Hey! does anyone have any practical idea for a level 6 (3rd uni year) dissertation project idea?

Hey
Hope this is an okay place to post this!
Im moving into my 3rd year of a human biology degree and have to come up with a testable working hypothesis (and then test it) for my level 6 dissertation. The issue here is I actually wants to go into teaching, as this side of science isn't my forte, does anyone have any ideas for a project title, or an area I can look into. My personal interests are immunology, nuerobiology and microbiology but any ideas related to biology (not ecology, conservation or zoology) would be most welcome!
