Kindly tell us in what sort of organisation you will be doing the internship and the number of employees they have, the duration of your internship, etc. This information will help us to give an appropriate advice.
When I was doing my Diploma in Management Studies and a Master Degree, in part-time mode, my own employers refused to let me conduct surveys. Hence, you also need to consider whether the organisation that you are considering will allow you to do the survey.
Also, kindly read the interview of an intern at
https://www.graduate-jobs.com/intern...case-study.jsp and that will give you some idea of what to do during your internship.
