You should then go on to explain why more work was necessary (your work, of course.) Quarantine your observations from your interpretations.The writer must make it crystal clear to the reader which statements are observation and which are interpretation.
Therefore, you should construct your paper so that it can be understood by skimming, i.e., the conclusions, as written in your abstract, can be understood by study of the figures and captions.
The text fills out the details for the more interested reader.
This section should be rich in references to similar work and background needed to interpret results.
However, interpretation/discussion section(s) are often too long and verbose.
If at all possible, start your thesis research during the summer between your junior and senior year - or even earlier - with an internship, etc. then work on filling in background material and lab work during the fall so that you're prepared to write and present your research during the spring .
The best strategy is to pick a project that you are interested in, but also that a faculty member or other professional is working on.
Consider writing the introductory section(s) after you have completed the rest of the paper, rather than before.
Be sure to include a hook at the beginning of the introduction.
Because of the literature explosion, papers more skimmed than read.
Skimming involves reading the abstract, and looking at the figures and figure captions.
