you've written, I don't see how your experiment has anything to do with antibiotics? Are you comparing to antibiotics in any way, or using petri dishes to look at bacteria? If not, then a more appropriate hypothesis might be, "Herbal remedies make feet cleaner, drier, and more relaxed" but it's hard to tell without knowing what your experiment was.
