How To Do A Research Cause My Schooling Has Failed Me ?

I’m supposed to do a research and a report about water retention gel and Lende process. The thing is I don’t know how to start and where to find resources.

So how do y’all do a research? Are there websites that can help me find resources directly? (cause that’s the main problem, I think)

What tricks do you know I can use to facilitate doing a research?
