The next paragraphs in the introduction should cite previous research in this area.
It should cite those who had the idea or ideas first, and should also cite those who have done the most recent and relevant work.
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.
In most circumstances, this is best accomplished by physically separating statements about new observations from statements about the meaning or significance of those observations.
Alternatively, this goal can be accomplished by careful use of phrases such as "I infer ..." vast bodies of geological literature became obsolete with the advent of plate tectonics; the papers that survived are those in which observations were presented in stand-alone fashion, unmuddied by whatever ideas the author might have had about the processes that caused the observed phenomena.
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.
This is a statement of something sufficiently interesting to motivate your reader to read the rest of the paper, it is an important/interesting scientific problem that your paper either solves or addresses.
You should draw the reader in and make them want to read the rest of the paper.
