What effect does temperature have on the ripening process of a fruit?. There are lots of practical problems to overcome, most importantly how to change the soil so that it has different amounts of respiration. Investigate how different species of plants respond differently to environmental stimuli. If you are still not dissuaded then be sure to collect enough data and try to be analytical, don't mix types of music and tempos of music and try to keep the investigation to some biological cause or effect. There are many possible variations, perhaps the presence of animal excrement could be the causal factor, otherwise some species may be more resistant to scratching and disturbance, caged animals can selectively graze on parts of a lawn, just to mention a few ideas. Independent, Dependent variables need to be highlighted, as should the hypothesis. By testing people of different ages to see if there is a difference in their reaction time it may seem like a simple study, but there are a lot of factors which need to be controlled and it will be difficult to find enough participants to create a large enough data set.
