Why is it important to write down your ideas and discoveries when you conduct initial research on a topic?

It is major to do so because you need to include works cited page for no plagiarism, and to keep organized for no repeated expounds of info.
and to prove your facts its important to write down your ideas and discoveries when you conduct intial reserach because without proof the professor will not b able to knw whether you tested your facts or not and inestigated properly or not

Is there more to the question? i would if i knew the whole question. sorry : )
