develop a strong hypothesis with good intellectual content potential
Look up background information in your book about the physiological mechanisms you are interested in and what is already known about them
Design the experiment thinking about the best treatments and controls to isolate your factors of interest
Think about potential outcomes and their implications – if you get pattern A it will mean X, if you get pattern B, it will mean Y, etc.
Can you foresee any issues in coming to clear conclusions?
You might want to strengthen your hypothesis or adjust your experimental design
Think about potential to develop your intellectual content by highlighting your hypothesis through the introduction, methods, results, and discussion — given your hypothesis, what are important points to hit?
Maximize your intellectual merit by writing to convince the reader that your study is important, useful and compelling.
