Please submit 3-4 pages of your investigative essay, it need not be the first 3-4 pages, it can be chunks of what you’re working on with other parts outlined, but tell me at the very beginning in a note:
1.) What it is you’re turning in.
2.) What you’d like feedback on.
3.) What you’re having trouble with or questions you have.  
I typically read these quickly and tell you what else I expect to see.
