What is the one thing you want your audience to learn?
Your goal is to convey a clear message and support it with a compelling combination of images and short blocks of text.
If it doesn't reinforce your message, leave it out!
State your key result explicitly in the title: Water Temperature Affects Flounder Growth Rates
Make the strongest statements your data will support. Why soft-peddle exciting findings? "Substance X is essential to apoptosis in Y cells."
Interpret your findings in the conclusion - what do they mean? "Greenways must be wider to support forest interior birds." (Of course, your results must support such a statement.)
Make the title as non-committal (and boring) as possible: The Effect of Water Temperature on Flounder Growth Rates
Avoid committing yourself to any strong statements. Add qualifying words in abundance, such as probably, perhaps, may, might. "Antibody to X probably abolishes the response."
In the conclusion, instead of interpreting your data, merely repeat the results and then say further study is required. "The effect of greenway width on forest interior birds needs further study." Since virtually everything needs further study, you can't be faulted.
